Abstract
An energy harvesting module includes a pendular unit with piezoelectric transducer elastically deformable in bending between a clamped end and a free end coupled to an inertial mass. The piezoelectric transducer includes two coplanar piezoelectric beams arranged side-by-side on either side of a central axis of the transducer, each of the piezoelectric beams including adjacent external and internal arms, arranged side-by-side and formed single-piece. The external arm of each beam has a clamped proximal end and a free distal end, and the internal arm of each beam has a free proximal end supporting the inertial mass, and a free distal end connected to the distal end of the adjacent external arm by a common junction.
