What are vibration-powered generators?

Electricity generated by converting vibrational energy by the mass of people walking or cars moving over it.
Vibration energy is efficiently collected to improve power generation efficiency.
“Vibration-powered generators” are floor based power generation units that produce electricity from the vibrational energy which people and vehicles impart to floors as kinetic energy.

【 Amount of power generated 】
・Approx. 2mW
・ 0.1 to 0.3W (instantaneous maximum value per 1ms under the following conditions*)

* Average in experiments of someone taking two steps per second and who weigh approx.

Mechanism of power generation

The electric power is generated by distortion of “piezoelectric element” installed in the power generation unit.
