Abstract

The rise of gas-sensing applications and markets has led to microwave sensors associated to polymer-based sensitive materials gaining a lot of attention, as they offer the possibility to target a large variety of gases (as polymers can be easily functionalised) at ultra-low power and wirelessly (which is a major concern in the Internet of Things). A two-channel microstrip sensor with one resonator coated with 1,2 epoxybutane-functionalised poly(ethyleneimine) (EB-PEI) and the other left bare was designed and fabricated for humidity sensing. The sensor, characterised under controlled laboratory conditions, showed exponential response to RH between 0 and 100%, which is approximated to −1.88 MHz/RH% (−0.03 dB/RH%) and −8.24 MHz/RH% (−0.171 dB/RH%) in the RH ranges of 30–80% and 80–100%, respectively. This is the first reported use of EB-PEI for humidity sensing, and performances, especially at high humidity level (RH > 80%), as compared with transducer working frequencies, are better than the state of the art. When further tested in real outdoor conditions, the sensor shows satisfying performances, with 4.2 %RH mean absolute error. Most importantly, we demonstrate that the sensor is selective to relative humidity alone, irrespective of the other environmental variables acquired during the campaign (O3, NO, NO2, CO, CO2, and Temperature). The sensitivities obtained outdoors in the ranges of 50–70% and 70–100% RH (−0.61 MHz/%RH and −3.68 MHz/%RH, respectively) were close to lab results (−0.95 MHz/%RH and −3.51 MHz/%RH, respectively).

Abstract

The past few decades have witnessed the ultra-fast development of wireless telecommunication systems, such as mobile communication, global positioning, and data transmission systems. In these applications, radio frequency (RF) acoustic devices, such as bulk acoustic waves (BAW) and surface acoustic waves (SAW) devices, play an important role. As the integration technology of BAW and SAW devices is becoming more mature day by day, their application in the physical and biochemical sensing and actuating fields has also gradually expanded. This has led to a profusion of associated literature, and this article particularly aims to help young professionals and students obtain a comprehensive overview of such acoustic technologies. In this perspective, we report and discuss the key basic principles of SAW and BAW devices and their typical geometries and electrical characterization methodology. Regarding BAW devices, we give particular attention to film bulk acoustic resonators (FBARs), due to their advantages in terms of high frequency operation and integrability. Examples illustrating their application as RF filters, physical sensors and actuators, and biochemical sensors are presented. We then discuss recent promising studies that pave the way for the exploitation of these elastic wave devices for new applications that fit into current challenges, especially in quantum acoustics (single-electron probe/control and coherent coupling between magnons and phonons) or in other fields.

Abstract

This paper presents the feasibility of a fully inkjet-printed, microwave flexible gas sensor based on a resonant electromagnetic transducer in microstrip technology and the impact of the printing process that affects the characteristics of the gas sensor. The sensor is fabricated using silver ink and multi-wall carbon nanotubes (MWCNTs) embedded in poly (3,4-ethylenedioxythiophene) polystyrene (PEDOT: PSS-MWCNTs) as sensitive material for Volatile Organic Compounds (VOCs) detection. Particular attention is paid to the characterization of the printed materials and the paper substrate. The manufacturing process results in a change in relative permittivity of the paper substrate by nearly 20%. Electrical characterization, made in the presence of gas, validates our theoretical approach and the radiofrequency (RF) gas sensor proof of concept.

Abstract

Cancer is a leading cause of death worldwide and actual analytical techniques are restrictive in detecting it. Thus, there is still a challenge, as well as a need, for the development of quantitative non-invasive tools for the diagnosis of cancers and the follow-up care of patients. We introduce first the overall interest of electronic nose or tongue for such application of microsensors arrays with data processing in complex media, either gas (e.g., Volatile Organic Compounds or VOCs as biomarkers in breath) or liquid (e.g., modified nucleosides as urinary biomarkers). Then this is illustrated with a versatile acoustic wave transducer, functionalized with molecularly-imprinted polymers (MIP) synthesized for adenosine-5′-monophosphate (AMP) as a model for nucleosides. The device including the thin film coating is described, then static measurements with scanning electron microscopy (SEM) and electrical characterization after each step of the sensitive MIP process (deposit, removal of AMP template, capture of AMP target) demonstrate the thin film functionality. Dynamic measurements with a microfluidic setup and four targets are presented afterwards. They show a sensitivity of 5 Hz·ppm−1 of the non-optimized microsensor for AMP detection, with a specificity of three times compared to PMPA, and almost nil sensitivity to 3′AMP and CMP, in accordance with previously published results on bulk MIP.

