Sources
- photovoltaic
- electrodynamic
- piezoelectric
- thermoelectric
Energy can be captured from:
- linear motion
- solar
- thermal
- vibrations
- rotation
- radiowaves
- air pressure changes
- muscle contraction
- blood sugar fuel cells
- organic material
How does it work?
First the source is selected considering the best way in specific case in example photovoltaics(PV) in very sunny place etc. After or during the energy harvesting(EH) the energy which is harvested from the source will be conversed to electricity and stored to suitable store (capacitor, rechargeable battery) or used instantly.
