Schematic of targeted transcutaneous electrical nerve stimulation on the residual limb of an amputee for sensory feedback to the phantom limb. Multiple peripheral nerve sites can be stimulated on an amputee to elicit activation of specific regions of the phantom hand. Sensor outputs from a prosthetic hand can be mapped to specific nerve stimulation sites and a neuromorphic tactile signal used to drive stimulation for closed-loop sensory feedback for amputees.
