Guest Editorial Special Issue on Self-Powered Sensors: Architectures, Applications, and Challenges

At present, the sustainability of a sensor becomes a hindrance due to energy storage’s limited lifetime. In this case, self-powered sensors are proposed to solve this issue. While self-powered sensors are promising, there are still some challenges to overcome before they can be deployed on a large scale. Therefore, this Special Issue aims to solicit original papers with discussions on self-powered sensors, as well as their architectures, applications, and challenges.
