Flexible Ionic Diodes for Low‐Frequency Mechanical Energy Harvesting

A novel flexible mechanical-to-electrical energy conversion device is developed based on a p–n organic junction diode architecture. The device produced a power density up to 2 µW cm−3 at an operating frequency of 0.1 Hz, suitable for harvesting mechanical energy from low-frequency sources such as wind, ocean waves, and human motions.
