Impulse-Excited Energy Harvester based on Potassium-Ion- Electret

[摘要] We have developed an energy harvester that is specifically desired for impulse acceleration of infrastructure vibrations such as sudden motion at railway bridges. The energy harvester based on potassium-ion-electret on the sidewalls of 1.8- μm-gap comb electrodes generated a 64 μAp-pcurrent during low impulse acceleration, which was large enough to light a green LED.
