Abstract
An intracorporeal capsule for placement in a heart and for energy harvesting using blood pressure variations is shown and described. The capsule includes a capsule body and a piezoelectric strip coupled to a rigid surface for receiving blood pressure force. The piezoelectric strip is normally perpendicular to the direction of the force on the rigid surface. The piezoelectric strip is disconnected from the capsule body along at least two edges of the piezoelectric strip such that the blood pressure force can move the rigid surface, and thereby deform the piezoelectric strip for energy harvesting.
