PROBLEM TO BE SOLVED: To provide a sensor which can correctly measure the amount of displacement using a field reactive polymer responsive to an electric field.SOLUTION: In the sensor 100 is constituted of an elastomer film 120 held by two flexible electrodes 140 between and uses the field reactive polymer of which the capacitance varies with an extending-contracting movement, the electric field reactive polymer is stuck to an elastic curing sheet 180, in a state of tension applied thereto. |
