Abstract: A system for muscle activity sensing and feedback includes a base textile, an electrode coupled to the base textile, a sensor coupled to the base textile, a controller coupled to the base textile, and a feedback element coupled to the base textile. The feedback element is in communication with the controller. The feedback element receives a feedback signal from the controller and imparts feedback to a user based on an electrical signal from the electrode and/or a sensor signal from the sensor.

Abstract: A thermotactile stimulation prosthesis includes a prosthesis extremity having a prosthesis interface configured for attachment to a human limb, and a thermoelectric actuator array coupled to the prosthesis interface and configured to establish a noninvasive thermoneural human-machine interface capable of providing sensations of temperature to the human limb.

Abstract: A fast-rate thermoelectric device control system includes a fast-rate thermoelectric device, a sensor, and a controller. The fast-rate thermoelectric device includes a thermoelectric actuator array disposed on a wafer, and the thermoelectric actuator array includes a thin-film thermoelectric (TFTE) actuator that generates a heating and/or a cooling effect in response to an electrical current. The sensor is configured to measure a temperature associated with the heating or cooling effect and output a feedback signal indicative of the measured temperature. The controller is in communication with the fast-rate thermoelectric device and the sensor, and is configured to control the electrical current based on the feedback signal.
