Electrospun Elastomeric Nanofibers Enabled Advanced Flexible Wearable Self‐Powered Integrated Sensors: A Review

Abstract Self‐powered elastomeric fiber‐based sensors have been widely applied in the fields of smart wearables and beyond, due to their flexibility and lack of need for an external power source. This review summarizes the recent research progress on wearable self‐powered integrated sensors based on elastomeric fiber substrates, providing a detailed description of their fabrication methods, working principles, and applications. Based on their composition and working principles, the self‐powered integrated sensing systems include energy harvester devices, energy storage devices, sensors, and integrated systems, respectively. An overview of their applications in the fields of biophysical signal detection, electrophysiological signal detection, and human‐machine interaction is also provided. By integrating self‐powered technology with sensing, data processing, wireless transmission, and other functions, a self‐powered wearable sensing system that can monitor, analyze, and transmit data in real time has been developed, providing a more comprehensive solution for personalized medicine and health management. Additionally, the current challenges and future perspectives of self‐powered integrated sensors are also proposed.