Abstract

Lossy mode resonance (LMR)-based optical sensors change their wavelength upon contact with substances or gases. This allows developing applications to detect the refractive index of the surrounding medium and even the thickness of the biolayers deposited on the waveguide. In the same way, when acoustic sensors are in contact with a liquid, it is possible to determine parameters, especially mechanical ones such as shape of the particle or molecule, mass load, elastic constants and viscosity of the liquid. This work reports the development of a system that combines LMR with surface acoustic wave (SAW) technologies to characterize a liquid in terms of its refractive index and viscosity simultaneously. Conveniently prepared glucose solutions are used for sensor calibration. The refractive index of the solutions ranges from 1.33 to 1.41 and its viscosity ranges from 1.005 mPa·s to 9 mPa·s, respectively. A sensitivity of 332 nm per RIU has been achieved with the optical sensor while the acoustic sensor has shown a sensitivity of −1.5 dB/(mPa·s). This new combinational concept could be expanded to the development of more demanding applications such as chemical sensors or biosensors.

Abstract

International audience; This paper elaborates on an instrumental scheme for translating electrochemical reactions occurring at an electrode under potentiostatic control into fluorescent signals. We examine the performance enhancement of this device using recently introduced water-soluble fluorescent reporter systems, either the pH-sensitive 8-hydroxypyrene-1,3,6-trisulfonic acid (HPTS) system or the electrofluorogenic Amplex Red species. The conversion of stationary and transient, cathodic and anodic electrochemical currents into fluorescence is demonstrated. We show that pure capacitive currents can also be converted to fluorescence by our setup, highlighting the rarely observed coupling between a faradaic reaction at one electrode and capacitive charging at another.

This paper proposes an innovative differential sensor based on planar microwave transducers printed on flexible substrate by low-cost printing technologies and operating at ambient temperature. The gas detection is obtained from a differential approach between a reference channel and gas sensitive one based on PEDOT: PSS-MWCNT. A preliminary sensor is fabricated and tested around 3.6 GHz. The experimental behavior in the presence of ethanol vapor is encouraging and validates the proof-of-concept.

Abstract

International audience; This paper presents a new paradigm in the analysis and methodology for Surface Acoustic Wave (SAW) devices for sensing application in a liquid medium. Th new protocol encourages the analysis of the electrical and electro-acoustic behavior of the sensor rather than limiting the measurement interest to mechanical interactions between the sensor and the medium. According to experimental responses, some hypotheses are proposed allowing the separation of each electrical and mechanical mechanisms based on post-treatment analysis methods. Thus, to better understand the proposed approach, we introduced a new and unconventional energy flow chart of the acoustic wave propagation in the SAW device which helped us extracting our hypotheses. This new paradigm allows us to get information related to both dielectric and mechanical parameters of a liquid sample using a single sensor, enriching the response. In contrary to most works surrounding the SAW sensors, this new method does not intend to increase the sensitivity of the sensors. Instead, it focuses on an unconventional ”holistic” approach that achieves an improved understanding of the sensitive phenomena and enriches the global response and analysis to a given characterization. Ultimately, this improved understanding could help to increase the sensitivity to a selected target using the same method. This approach could be used with all electro-acoustic sensor devices. We applied this method to Love wave sensors with different technological characteristics influencing the electric and acoustic response with numerous fluid solutions for a large diversity of dielectric constants and mechanical characteristics responses. A larger set of measurement from the Love wave sensor is obtained allowing to extract both dielectric and mechanical parameters of a liquid medium on the Love wave sensor surface.

Abstract

International audience; In this paper, we propose to study the influence of moisture on passive radiofrequency (RF) sensors associated with poly (3,4-ethylenedioxythiophene) polystyrene sulfonate - multi walled carbon nanotubes (PEDOT:PSS-MWCNT) as a sensitive material. The designed sensor consists of a copper ring resonator and two PEDOT:PSS-MWCNT stubs located in the maximum electric fields of the fundamental resonant mode operating at 3.94 GHz. For performing a differential analysis, experiments are conducted by considering the resonant structure with and without a sensitive layer. Our experiments show the high interference of humidity on the sensor’s performances and highlight the importance of differential study to decorrelate physical and chemical surrounding parameters. This differential innovative structure paves the way for a very high sensitive passive RF sensor dedicated for gas sensing.

