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.

Methods and systems to interface between physiological devices and a prosthetic device, including to receive a plurality of types of physiological activity signals from a user, decode a user movement intent from each of the plurality of signals types, and fuse the movement intents into a joint decision to control moveable elements of the prosthetic device.

Certain embodiments are directed to mechanical devices for augmenting dexterous reach and sensing of a user. The devices can include a proximal portion configured to receive an appendage of a user; a distal portion configured detect sensory information; an articulation positioned between the proximal and distal portion to provide for motion of the distal portion via manipulation of the proximal portion; wherein the distal portion comprising a sensing element and the proximal portion comprises a feedback element, the feedback element being connected to the sensing element providing for physical extension of sensory capabilities of the appendage.

Electronic assistive gloves for covering artificial prosthetic or robotic hands. The glove includes a base layer formed to fit on the artificial hand, a plurality of sensors carried by the base layer, and an encapsulation layer covering the base layer and formed of a material that mimics human skin.

Methods and systems for assisting hemiplegic and hemiparetic patients are described herein. A wearable gripper system assists a user with one functional hand to independently perform basic tasks. A wearable gripper is located on the forearm above a disabled hand. The user controls the wearable gripper easily and intuitively based on gestures measured by an instrumented wristband device. Movements detected at the functioning wrist and forearm are translated into the motion control commands communicated to the actuators of the wearable gripper. In this manner, the wearable gripper assists the user to manipulate objects in lieu of the disabled hand. In some embodiments, a number of conductive, stretchable string sensors are wrapped around the hand of a user to estimate wrist and hand motion. In some embodiments, a gripper actuator includes two or more fingers, each having a location dependent shape profile and compliance to accommodate different manipulation tasks.
