Title:
BEARING ASSEMBLY CAPABLE OF GENERATING ELECTRICITY AND BEARING CAPABLE OF GENERATING ELECTRICITY
Document Type and Number:
WIPO Patent Application WO/2019/134065
Kind Code:
A1
Abstract:
Provided is a bearing assembly capable of generating electricity, wherein, the bearing assembly comprises bearing members (10, 20, 30) and a piezoelectric power generator provided at the bearing members (10, 20, 30), and the piezoelectric power generator comprises: a piezoelectric layer (14, 34) provided on the bearing members (10, 20, 30) for generating a charge by bearing the force change of the bearing members (10, 20, 30) when the bearing (100) including the bearing members (10, 20, 30) is operated; a first electrode layer (13, 33) and a second layer (15, 35), the first electrode layer (13, 33) and the second electrode layer (15, 35) are respectively provided on opposite sides of the piezoelectric layer (14, 34) for collecting the charge generated by the piezoelectric layer (14, 34) to extract current; and a circuit board (37) connected to the first electrode layer (13, 33) and the second electrode layer (15, 35) for rectifying the current extracted by the first electrode layer (13, 33) and the second electrode layer (15, 35).
