Wearable computers or devices have been hailed as the next generation of mobile electronic gadgets, from smart watches to smart glasses to smart pacemakers. For electronics to be worn by a user, they must be light, flexible, and equipped with a power source, which could be a portable, long-lasting battery or no battery at all but a generator.
Energy Harvesting devices can derive energy from a variety of sources including Solar, Vibration, and Temperature variation. By utilizing these natural energy sources, designers can create applications that are maintenance free and allow for implementations that have not before been possible.
