Title:
圧電部材
Document Type and Number:
Japanese Patent JP7102762
Kind Code:
B2
Abstract:
A piezoelectric body that is excellent in endurance, flexibility and bendability is achieved. A piezoelectric member includes: belt type first and second conductive rubber sheets that face each other; and a piezoelectric layer formed between an upper surface of the first conductive rubber sheet and a lower surface of the second conductive rubber sheet. The piezoelectric layer is made of a piezoelectric coating material with which at least either one of the upper surface of the first conductive rubber sheet and the lower surface of the second conductive rubber sheet is coated. When a pressure is applied to the piezoelectric layer through at least either one of the first conductive rubber sheet and the second conductive rubber sheet, a potential difference is generated between the first conductive rubber sheet and the second conductive rubber sheet.
