Title:
POWER GENERATION DEVICE AND ELECTRIC APPARATUS PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2017/014003
Kind Code:
A1
Abstract:
A power generation module (10) is provided with: a movable unit (60) that is displaced corresponding to an external force (F); a piezoelectric element (1) that generates power by being deformed corresponding to the displacement of the movable unit (60); a control unit (71) that is configured to limit the displacement of the movable unit (60); and a load switch (31). The load switch (31) is connected in series between the piezoelectric element (1) and output nodes (T1, T2), and is configured to be electrically connected when the displacement quantity of the movable unit (60) reaches a displacement quantity to be limited by the control unit (71).
