PURPOSE: An energy collecting device between a human body and an environment is provided to simultaneously use photoelectric, piezoelectric, and thermoelectric effects, thereby increasing energy collecting efficiency. CONSTITUTION: A photoelectric energy converting unit(110) receives solar light and converts the solar light into electrical energy. A piezoelectric energy converting unit(120) converts a change of pressure due to movement of a human body into electrical energy. A thermoelectric energy converting unit detects an external temperature and a human body temperature using a thermoelectric element. The thermoelectric energy converting unit converts the difference between the human body temperature and the external temperature into electrical energy. An energy storing device receives and stores electrical energy from the photoelectric energy converting unit, the photoelectric energy converting unit, and the thermoelectric energy converting unit. |
