Pressure detection system for electric wire

Abstract

A pressure detection system for electric wire that can continuously monitor application of pressure to an electric wire. A pressure detection system for an electric wire includes: a sensor unit including a tape-shaped substrate made of an elastic dielectric material, and conductive coating layers provided on both surfaces of the substrate; a detection unit configured to measure characteristic impedance between the two coating layers constituting the sensor unit; and a recording unit configured to record a history of a change in the characteristic impedance measured by the detection unit, wherein the sensor unit is disposed on an outer periphery of an electric wire in such a manner that one of the coating layers extends along a surface of the electric wire.
