Prosthetic News and Research

RSS

Prosthetic (Prosthesis) devices, such as an artificial leg, that replace a part of the body. Prostheses are typically used to replace parts lost by injury (traumatic) or missing from birth (congenital) or to supplement defective body parts. Inside the body, artificial heart valves are in common use with artificial hearts and lungs seeing less common use but under active technology development. Other medical devices and aids that can be considered prosthetics include artificial eyes, palatal obturator, gastric bands, and dentures.

Amputees regain temperature sensation with new prosthetic technology

Sensory feedback is important for amputees to be able to explore and interact with their environment. Now, researchers have developed a device that allows amputees to sense and respond to temperature by delivering thermal information from the prosthesis' fingertip to the amputee's residual limb.
