<p>Loss or absence of sensibility in the hand, foot or other part of the body can constitute a severe handicap after injury or in disease. Also when hand prostheses are used following amputation, injuries lack of sensibility in the prostheses constitutes a major problem. The prevailing invention refers to a new principle for artificial sensibility by sense substitution (replacement of a lost sense function by utilization of an alternate sense). The primary aim is to, by using the hearing sense, achieve sensibility in hand prostheses or hands which have lost their sensibility by injury or disease. According to this principle vibrotactile stimuli to the fingers are registrated by sensors of microphone type, placed at finger level, the signals being processed and transformated into acoustic stimuli. By using this principle the patient can 'feel with the hearing sense' hereby utilizing the hearing sense to register and identify the surface, texture, density and shape of the item which is touched.</p> |
