What is Energy Harvesting

The process by which energy is derived from external sources, captured and stored
for use in electronic systems

Energy harvesting is the process by which ambient energy is captured and converted
into electricity for small autonomous devices, such as satellites, laptops and nodes in
sensor networks making them self-sufficient.

Where is it useful?



Where line power is unavailable or costly
Where batteries are costly or difficult to replace
Where energy is needed only when ambient energy is present
