Prototype Generator Harnesses Vibration Power

This is a small prototype generator recently debuted from Omron Corp. It harnesses power from vibrations to create electricity. The model will cost 10.36$ because of its simple structure and packaging.

Omron’s generator works with an “electret power generation system” that changes capacitance depending on the relative position of opposing electrodes. A change in capacitance generates electric current.

The prototype you see in picture above produces only 10μW of power with vibrational inputs at 20Hz frequency and 1G acceleration. This is not enough to fully operate a cell phone.

But despite its minimal generated power there are important uses for this prototype. The generator will be placed in devices installed on highways to detect road problems. The generator could also be installed inside car tires for tire pressure monitoring since tires vibrate strongly during movement.
