Title:
PIEZOELECTRIC COAXIAL SENSOR
Document Type and Number:
WIPO Patent Application WO/2021/182209
Kind Code:
A1
Abstract:
A piezoelectric coaxial sensor (1) comprises: a sensor body (10) including a sensor unit (S) having a linear central conductor (11), a polymer piezoelectric layer (12) that covers the outer peripheral surface of the central conductor (11), and a first outer conductor (13) surrounding the outer peripheral surface of the polymer piezoelectric layer (12), and at least one jacket layer having a tape-shaped film that is wound so as to surround the outer peripheral surface of the sensor unit (S) and is adhesively bonded by an adhesive layer to a member in contact with the adhesive layer; and a pair of exterior sheets (20, 30), wherein at least one of the pair of exterior sheets (20, 30) has an adhesive layer (22, 32) on one main surface (20S, 30S) side, and in the pair of exterior sheets (20, 30), the main surface (20S, 30S) sides face each other, sandwich at least a part of the sensor body (10), are bonded thereto by the adhesive layers (22, 32), and surround the outer peripheral surface of at least a part of the sensor body (10).
