By brushing your teeth, you can make electricity through piezoelectric element-used self-power generation.
We shake a toothbrush about 700 times when we brush our teeth for about 3 minutes.
When we brush our teeth, kinetic energy is naturally generated and this kinetic energy is stored in the storage battery of the main body of the toothbrush. And the kinetic energy stored in the storage battery is converted into electric energy.
This electric energy operates ‘UV LED, heat rays’ in the toothbrush, which sterilizes it.
The act of brushing teeth plays the functions of sterilization and drying so bacteria can be reduced by 1/50.
