IMPLANTABLE DEVICE AND CONTROL METHOD

An implantable device includes an EAP actuator and a sensor. The sensor is configured to monitor a force external to the implantable device acting in a direction either with or counter to a direction of actuation of the actuator, and a controller is adapted to control the actuator to actuate at a mo...

Zusammenfassung:	An implantable device includes an EAP actuator and a sensor. The sensor is configured to monitor a force external to the implantable device acting in a direction either with or counter to a direction of actuation of the actuator, and a controller is adapted to control the actuator to actuate at a moment when force counter to the direction of actuation is sensed to be at its lowest within a given time window or force with the direction of actuation is sensed to be at its highest within a given time window. In this way, actuation is effected at a moment of least resistance force, reducing the power needed for deployment of the actuator, and permitting actuation to occur even in conditions experiencing large variable forces.
