Document Type and Number:
WIPO Patent Application WO/2018/230269
Kind Code:
A1
Abstract:
Provided is a monitoring sensor that has improved sensor sensitivity. A monitoring sensor 5 that has: a polymer matrix layer 3 that contains a magnetic filler, has an elastic modulus of 0.1–40 MPa, and deforms in accordance with changes in the state of a monitored object; a magnetic sensor 4 that detects changes in a magnetic field that occur in association with the deformation of the polymer matrix layer 3; and a first yoke 60 that is arranged on a back side of the magnetic sensor 4 as seen from the polymer matrix layer 3.
