Document Type and Number:
Japanese Patent JP6635788
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a technique for further increasing the intensity of a signal of a piezoelectric element by using piezoelectric fiber.SOLUTION: A braid-like piezoelectric element comprises: a core part formed by a conductive fiber; and a sheath part formed by braid-like piezoelectric fiber so as to cover the core part. The braid-like piezoelectric element further comprises a metal terminal fixed and connected to the core part in any of the forms A and B as described below. A) In the form, a fiber portion forming a terminal end of the braid-like piezoelectric element is grasped by part of the metal terminal, and the core part and the metal terminal are electrically connected and fixed to each other within 1 mm from the grasping part. B) In the form, the metal terminal has a portion shaped like a fork or needle, the fork-like or needle-like portion is electrically connected to the core part while touching the sheath part, and the braid-like piezoelectric element is fixed to the metal terminal within 10 mm from the electric connection by another portion of the metal terminal or a component fixed to the metal terminal.SELECTED DRAWING: Figure 2
