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： 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.

摘要： A retractable snap dome in a keyboard, serving as a force resistor for a key in a conventional manner, includes an additional collapsed state wherein the key can be retracted by an electromechanical polymer (EMP) actuator to a persistent down position. In one embodiment, the EMP actuator is a bimorph EMP actuator that can be actuated to bring the key from down position to up position, ready for conventional keyboard operation, and vice versa. Such operations allow the keyboard to have a desirable decreased thickness relative to conventional keyboards. Thus, a keyboard of the present invention finds application in ultra-slim electronic devices. When provided in a notebook computer wherein the keyboard is folded against a video or graphic display, the keyboard keys may be placed in the retracted down position, thereby preventing the keys from pressing against the video or graphical display with a force that may damage the display.

摘要： A haptic switch includes: (a) a force sensor responding a mechanical stimulus by providing a sensing signal; (b) a processing circuit receiving the sensing signal and providing a control signal; and (c) an electromechanical polymer (EMP) actuator receiving the response control signal and providing a haptic response. The force sensor and the EMP actuator may each be provided on a flexible circuit covered by a protective layer overlying the flexible circuit. The haptic switch may include a graphic layer on which is provided a symbol representing a key. In that haptic switch, the symbol, the light source, the EMP actuator and the force sensor are aligned such that the light source illuminates the symbol and such that, when a user pushes on the symbol, the user's push applies a pressure on the force sensor and the EMP actuator's haptic response is provided in the vicinity of the force sensor.
