Abstract

Abstract : With the growing concern about the safety of the spaces where people work and live, the development of fast and accurate real‐time safety monitoring systems such as gas sensors to detect harmful gas such as H2 S, NH3, and NO x is essential. For effective monitoring, a wireless sensor system that can be used anytime, anywhere is required, but there is still a limit to the power supply to operate it. Self‐powered gas sensors with piezoelectric/triboelectric nanogenerators (PENGs/TENGs) are receiving considerable attention because they can implement portable gas sensors that do not require an additional power source. Herein, the latest developments in piezoelectric/triboelectric effect based self‐powered gas sensors are summarized and discussed. The first part of this review discusses the fundamental aspects and strategies of the self‐powered active gas sensor based on the piezoelectric and triboelectric effects. The second part focuses on the self‐powered gas sensors that operate on energy generated by piezoelectric and TENGs. Abstract : In recent years, a sustainable gas sensor system that can detect the gas environment without an external power source to activate the gas sensor has attracted a lot of interest. Herein, recent progress in piezoelectric nanogenerator and triboelectric nanogenerator‐based self‐powered active or self‐powered gas sensor is discussed and summarized.
