摘要： The present application relates to a cold plasma device (13) for treating a surface (6) with cold plasma. The device (13) has a cold plasma generator (14) adapted to generate cold plasma that produces reactive species for treating the surface (6). The device (13) also includes a treatment head (5) that is positionable relative to the surface (6) such that the reactive species are imparted toward the surface (6) during treatment. The device (13) is also provided with an air flow generator (8) to generate an air flow over the surface (6) and a controller (9) configured to control operation of the air flow generator (8) to generate an air flow over the surface (6) after the treatment has been completed such that remaining by-products of the cold plasma are dissipated.

摘要： A physiological sensor apparatus offers auto-adjustment of a physiological sensing surface relative to a human tissue receiving surface. The apparatus includes an electroactive polymer (EAP) structure, operable to perform actuation and pressure sensing simultaneously, via application of superposed actuation and AC sensing signals. Actuation enables controlled adjustment of the positioning of a sensing surface against the tissue receiving surface. Sensing provides a simultaneous real-time measure or indication of the magnitude of a returning force applied to the sensing surface by the receiving surface. This returning force provides feedback on the state of positioning of the sensing surface. A controller is adapted to adjust the actuation signal in dependence upon the sensing data, to thereby adjust the positioning of the sensing surface in real-time.

摘要： The proposed device comprises a plurality of electroactive material actuator units (20) arranged as a set. Control data for driving individual units is transferred over three shared power lines (Vop, Vop2, Vref). The electroactive material actuator (21) of each unit (20) is driven depending on control data received from the power lines via a demodulator (24), a controller (26), and a driver (28).

摘要： A field-driven electroactive polymer actuator is provided with a current sensor for sensing a current flowing to the actuator. A control circuit is used for driving the actuator which includes a voltage source. The driving of the actuator is controlled in dependence on the sensed current, thereby to provide a predetermined charge delivery for particular changes in actuation level of the actuator. This provides a combined voltage-based and current-based drive scheme for a voltage-driven EAP actuator, and it enables mechanical movements of the actuator to be more reliably repeated.

摘要： An electroactive polymer actuator comprises an electroactive polymer structure and a driver for providing an actuation drive signal. In one aspect a first drive signal with an overdrive voltage is used to change the charge of the electroactive polymer structure needed for switching the structure from one to another actuation state. When or after the electroactive polymer structure actuation is near or at the another actuation state, a drive voltage is used to bring to and hold the electroactive polymer structure at the actuated state. This temporary overdrive scheme improves the speed response without damaging the electroactive polymer structure.

摘要： An electroactive polymer actuator comprises an electroactive polymer structure and a driver for providing an actuation drive signal. In one aspect a first drive level is used to charge the electroactive polymer structure from a non-actuated state to an actuated state. When or after the electroactive polymer structure reaches the actuated state, a lower second drive level is used to hold the electroactive polymer structure at the actuated state. This temporary overdrive scheme improves the speed response without damaging the electroactive polymer structure. In another aspect, a driving method makes use of several different level segments over time which compensate for the delayed actuation response of the EAP actuator.

摘要： The invention provides an electroactive polymer actuator comprising a capacitance compensation means adapted to at least partially offset any changes in the capacitance across the member induced by its deformation. In this way, the electronic control of the device is rendered much simpler, since a varying capacitance across the actuator member does not have to be accounted for when driving the actuator to perform a particular deformation.

摘要： The invention provides a field-driven electroactive material actuator that is driven by an actuation voltage. A driver is adapted to drive the actuation voltage from a first voltage level to a second voltage level, wherein the second voltage level is lower than the first, by way of a transition function, the transition function occurring over a transition time. The transition function includes a smoothing function. The transition time is at least 0.5 ms.

摘要： An actuator device comprises an electroactive polymer actuator (116) and a control circuit for driving the electroactive polymer actuator. The control circuit comprises a voltage boosting circuit including at least a capacitor (114; C11, C12, C13). An electroactive polymer layer (110) forms the electroactive polymer actuator in an active region (112) as well as a dielectric layer of the capacitor in a passive region (111). This provides integration of components to enable cost reductions and miniaturization.
