| Summary: | Stable and repeatable operation is paramount for practical and extensive applications of all energy harvesters. Herein, we develop a new type of flexible piezoelectret generator, which converts mechanical energy into electricity consistently even under harsh environments. Specifically, the generator, with piezoelectric coefficient (d33) reaching ~ 6300 pC/N, had worked stably for continuous ~ 90000 cycles, and the generator pressed by a human hand produced load peak current and power up to ~ 29.6 μA and ~ 0.444 mW, respectively. Moreover, the capability to steadily produce electrical power under extreme moisture and temperature up to 70 oC had been achieved for possible applications in wearable devices and flexible electronics. |
