Energy harvesting is the process of collecting ambient energy from sources such as heat, light, electromagnetic radiation and vibration, which are usually wasted, and converts it into electric energy which can be used by portable power electric devices without the use of batteries. This process is also known as power scavenging or energy scavenging.
During the energy harvesting process, a transducer is used to change ambient energy into electric energy. The amount of energy produced is low and so it is used in low-power devices such as mobile phones, wristwatches, wireless sensor nodes and so on. The technology allows electronic products to work as contactless charging devices that make products reliable and efficient.
The energy harvesting market can be segmented by technology, by application and by geography.
Technologies include thermomagnetic, thermoelectric, light energy harvesting, fluid, motion, vibration, bio energy harvesting, RF and so on. Light energy harvesting dominates the market due to the availability of large amounts of solar energy. Applications include; home automation, consumer electronics, aerospace, construction, military, bicycle dynamos and so on. Consumer electronics is the largest application segment.
