The present invention provides a polymeric actuator which has excellent flexibility and elongation rate; low temperature dependability of physical properties such as an elastic modulus and high dielectric breakdown strength, and which can drive in a low electric field. The present invention relates to a polymeric actuator, wherein the polymeric dielectric has a storage elastic modulus at 20&#xb0; C. [E'(20&#xb0; C.)] determined by a dynamic viscoelastic measurement at a frequency of 1 Hz of not more than 0.5 MPa,

Polymeric actuator

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.
