Abstract
Wearable bioelectronics represent a rapidly growing field with significant potential to revolutionize healthcare monitoring, diagnostics, and therapeutics. These devices enable continuous, real-time monitoring of physiological parameters, thus facilitating early disease detection, personalized treatment, and improved health management. Organic semiconductors have emerged as promising materials for these applications due to their flexibility, biocompatibility, and tunable electronic properties, which allow them to conform to the human body and interface seamlessly with biological tissues. This review provides a comprehensive analysis of recent advancements in organic semiconductors for wearable bioelectronics, delving into their fundamental properties, synthesis, and fabrication techniques. It also explores their integration into various wearable devices, including organic thin-film transistors, organic light-emitting diodes, and sensors, highlighting key applications in health monitoring, biosensing, and therapeutic systems. Despite the significant progress made, challenges such as improving stability, ensuring reliable performance under physiological conditions, and scaling up production remain. Addressing these challenges will be crucial for advancing the field and realizing the full potential of organic semiconductors in wearable bioelectronics. • Wearable bioelectronics transforms healthcare monitoring and therapeutics. • Organic semiconductors offer flexibility, biocompatibility, and tunability. • Key advances in properties, synthesis, and fabrication are reviewed. • Applications in transistors, LEDs, and sensors are explored.