Abstract

Online publication: 2018Issue date: June 2022; International audience; This study presents the results on the feasibility of a resonant planar chemical capacitive sensor in the microwave frequency range suitable for gas detection and wireless communication applications. The final aim is to develop a low cost ultra-sensitive sensor that can be integrated into a real time multi-sensing platform. The sensors presented in this article are dedicated to the detection of gases such as volatile organic compounds (VOCs) in order to monitor environmental pollution. Experiments were conducted on two devices D1 and D2 which have different geometries notably on the coupling part between electrodes and the position of the sensitive layer based on nanocomposite material PEDOT: PSS-MWCNTs. The preliminary results have shown a large influence of ethanol vapor concentrations on the electrical properties of the passive resonators that constitute each device in the frequency range from 2 to 4 GHz. The sensors sensitivity to ethanol vapor exposition has been estimated to - 0.2 and - 2.2 kHz/ppm for D1 and D2, respectively, according to the resonant frequency shifts for 500–2000 ppm concentrations. The high sensitive surface of the sensor (D2), with possible further functionalization based on various sensitive materials in a large range of electrical conductivity, make it especially interesting for the development of chemical gas sensors for different applications requiring passive and autonomous components at low cost.

Abstract

International audience; This work focuses on the different technological characteristics and physical phenomena that can produce a dispersion of performance on surface acoustic wave (SAW) sensors. Using of a sophisticated statistical approach for the study of the devices variability requires a large amount of data and can be difficult to produce or compare. Modeling may improve the understanding of the physical and technological effects, thus it can help to estimate and reduce the dispersion produced by refining the design and / or the manufacturing process. A list of design parameters assumed to be at the origin of the variations of the SAW performance is proposed. In this work, measurements of approximately one thousand samples were grouped according to their characteristics and compared by using a Finite Element Model (FEM) analysis. The obtained results support the interest of the model and of the method developed to predict the influence of geometric and physical parameters on the acoustic wave devices behaviour, paving the way for a more exhaustive stochastic approach.

Abstract

Acoustic wave sensors are given special attention since a few decades as they offer a good sensitivity for detection applications. Their ability to operate in liquid and gas media make them a very interesting device. Nevertheless, to further improve their sensitivity in term of “mass loading effect”, the increasing of the surface to volume ratio of the associated sensitive layer is a promising strategy which could overcome many of the challenges faced by the in situ detection of low mass biomolecules. This paper presents an overview of the latest works carried out on the association of Love wave transducers with SiO 2 and TiO 2 porous layers at the IMS Laboratory. The principal results are developed, and the current investigations and perspective are exposed.

Abstract

International audience; We describe the development of an original faradaic current to fluorescence conversion scheme. The proposed instrumental strategy consists in coupling the electrochemical reaction of any species at an electrode under potentiostatic control, with the fluorescence emission of a species produced at the counter electrode. In order to experimentally validate this scheme, the fluorogenic species resazurin is chosen as a fluorescent reporter molecule, and its complex reduction mechanism is first studied in unprecedented details. This kinetic study is carried out by recording simultaneous cyclic voltammograms and voltfluorograms at the same electrode. Numerical simulations are used to account for the experimental current and fluorescence signals, to analyze their degree of correlation, and to decipher their relation to resazurin reduction kinetics. It is then shown that, provided that the reduction of resazurin takes place at a micrometer-sized electrode, the fluorescence emission perfectly tracks the faradaic current. By implementing this ideal configuration at the counter electrode of a potentiostatic setup, it is finally demonstrated that the oxidation reaction of a non-fluorescent species at the working electrode can be quantitatively transduced into simultaneous emission of fluorescence.

