Abstract
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.
