摘要：
A wirelessly controllable device comprises responsive material actuator elements, each driven by a respective receiver circuit having an inductive coil for receiving electrical energy inductively. Each circuit has a different respective resonance frequency. This allows for wireless selective activation of the actuators by applying a magnetic field having frequency components matching the circuits of only those actuator elements which are desired to be activated. A system is further provided, comprising a wirelessly controllable device and a control unit, the control unit having a transmitting inductive coil arrangement for supplying electrical energy to circuits of the wireless device by inductive coupling. A frequency spectrum of the applied field is configured to control which of the actuator elements are activated.
