Abstract

Abstract Triboelectric nanogenerators (TENGs) combine contact electrification and electrostatic induction effects to convert waste mechanical energy into electrical energy. As conventional devices contribute to electronic waste, TENGs based on ecofriendly and biocompatible materials have been developed for various energy applications. Owing to the abundance, accessibility, low cost, and biodegradability of biowaste (BW), recycling these materials has gained considerable attention as a green approach for fabricating TENGs. This review provides a detailed overview of BW materials, processing techniques for BW‐based TENGs (BW‐TENGs), and potential applications of BW‐TENGs in emerging bioelectronics. In particular, recent progress in material design, fabrication methods, and biomechanical and environmental energy‐harvesting performance is discussed. This review is aimed at promoting the continued development of BW‐TENGs and their adoption for sustainable energy‐harvesting applications in the field of bioelectronics.

Abstract

In this work, a bilayered ultra responsive self-healable photodetector that can restore both its structure as well as sensing property after deformation has been reported. This photodetector is based on ferrite with ultrafast sensing ability along with restoration property. In this dual-layered structure, the upper layer is Ni0.2Zn0.8Fe2O4 (NZF) prepared by citrate gel method and acts as sensing layer, whereas, the lower layer is Urea-Formaldehyde (U-F) microcapsules with flaxseed oil and NZF core. Here bottom layer acts as a healing layer, which can successfully restore film sensing property after deformation. Flaxseed oil acts as a medium to transport NZF from lower layer to the upper sensing area, which was deformed manually. The evaluated photoresponse and recovery time of NZF before deformation are 1.74 sec and 3.28 sec at 100 mW/cm2 respectively, whereas, response and recovery after healing were 1.75 sec and 2.84 sec respectively. The solar light photodetector based on microcapsule that can restore its sensing property ∼98.5%. The purpose of this work is to develop a method by which anyone can fabricate the different types of self-healable solar light photodetector.
