Abstract
A system and method are disclosed for providing a piezoelectric electromagnetic hybrid vibrating energy harvester. The invention comprises a piezoelectric vibrating energy harvesting device that harvests electrical energy from vibrations using a piezoelectric effect. The invention also comprises an electromagnetic vibrating energy harvesting device that simultaneously harvests electrical energy from the same vibrations using electromagnetic induction. A permanent magnet mass mounted on a cantilever host beam of the piezoelectric vibrating energy harvesting device provides a variable magnetic flux to a fixed conductive winding of the electromagnetic vibrating energy harvesting device when the permanent magnet mass vibrates.
