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.

A stretchable electronic device for artificial skin and a method of manufacturing the same are disclosed. The stretchable electronic device for artificial skin includes a first encapsulation layer, a heater disposed on the first encapsulation layer, a second encapsulation layer disposed on the heater, a first sensor array layer disposed on the second encapsulation layer, and a third encapsulation layer disposed on the first sensor array layer.

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.

Systems and method utilizing microelectronic devices for determining relative positions such as distances and/or angles between at least two points is described. The points may be locations of parts of the body such as the fingers on a person's hand. A first microelectronic device is adapted to emit magnetic signals and at least one second microelectronic device is adapted to receive the magnetic signals, wherein a controller is adapted to communicate with the first and second microelectronic devices. The second microelectronic device and/or the controller are adapted to determine a distance and angle between the first and the second microelectronic devices based on the strength of the magnetic signals received by the second microelectronic device.
