Sensory information can be delivered to a subject mammal, for example, for restoring a sense of cutaneous touch and limb motion to the subject mammal. A biomimetic electrical signal is generated based on (a) a stimulation reference signal applied to a somatosensory region of a nervous system of a reference mammal, (b) a stimulated-response signal acquired from a sensory cortex of the reference mammal in response to application of the stimulation reference signal to the thalamic nucleus, and (c) a natural-response signal acquired from the sensory cortex in response to peripheral touch stimuli and/or peripheral nerve stimulation of the reference mammal. The biomimetic electrical signal is applied to a somatosensory region of a nervous system of the subject mammal to induce an activation response, in a sensory cortex of the subject mammal.

A system for conscious sensory feedback for a body extremity without sensation or a body extremity prosthesis is disclosed, as well as methods for conscious sensory feedback based on said system; a glove, a sock and a body extremity prosthesis comprising said system; and use of the system.

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 to 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.

Various aspects of this disclosure relate to a layered polymer substrate with electrodes and conductive ink embedded in the substrate. In some embodiments, a prosthetic liner may be bonded onto the polymer substrate. The substrate may include an interconnect coupled to the electrodes via the conductive ink. The system may include a controller (e.g., an electrode controller) in communication with the electrodes via the conductive ink. The electrodes may be activated such that they may stimulate nerve fibers in a user's residual limb.

A sensory cushioning system, method, and associated apparatus and airbag, an internal electronic assembly, an external electronic assembly, and an interconnect. The airbag forms an interior volume and a pocket, wherein the interior volume is substantially airtight. The internal electronic assembly is positioned within the pocket. The external electronic assembly is positioned exterior to the airbag. The interconnect electrically couples the internal electronic assembly to the external electronic assembly.

A system and method for creation and function of an advanced prosthetic hand includes: a base palm, comprising the primary body of the prosthetic hand; a set of actuating digits, wherein each actuating digit is connected to the palm; a sleeve, connected to the palm, providing an interface; a sensor system, comprising sensors integrated on a subset of the set of actuating digits; and a feedback system, connected to the sensor system enabling sensory feedback from the sensor system. In preferred variations, the base palm comprises, at least partially, a carbon-fiber shell. The system may further include a set of water sealing elements integrated into the prosthetic hand. The system functions as a hand prosthesis with actuating digit and hand components.
