BEND SENSOR

摘要

Provided is a bend sensor obtained by sandwiching a polymer electrolyte film between a pair of electrode films, the electrode films containing electroconductive particles and a block copolymer (Z) having a polymer block (S) having an ion-conductive group and comprising structural units derived from an aromatic vinyl compound, and an amorphous polymer block (T) comprising structural units derived from an unsaturated aliphatic hydrocarbon, and the block copolymer (Z) having a sensor part in which a lamellar structure is formed, whereby a voltage generated across the electrode films when the bend sensor deforms to follow movement of an object is increased.
