CHARACTERIZING AVERAGE HARVESTED ENERGY

摘要

Ambient-energy sources include light, heat differentials, mechanical vibration, transmitted RF signals, or any other source that can produce an electrical charge through a transducer. These energy sources are all around us, and you can convert them into electrical energy by using a suitable transducer, such as a thermoelectric generator for temperature differential, a piezoelectric element for vibration, a photovoltaic cell for sunlight or indoor lighting, and even galvanic energy from moisture. You can use these so-called free energy sources to autonomously power electronic components and systems.
