Abstract
An energy harvester converts into electrical energy the external stresses applied to the implant at the heartbeat rhythm. This harvester comprises an inertial unit and a transducer delivering an electrical signal that is rectified and regulated for powering the implant and charging an energy storage component. The charge level of the energy storage component is compared with a lower threshold to detect an insufficient charge, and a dynamic charging control circuit modifies, as and whenever necessary, and if the current patient's state allows it, a stimulation parameter in a direction liable to increase in return the mean level of the mechanical energy that is produced and harvested.
