All-polymer piezoeelctret energy harvester with embedded PEDOT electrode

A novel all-polymer high-aspect-ratio piezoelectret energy harvester with embedded PEDOT electrode is proposed, and its performance for low-resonant-frequency in-plane vibration energy harvesting is demonstrated. Butterfly-shaped stop valves is devised to control the PEDOT capillary flow inside the parylene channels. With the present early prototype, 5.2 V open circuit voltage and 53 nW output power have been obtained at the resonant frequency of 205 Hz with 3.0 g acceleration.
