The printed electronics (PEs) market has witnessed substantial growth, reaching a valuation of USD 10.47 billion in the previous year. Driven by its extensive use in a multitude of applications, this growth trend is expected to continue with a projected compound annual growth rate of 22.3% from 2022 to 2032. Compared to screen printing, the adoption of inkjet printing (IJP) technology to manufacture PEs has been limited to laboratory‐scale research only. The fact that IJP's inability to maintain consistent high‐resolution quality over large printing areas has made transitioning IJP for commercial production arduous. Most of the previous literatures have focused on holistic discussion on material design for IJP, but this review provides insight into key aspects in material processing up to printing optimization to realize high‐resolution PEs. This review also highlights the challenges in controlling the functional ink properties and their interaction with the substrate as well as printing parameters to deliver the desired quality of the droplets and final prints. Imminent application of IJP in PEs and future perspectives are also included in this review. [ABSTRACT FROM AUTHOR]

Printed sensors have been explored for more than two decades and have now gained significant interest in real-world applications due to low cost, simple and scalable fabrication processes. These sensors must satisfy the requirement of long-term usage as wearable devices, especially for health monitoring and rehabilitation purposes. However, when such devices are continuously worn on the body or implanted within the body, they may cause unexpected risk to the patient's health. To avoid potential health risks, transition to 'green' strategies has already begun in the research, design and manufacturing of these sensors. This review is dedicated to offering a snapshot of current realization and future prospects of printed sensors through green strategies. The utilization of eco-friendly and cost-effective materials for sensor components and the adoption of various printing methods are summarized. The reusability and multi-detection capability of printed sensors that are within the scope of green analytical chemistry are discussed. [ABSTRACT FROM AUTHOR]
