Pressure transducers incorporated in the sole of the artificial foot respond proportionately to pressure on individual areas of the foot and send tingling signals to the amputee's residual limb. The more pressure exerted on the artificial foot, the greater the magnitude of the sensation in the residual limb. The brain is given sensory information from the artificial foot in relation to pressure from the floor . Amputees may feel their foot in such non-ambulatory activities, such as pushing an automobile clutch, brake or bicycle pedals. Early indications suggest that the system may result in a significant reduction of phantom pain.
Some amputees are able to feel the foot and lower leg as if it was actually reconnected to the body.
The phenomenon is called cerebral projection, in which the brain projects the missing feedback in the patient's mind. Temperature sensors placed in the prosthetic hand respond to the hot and cold environment. The sensors send signals to a computerized advanced circuitry system which interprets these signals. The circuitry system then sends the signal to electrodes on the skin of the patient. These electrodes relay the sensation of hot or cold directly to the patients residual limb.
