<P>PROBLEM TO BE SOLVED: To provide a compact power generation system which efficiently converts kinetic energy such as vibration into electric energy to generate power, without enforcing a user to operate for power generation. <P>SOLUTION: The power generation system includes: a power generation film 14 constituted of a ferroelectric thin film 12 which is curved by kinetic energy and a first electrode 16 and a second electrode 17 formed respectively on the front and rear surfaces of the thin film 12; a rectifying circuit 20 for converting the voltage generated at the first electrode 16 and the second electrode 17 by the curved thin film 12 into direct current; a voltage converter 24 for converting the converted direct voltage into a predetermined voltage; and a power storage means 26 for storing the converted electric charge. <P>COPYRIGHT: (C)2011,JPO&INPIT |
