Recent progress of self-powered wearable monitoring systems integrated with microsupercapacitors

Self-powered wearable monitoring systems are considered to be one of the key technologies in the next generation of smart health monitoring system. To realize personal portable devices with mobile electronics applications, wearable monitoring systems that can work sustainably and continuously without an external power supply are highly desired. In this article, the recent progress and advantages of self-powered wearable monitoring systems that are powered by microsupercapacitors (MSCs) for mobile or personal attachable health monitoring applications are presented. Several strategies to get high-performance MSCs are first discussed, followed with an overview of various types of self-powered MSCs-driven wearable sensors, including flexible tactile sensors, wearable image sensor array, biological and chemical sensors, temperature sensors, and multifunctional integrated sensing systems. Finally, the future perspectives of self-powered monitoring systems for wearable electronics are discussed.
