A unique worldwide product, which allows amputees to naturally feel their missing limbs.

SENSY is a unique worldwide product, which allows amputees to naturally feel their missing limbs. The device is composed of implantable transversal multi- and intra- fascicular neural electrodes, an implantable neurostimulator, an external controller and a sensor-containing sole. The neuro-stimulator is implanted in the limb and is wired to multi- and intra-fascicular intraneural electrodes that are inserted transversally into the peripheral nerves. Stimulation of sensory nerves is driven wirelessly by an external controller, which transforms the readout of the sensors embedded in the sensor containing sole into stimulation parameters. The sensor-containing sole is adaptable to the prostheses currently available in the market.
