NONUTILITY GENERATION HEATING SEAT CHAIR USING PIEZOELECTRIC HARVESTING

摘要

PURPOSE: A chair with a non-utility generation heating seat using piezoelectric harvesting is provided to convert vibration energy of a chair into electric energy through a piezoelectric element attached on a heating seat, thereby operating the heating seat without separate electric power. CONSTITUTION: A chair with a non-utility generation heating seat comprises: a chair body (104) which enables a user (102) to sit down; a heating seat (110) placed on the surface of the chair body; a piezoelectric element (120) which is placed between the heating seat and the chair body and converts vibration energy into electric energy; a control unit (130) which is electrically connected with the piezoelectric element and commutates the electric energy generated through the piezoelectric element; and a charging unit (140) which stores the commutated electric energy and provides the stored electric energy in the heating seat.
