Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A catheter includes an electromechanical polymer (EMP) actuator disposed in a steerable tip at the distal end of the catheter. When activated, the EMP actuator deflects the steerable tip through an angle between 0 and 270 degrees, thus permitting the operator to steer the steerable tip through the vasculature. The steerable tip also has at least a first relatively stiff region and a second relatively flexible region, and the EMP actuator is provided next to the first relatively stiff region so that the steerable tip may toward the flexible region when activated. In one implementation, an external interface allows a user to select by name one of many sets of control signals, with each set of control signals being signals calibrated for configuring the catheter to mimic a known catheter.

Abstract: Electromechanical polymer (EMP) actuators are used to create haptic effects on a user interface deface, such as a keyboard. The keys of the keyboard may be embossed in a top layer to provide better key definition and to house the EMP actuator. Specifically, an EMP actuator is housed inside an embossed graphic layer that covers a key of the keyboard. Such a keyboard has a significant user interface value. For example, the embossed key provides the tactile effect of the presence of a key with edges, while allowing for the localized control of haptic vibrations. For such applications, an EMP transducer provides high strains, vibrations or both under control of an electric field. Furthermore, the EMP transducer can generate strong vibrations. When the frequency of the vibrations falls within the acoustic range, the EMP transducer can generate audible sound, thereby functioning as an audio speaker.

Abstract: 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.
