CLOTH-LIKE PIEZOELECTRIC ELEMENT USING BRAIDED STRING PIEZOELECTRIC ELEMENT AND DEVICE USING THE SAME

Title:

CLOTH-LIKE PIEZOELECTRIC ELEMENT USING BRAIDED STRING PIEZOELECTRIC ELEMENT AND DEVICE USING THE SAME

Document Type and Number:

Japanese Patent JP2018074001

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a cloth-like piezoelectric element capable of taking out a large electric signal by stress generated by a relatively small deformation and using a fibrous piezoelectric element capable of suppressing a noise signal and being easily installed on a base material such as another cloth.SOLUTION: The cloth-like piezoelectric element has a braided string piezoelectric element fixed to a cloth with the braided string piezoelectric element including: a core portion formed of conductive fibers; a sheath portion formed of a braided string piezoelectric fiber so as to cover the core portion; and a conductive layer provided around the sheath portion. The pulling strength per 5 cm of the braided string piezoelectric element with respect to the cloth is 0.1 N or more.SELECTED DRAWING: Figure 3
