Abstract
An apparatus for energy conversion, comprising a piezoelectric component comprising a first part configured to convert vibrational energy into electrical energy; and an output for sending a first portion of the generated electrical energy to an electronic device, and a feedback loop for feeding a second portion of the generated electrical energy to a second part of the piezoelectric component, wherein the second part of the piezoelectric component is coupled to the first part of the piezoelectric component and is configured to convert electrical energy into vibrational energy thereby causing the first part of the piezoelectric component to vibrate.