Abstract

International audience; This paper presents the feasibility of a fully inkjet-printed, microwave flexible gas sensor based on a resonant electromagnetic transducer in microstrip technology and the impact of the printing process that affects the characteristics of the gas sensor. The sensor is fabricated using silver ink and multi-wall carbon nanotubes (MWCNTs) embedded in poly (3,4-ethylenedioxythiophene) polystyrene (PEDOT: PSS-MWCNTs) as sensitive material for Volatile Organic Compounds (VOCs) detection. Particular attention is paid to the characterization of the printed materials and the paper substrate. The manufacturing process results in a change in relative permittivity of the paper substrate by nearly 20%. Electrical characterization, made in the presence of gas, validates our theoretical approach and the radiofrequency (RF) gas sensor proof of concept.

Abstract

This paper presents an inkjet-printed differential passive microwave planar resonator-based sensor for toxic vapor detection at room temperature. Two devices are presented, with 5 (D1) and 50 (D2) layers of composite sensitive film (PEDOT:PSS-MWCNTs). Each one consists of two band-pass resonators with the fundamental modes around 2.5 and 2.7 GHz. Theoretical and experimental results are presented, both devices show sensitivity to ethanol vapor ranging from 500 to 1300 ppm according to the magnitude and resonant frequency shifts of their scattering parameters (S-parameters). Limitations due to a continuous drift on both the reference and the sensitive channels are discussed. Though further improvements are needed, such sensor is a good candidate for integration into real-time multi-sensing platforms adaptable for the Internet of Things. This work was supported in part by the French National Research Agency under Project ANR-13-BS03-0010 and in part by the “Investments for the future” Programme IdEx Bordeaux, under Grant ANR-10-IDEX-03-02.

Abstract

International audience; This paper presents the interest of a highly sensitive biosensor coated with a TiO2 mesoporous film as sensitive layer. The main novelty is related to the modelling of the device and simulation by using Finite Element Method with COMSOL Multiphysics software, as a good way to take into account the physical properties of porous 3D-layers. The strategy of using such Love wave devices, with 3D porous layers, offering further easy functionalization, aims not only to increase the amount of targets caught on the sensor surface, but also to enhance the detection mechanism by a higher perturbation of the Love wave acoustic energy which could be trapped inside the 3D sensitive layer. First, as a proof of concept, experimental devices with a 3D titania mesoporous layer were realized, and they have shown a good agreement with simulated results. Furthermore, experimental test with several Newtonian liquids are investigated, in a range of viscosities from 1 to 7 cP, typical of those concerned by our biochemical applications. The sensitivity with a 300 nm thick porous sensing layer was 10 times that of the bare device, with interesting dynamical issues to be further studied, giving rise to the great potentialities of such architectures for biological detection of low weight biochemical targets.

Abstract

Structured materials are of interest to emphasize the sensitivity of gas or bio-sensors. This work focuses on carbon-polymer composite (PEDOT:PSS-MWCNT) and additional multiwalled carbon nanotubes (MWCNT), deposited by inkjet printing on Love acoustic wave devices. This combination is studied, both with simulation based on finite element modelling and computational analysis of a reduced model, and experimental measurements. This allows for an estimation of the Young modulus of each material: 70 GPa and 150 GPa for the PEDOT:PSS-MWCNT bilayer composite material $(\equiv \ \mathbf{450 nm})$ and for the MWCNT bilayer on carbon composite $(\cong \mathbf{140 nm})$ , respectively. The value is lower than that obtained in the literature, which has been attributed to the material porosity. An enhanced waveguiding effect is observed, which is interesting for further detection applications.

Abstract

We study numerically by a Finite Element Modeling (FEM) approach the design and the optimization of a Love wave transducer coated with a mesoporous sensitive layer. This association could allow to realize an easy functionalizable transducer for biochemical detection in liquid medium. The FEM approach is a good way to design the transducer by estimating many physical parameters in order to obtain a device which could work properly for a given application. Especially, by using a porous layer coated on an acoustic Love wave transducer, we need to be sure that the propagation parameters are still compatible with a usable device. In this paper, after a description of the reduced finite element model of the Love wave transducer, we show that the first experimental results are in a good agreement with the simulations. An “ultra-reduced” FEM approach of the Love wave transducer is carried out for easier consideration of the porous sensitive coating. Finally, experimental transducers are coated with TiO 2 porous sensitive layers by the sol gel technique: the porosity is varied in the range from 10% to 25 %, the pore size from 10 nm to 200 nm, and the thickness from 100 nm to 500 nm. Simulated and experimental results are in good accordance, and allow us to conclude that such transducer could achieve a good propagation of the acoustic wave for biochemical sensing.
