Title:
PIEZOELECTRIC COAXIAL SENSOR
Document Type and Number:
WIPO Patent Application WO/2021/182210
Kind Code:
A1
Abstract:
A piezoelectric coaxial sensor (1) is provided with: a central conductor (11) comprising a conductive wire; a polymer piezoelectric body layer (12) coating an outer peripheral surface of the central conductor (11); a first external conductor (13) surrounding the outer peripheral surface of the polymer piezoelectric body layer (12); a first jacket layer (14) coating an outer peripheral surface of the first external conductor (13); and a second external conductor (15) surrounding an outer peripheral surface of the first jacket layer (14). A voltage results between the central conductor (11) and the first external conductor (13) due to induced charge produced in the polymer piezoelectric body layer (12).
