Abstract
The device includes an energy harvesting module with a pendular unit formed of an elastically deformable piezoelectric beam associated with an inertial mass. A multifunction part includes an axial through-recess with inner bearing surfaces opposite respective outer faces of the beam. These bearing surfaces having an increasing transverse spacing, such as, during an oscillation cycle, the beam comes into contact with one of the bearing surfaces, hence reducing the free length of the beam as the bending of the latter goes along. The multifunction part also allows rationalizing the manufacturing and the assembly of the capsule, with high-level integration of the inner components of the implant.
