A deformation detecting sensor for a sealed secondary battery of the present invention is used with a unit cell, battery module, or battery pack of the sealed secondary battery and includes: a magnetic resin layer stuck to the unit cell and/or battery module, the resin layer comprising a matrix composed of a resin component and a magnetic filler dispersed in the matrix; and a magnetic sensor attached to the inside or outside wall of a package case so as to be capable to detect a change of a magnetic field caused by the magnetic layer. The present invention can provide a deformation detecting sensor capable to detect bulging of a sealed secondary battery with higher sensitivity and to exhibit stable detection characteristics.

Deformation detecting sensor for sealed secondary battery

The present invention provides a sensor including a tactile sensor and bending sensor and a method of making the same, of which the manufacturing cost is low, the production efficiency is high and the sensor sensitivity is improved. The present invention relates to a sensor including a tactile sensor and bending sensor composed of an elastomer containing a magnetic filler and a magnetic sensor that detects a magnetic change caused by deformation of the elastomer; and a method of making the same, of which the viscosity of the mixed solution of the thermosetting elastomer precursor solution with the magnetic filler is adjusted to a specified range.

Sensor and a method of making the same

The present invention provides a sensor having an improved sensitivity and precision, which is lighter and more flexible than conventional sensors, and a method of making the sensor. The present invention relates to a sensor comprising a resin foam containing a magnetic filler, and a magnetic sensor that detects a magnetic change caused by a deformation of the resin foam, wherein the resin foam is a polyurethane resin foam that comprises a polyisocyanate component, an active hydrogen component, a catalyst and a foam stabilizer, and wherein the resin foam has a hardness change (H-H) of 0 to 10 between a JIS-C hardness (H) in one second after contact with a pressure surface of a hardness tester and a JIS-C hardness (H) in 60 seconds after the contact.
