Moisture-powered, multifunctional flexible sensing systems

Nanowerk - Mon, 08/12/2019 - 5:38am
Researchers demonstrate the feasibility of an environmental moisture-induced, self-powered wearable multifunctional sensing system with the ability to detect both humidity and pressure. The self-powered wearable sensing system is fabricated by integrating a flexible micropatterned pressure-sensitive film on PET as the pressure sensor and attached it onto the back of a PDA power generator. Test results prove that this moisture-powered sensor can stably and sensitively realize real-time human physiological signal detection.
