The system includes at least one internal battery located in the prosthetic arm, at least one external battery connected to the prosthetic arm, and a master controller configured to connect either the at least one internal battery or the at least one external battery to a power bus to power the prosthetic arm.

A nerve in a mammal is optogenetically transduced, wherein the nerve is susceptible to stimulus by selective application of transdermal light, and a light source is applied to dermis of the mammal at or proximate to the optogenetically transduced nerve, to thereby stimulate the nerve. A wearable device for optogenetic motor control and sensation restoration of a mammal includes a wearable support, a power source at the wearable support, a controller at the wearable support and in electrical communication with a power source, and a transdermal light source coupled to the controller.

A prosthetic arm apparatus including a plurality of segments that provide a user of the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connectable to one another and connectable to a prosthetic support apparatus that may be adorned by the user. Each segment of the plurality of segments provides a portion of the movement capability, enabling the plurality of connected segments connected to the harness mount to provide substantially the same movement capability as that lacking in the user.

A prosthetic arm apparatus including a plurality of segments that provide a user of the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connectable to one another and connectable to a prosthetic support apparatus that may be adorned by the user. Some segments may provide movement about more than one axis using a single actuator. The prosthetic arm apparatus may include a user interface incorporated therein and may include one or more communication systems for communicating with external devices.

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.

A prosthetic arm apparatus including a plurality of segments that provide a user of the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connectable to one another and connectable to a prosthetic support apparatus that may be adorned by the user. A prosthetic limb segment includes a housing having an input interface and an output interface, the output interface and the input interface being moveable with respect to one another, a motorized drive disposed within the housing, the motorized drive effecting movement of at least one of the output interface or the input interface, and a controller disposed within the housing for controlling actuation of the motorized drive. The controller may be configured to communicate with at least a second motorized drive of at least a second prosthetic limb segment to control actuation thereof.

A system for powering a prosthetic arm is disclosed. The system includes at least one internal battery located in the prosthetic arm, at least one external battery connected to the prosthetic arm, and a master controller configured to connect either the at least one internal battery or the at least one external battery to a power bus to power the prosthetic arm.

High resolution active matrix nanowire circuits enable a flexible platform for artificial electronic skin having pressure sensing capability. Comb-like interdigitated nanostructures extending vertically from a pair of opposing, flexible assemblies facilitate pressure sensing via changes in resistance caused by varying the extent of contact among the interdigitated nanostructures. Electrically isolated arrays of vertically extending, electrically conductive nanowires or nanofins are formed from a doped, electrically conductive layer, each of the arrays being electrically connected to a transistor in an array of transistors. The nanowires or nanofins are interdigitated with further electrically conductive nanowires or nanofins mounted to a flexible handle.
