摘要： A wearable haptic device includes (a) substrate having provided thereon a fastener (e.g., adhesive) for attachment to a user; (b) one or more EMP transducers attached to the substrate, such that a mechanical response in each EMP transducer may provide a haptic response of sufficient magnitude to be felt by the user; and (c) control circuit controlling the vibration frequency, the time of operation and the duration for each activation of the EMP transducer. The wearable haptic device may include a wireless communication circuit (e.g., Bluetooth transceiver) for receiving message from an external device (e.g., smartphone). The control circuit interprets message received and according to the interpreted message provides an electrical stimulus to cause the mechanical response of the EMP transducer. The EMP transducer may also serve as a sensor, such that a mechanical stimulus on the EMP transducer provides an electrical response that is detected by the control circuit.

摘要： A localized multimodal haptic system includes one or more electromechanical polymer (EMP) transducers, each including an EMP layer, such as an electrostrictive polymer active layer. In some applications the EMP transducer may perform an actuator function or a sensor function, or both. The EMP polymer layer has a first surface and a second surface on which one or more electrodes are provided. The EMP layer of the EMP actuator may be 5 microns thick or less. The EMP transducers may provide local haptic response to a local a stimulus. In one application, a touch sensor may be associated with each EMP transducer, such that the haptic event at the touch sensor may be responded to by activating only the associated EMP transducer. Furthermore, the EMP transducer may act as its own touch sensor. A variety of haptic responses may be made available. The EMP transducers may be used in various other applications, such as providing complex surface morphology and audio speakers.

摘要： A motor-less pump includes: (a) a housing having an inlet provided to allow fluid flow into the housing and an outlet provided to allow fluid flow out of the housing; (b) an elastic diaphragm positioned in the housing such that motion in the elastic diaphragm drives the fluid flows at the inlet and the outlet of the housing; and (c) one or more electromechanical polymer (EMP) actuators each being provided on a surface of the elastic diaphragm, wherein the mechanical responses to electrical stimuli applied on the EMP actuators cause the motion in the diaphragm. The EMP actuators may include one or more bimorphs.

摘要： An electromechanical polymer (EMP) transducer may include (a) one or more EMP layers each having a first operating characteristic; and (b) one or more EMP layers each having a second operating characteristic different from the first operating characteristic. The EMP transducer may include at least two EMP layers that are activated independently, and one or more EMP layers being configured to be a sensing layer. The sensing layer may sensitive to one or both of the operating characteristics (e.g., temperature, strain, pressure and their respective rates of change). Other operating characteristic may include resin type, modulus, film thicknesses, degrees of deformations, operating temperature ranges, a stretching ratio of the EMP layers, metallization patterns of electrodes, arrangements of active and inactive EMP layers, arrangements of irradiated EMP layers, arrangements of EMP layers acting as sensors, and arrangements of inactive layers of various degrees of stiffness.

摘要： A housing for an electronic device allows a haptic feedback response that is localized to a specific area on a back panel of the housing of the electronic device. For example, a user holding the mobile electronic device may directly receive haptic feedback in his/her fingers that are supporting the back side of the mobile electronic device. Those specific areas on the back panel may be locations where the panel material is thinned, or locations where the panel material has been removed and replaced by a suitably selected membrane material having favorable mechanical properties. The membrane material may be introduced as an embossment of a membrane layer. In addition, a force-sensing resistor type material may be used as a replacement material, so as to sense the pressure of a user's finger pressing on the embossed structure at the specific locations to which EMP actuators are bonded.

摘要： An inertial actuator includes an electro-active polymer EAP actuator, a substrate, and one or more mass elements. The EAP actuator includes at least one EAP layer located between a pair of driving electrodes. The EAP actuator may include a multilayer stack of alternating EAP layers and electrode layers. The EAP actuator is attached to the substrate (e.g., a flexible polymer substrate), which may be held under tension by attachment points at the periphery of the substrate, at the ends of a beam-type substrate, or the edges of a membrane-type actuator. The EMP actuator induces vibrations in the substrate. One or more mass elements (e.g., metal films) may also be supported by the substrate to enhance the resonator response.
