    PIEZOELECTRIC ENERGY HARVESTING SYSTEM

    A bendable metal plate (12) is connected to a piezo-electric plate (11) for applying compressive forces. A pocket (H1) is formed at a central part (12c) of the metal plate (12) opposite the piezo-electric plate (11). A force receiving surface (31) moves under influence of an external force, applied to the force receiving surface (31) while a pressure centralizing element (33) is configured to focus a central force exclusively to a center (11c) of the piezo-electric plate (11). The metal plate (12) thus bends to a compressive bending position under the influence of the external force by a combination of the central force on the center (11c) of the piezo-electric plate (11) and edge forces by the pocket structure (13) on the outer edges (12e) of the metal plate (12).
