Small Energie Harvesting
Thermoelectric Energy Harvesting
The Thermoelectric Energy Harvesting is done with the Seebeck effect, one phenomenon of the thermoelectric effect. A Peltier module can be used for that.
Vibration Energy Harvesting
With the piezoelectric effect Vibration Energy Harvesting can be done. Mechanical energy in the form of vibration or shock can be convert into electrical energy in using a piezo module.
I use the Mide PPA 1001 module bought by mouser: https://www.mouser.de/new/Mide-Technology/mide-ppa-piezoelectric-products/
