Longtime APL collaborator Johnny Matheny and APL engineers Luke Osborn and Rama Venkatasubramanian detail their journey to restore cold sensation in phantom limbs and prosthetics using a new APL-developed thermoelectric cooling device.

Laboratory Restores Cold Sensation in Amputees’ Phantom Limbs

Johns Hopkins APL researchers have developed one of the world’s smallest, most intense refrigeration devices. The adhesive bandage-like device mimics the body’s natural and rapid ability to sense temperature, and bioengineers at the Lab are now using it to help amputees perceive a sense of cold in their phantom limbs.
