    摘要： The invention relates to a device for opening and closing an opening (11), especially on a vehicle, by means of a motor-driven, mobile element (10). The inventive device comprises a control unit (26) and an anti-pinch sensor (14) that is substantially disposed along an edge (20) of the element (10) and/or the frame profile (12) limiting the opening (11) and that detects an obstacle (24) in the path of adjustment of the element (10) when the element (10) is closed, and that forwards a signal to the control unit (26) to stop or reverse the movement of the element (10). Said anti-pinch sensor (14) comprises a highly elastic electroactive polymer (EAP) material (30), especially polyurethane, fluoroelastomer, polybutadiene, fluorosilicone or silicone disposed between the electrodes (28, 34, 36) and effecting a change in voltage o the electrodes (28, 34, 36) when deformed.

    摘要： A suspended-load backpack designed to permit the load to move relative to the backpack frame during walking and running so that the large movements between the load and the frame of the backpack reduce the fluctuations of absolute vertical motion of the load. Because the hip (and thus the pack frame) go up a down a good deal during walking, a large relative movement between the frame and the load reduces the absolute excursion of the load. This movement may be, in turn, transferred to a motor through, for example, a rack and pinion gear, to convert the mechanical movement to electrical energy. The movement may also be converted to electrical energy by using an electroactive polymer (EAP) to connect the suspended load to the frame. Such designs allow the load to move in a controlled fashion to prevent the patient from losing his or her balance as the load moves up and down along the backpack frame. Such movement of thesuspended-load relative to the frame also reduces the forces on the wearer's shoulders while walking or running, thus reducing the likelihood of orthopedic injury.

    摘要： A sheet-form piezoelectric device having improved mechanical strengths as represented by an electrode peel strength while retaining flexibility and piezoelectric performances of a polymer-type piezoelectric device, is obtained by embedding a perforated sheet electrode into at least one surface layer of a polymer piezoelectric film treated with a solvent in advance. The sheet-form piezoelectric device may be wound or curved about a certain central axis to provide a tubular or curved piezoelectric device having wave-transmitting and/or -receiving characteristics suitable for wave-transmitting and/or -receiving devices, such as a hydrophone and microphone.

    摘要： The invention relates to a piezoelectric element comprising a piezoelectric material 1, in the form of a polymer network, between at least two electrodes 2, 3. The piezoelectric material is formed from a starring material comprising a liquid crystalline monomeric material and a chiral compound. The starting material is brought to a temperature at which a smectic phase is formed, and an electric field is applied to obtain a dipolar orientation in the starting material, after which the polymer network is formed by means of photopolymerisation. The piezoelectric element thus manufactured can suitably be used for various electromechanical applications, as a sensor material, for pyroelectric applications and, in particular, also for optical applications.
