fiber optic synthetic human nervous system…wow

The Department of Defense and Southern Methodist University have teamed up to develop prostheticsthat use two-way fiber optic communication between artificial limbs and peripheral nerves to essentially give these devices the ability to feel pressure or temperature. The technology is called neurophotonics, and it will someday allow hi-speed communication between the brain and artificial limbs. But that’s just the beginning — the work being done at SMU’s Neurophotonics Research Center might someday lead to brain implants that control tremors, neuro-modulators for chronic pain management, implants for treating spinal cord injuries, and more. And since we can’t have a post about DARPA-funded research without the following trope, Dean Orsak of the SMU Lyle School of Engineering points out that “[s]cience fiction writers have long imagined the day when the understanding and intuition of the human brain could be enhanced by the lightning speed of computing technologies. With this remarkable research initiative, we are truly beginning a journey into the future that will provide immeasurable benefits to humanity.” Truly.

DARPA-funded prosthetic arm reaches phase three, would-be cyborgs celebrate

Last we heard from Johns Hopkins University’s Applied Physics Laboratory, it wanted a neurally-controlled bionic arm by 2009. Needless to say, the school overshot that goal by a tiny bit, and have now been beaten (twice) to the punch. But DARPA sees $34.5 million worth of promise in their third and final prototype, which will enable the nine pound kit (with 22 degrees of freedom and sensory feedback) to begin clinical trials. Rechristened the Modular Prosthetic Limb, it will be grafted onto as many as five real, live persons, the first within the year. Using the targeted muscle reinnervation technique pioneered at the Rehabilitation Institute of Chicago, patients will control these arms directly with their thoughts, and for their sakes and the fate of humanity, hopefully not the other way around. Press release after the break.
