Abstract

Abstract Nowadays, aiming to fight against environmental pollution and energy crisis, a great amount of effort has been performed on self‐powered devices. Herein, assembling a wind‐driven triboelectric nanogenerator (TENG) and a pressure sensitive elastic polyimide (PI)/reduced graphene oxide (rGO) foam together, a self‐powered pressure sensor system has been designed and investigated. Employing Ag nanoparticles and nylon film as electrode and vibration membrane, the TENG can generate desirable output. Meanwhile, the PI/rGO foam acts as the pressure sensitive unit. Integrating a bulk of PI/rGO foam (14 mm × 14 mm × 30 mm), the TENG could generate output voltage and current up to 130 V and 7.5 µA with an effective working area of 100 mm × 15 mm. Additionally, the as‐fabricated device presents various stress sensing scopes and sensitivities, when different heights of foams are integrated on the TENG. The self‐powered pressure sensor achieves a great combination between new clean energy resources and traditional pressure sensor.
