An estimated 1.7 million people in the U.S do not have a limb, according to Rice University in Houston. While existing prosthetics allow amputees to regain some of their abilities, there are very few devices that provide sensory feedback for the users. Researchers from Rice University, the University of Pisa and the Italian Institute of Technology are working to allow amputees to better perceive what their prosthesis is doing. VOA's Elizabeth Lee reports from Houston.
