  • Dielectric elastomer drive sensor system and sheet
    Patent number: 11213133
    Abstract: A dielectric elastomer driving sensor system includes: a dielectric elastomer transducer portion including a dielectric elastomer layer and a pair of electrode layers that sandwich the dielectric elastomer layer, where the pair of electrode layers include a driving region and a sensor region that are partitioned from each other; a power supply unit that applies a voltage to the driving region; a detection unit that detects a change in capacitance in the sensor region; and a control unit that controls the power supply unit and the detection unit. With this configuration, both the driving function and the sensor function can be performed.
    Type: Grant
