LIVERMORE, Calif. – The Defense Advanced Research Projects Agency (link is external) (DARPA) recently selected Lawrence Livermore National Laboratory (LLNL) to join a collaborative research team that intends to build the world’s first neural system to enable naturalistic feeling and movements in prosthetic hands.
Known as Hand Proprioception and Touch Interfaces (link is external) (HAPTIX), the program seeks to provide wounded service members with dexterous control over advanced prosthetic devices that substitute for amputated hands. If successful, HAPTIX intends to give patients the psychological benefit of having natural sensation in their prosthetic hands and reduction of “phantom limb” pain, a sensation some amputees can feel despite the removal of a limb.
Lawrence Livermore’s Neural Tech Group and their collaborators (Case Western Reserve University and the Louis Stokes Cleveland Veterans Administration Medical Center) intend to develop neural interface systems that measure and decode motor signals recorded in peripheral nerves and muscles in the forearm by using tiny electrodes.
“The HAPTIX project intends to achieve a phenomenal breakthrough in prosthetics never thought possible,” LLNL’s project leader Sat Pannu said. “Its neural system intends to re-create a range of functions, including a real feeling of touch when holding another person’s hand.”
