Question

How to convert vibration into electricity?

Answer 1

Vibration powered generators usually consist of a resonator which is used to amplify the vibration source, and a transducer mechanism which converts the energy from the vibrations into electrical energy. The transducer usually consists of a magnet and coil or a piezoelectric crystal.

Answer 2

Electromagnetic induction is the basic principle and premise underpinning the conversion of vibrations into electric energy. It refers to the phenomenon when electricity is generated by moving a magnet inside a coil. How then can electromagnetic induction be used to generate electricity from vibrations? The answer lies in the originality of this technology and its development. In reality, a spring plays the role of a power generating unit. Springs, which fulfill several functions including the absorption of shock in a variety of devices, are not only characterized by their ability to extend and contract. Springs also sway when placed in contact with other items that sway, a phenomenon that is referred to as sympathetic vibration. Springs that are in a constant state of sympathetic vibration are fragile. The general consensus, therefore, has been to minimize the sympathetic vibration of machinery as much as possible. MEE, on the other hand, looked toward using this phenomenon to amplify vibrations.
The vibration amplification spring was developed as a result of this approach. This spring exhibits sensitive sympathetic vibration toward external oscillations. Thanks largely to proprietary research into the quality of materials and configuration, there is no danger of the spring breaking despite vibrating continuously for lengthy periods. The vibration amplification spring is used to encircle a magnet and moved fastidiously in an upward and downward motion. This in turn creates electromagnetic induction resulting in electricity. This is the mechanism for vibration power generation utilizing sensor movements.
