Development of a prosthetic hand with a built-in heating device to prevent residual limb pain for upper limb amputee

This paper introduces a prosthetic hand with a built-in heating device to prevent residual limb pain of upper limb amputee. The heating device consists of a heating pad for efficient heat transfer, a heating control switch that can be adjusted according to the sensation of the affected part, a battery charge interface, and a temperature sensor to determine the internal heating condition. The prosthetic hand is composed of a normal hand-shaped silicone outer skin and inner skin with a built-in heating device. And the manufacturing process using these is shown. Its internal temperature and usage time test were performed according to the heating switch setting.
