The Recent Progress on Halide Perovskite-Based Self-Powered Sensors Enabled by Piezoelectric and Triboelectric Effects

Sensors have recently gathered significant attention owing to the rapid growth of Internet Things (IoT) technology for real-time monitoring surroundings and human activities. Particularly, discovered nanogenerator-based self-powered sensors are potential candidates overcome existing problems conventional sensors, including regular monitoring, lifetime a power unit, portability. Halide perovskites (HPs), with an excellent photoactive nature, dielectric, piezoelectric, ferroelectric, pyroelectric properties, been obtaining flexible light, pressure, temperature. Additionally, photo-stimulated triboelectric properties HPs make them efficient entrants developing bimodal multimode sense multi-physical signals individually or simultaneously. Therefore, we provide update on recent progress in based pyroelectric, effects HP materials. First, detailed working mechanism HP-based triboelectric, nanogenerators—operated as sensors—is presented. effect light piezoelectric HPs, which is indispensable sensor application, also systematically discussed. Furthermore, advances comprising light-active materials summarized. Finally, perspectives continuing challenges presented some opportunities future development sensors.
