Document Type and Number:
WIPO Patent Application WO/2020/017068
Kind Code:
A1
Abstract:
This sensor device includes: a core using a core material for which residual strain after 2% elongation is no more than 0.4%; a conductor that has an electrical resistance value of no more than 1kΩ/m and that is wound around the outer circumferential part of the core in a coil shape; a sensor member that has an electromagnetic wave shielding layer which shields the conductor from external electromagnetic waves; and a measuring means for detecting electrical signals from the sensor member and for measuring displacement of the sensor member on the basis of changes in the electrical signals.
