Abstract
An energy harvester converts into electrical energy the external stresses applied to the implant at the rhythm of the heartbeats. This harvester comprises an inertial unit. A transducer provides an oscillating electrical signal that is rectified and regulated, for powering the implant and/or charging a battery. The instantaneous variations of this electrical signal between two heartbeats are analyzed inside successive time windows, to derive therefrom a physiological parameter and/or a physical activity parameter of the patient with the implant, in particular as a function of a peak of amplitude of the first oscillation of the electrical signal, and of the level of this signal after the bounce phase of the signal oscillation.
