Development of a Multifunctional Cosmetic Prosthetic Hand

An innovative artificial hand is presented, which can help to restore both motor and sensory capabilities of upper extremity amputees. All requisite components of the revolutionary prosthesis fit into the small volume of the metacarpus. A new high-power actuating technology has been developed for maximizing the benefit in using the prosthetic hand by increasing the number of grasping patterns. An optional sensory feedback system has been designed for the prosthesis, which is based on mechanical vibration. First clinical trials with the prosthetic hand revealed a high acceptance, as the force necessary to hold an object securely was reduced significantly.
