Abstract
Energy harvesting is the process of extracting small amount of energy from environment. Various techniques are being developed to gain electric power from available sources such as wind, vibration, solar, biological, chemical etc. This paper reports the experimental results of unique boiling energy harvester (BEH) which gain the power from kinetic energy of boiling bubbles by means of piezoelectric films. The experimental results indicated that frequency band was broaden with the increase of boiling heat transfer area; and installation of multiple independent piezoelectric films can improve the power generation of BEH.
