When I expect Johnny Matheny if I could excite his hand , I was confessedly a small aflutter . The soft - spoken Floridian lost his lower leftover arm to genus Cancer eight years back . His new arm — an advanced , judgement - controlled prosthetic develop by DARPA — can squash a human human skull like a child squeezing a clementine .
Of course , Matheny is a professional , and he pay me a very manipulate , firm handshake . While you ’d never mistake the automatic , carbon fibre arm for its flesh - and - blood counterpart , in damage of dexterity , the two are pretty darn tight . If we ’re talkingraw strength , the synthetic subdivision is far ranking .
“ This thing has as skillful a reach of motion as a natural manus , ” Matheny say in his charming southern twang , explain how he could greet you with his right hand while opening a motorcar doorway behind him with his leftfield . “ The only thing it ca n’t do is the Vulcan volt , ” he bestow , referring to the universal nerd pride motion popularized by Star Trek .

Matheny is a bonafide cyborg — one of the most in advance in the human beings . The “ Modular Prosthetic Limb ” he was assume when we met at a DARPA technology exposition this hebdomad is a highly enunciate , computer - drive equipment plan for full neural desegregation . That means it ’s up to of receiving sign from the human mind and , paired with the right surgical implants , transmit signals to the head .
This is a far rallying cry from the rigid , shoulder strap - on prosthetics X of thousands of men and women wear thin today . pair an stilted limb with a organic brainis a dreaming direct out of science fabrication , something DARPA proudly recognize . ( In fact , DARPA and the company DEKA are working on another mind - controlled prosthetic subdivision that’snicknamed “ Luke”after Luke Skywalker . )

“ The end is really to capture the brain ’s purport and turn it into motion very naturally , ” sound out Justin Sanchez , music director of the Biological Technologies Office at DARPA . Sanchez , who was at the Pentagon aid DARPA show off its badass prosthetics this week , explained that theMyo armbandMatheny was wearing around his upper branch picks up electric signal from his muscles . Those signals are impart via Bluetooth to a computing machine inside the prosthetic arm , which drive motors inside the machine .
Matheny has been tryout - driving prosthetics for DARPA since 2011 , and his ability to interface with machines has gotten some major upgrade along the style . year ago , he received targeted muscle reinnervation ( TMR ) , a operative subroutine that reassigns nerves in a residual limb to make better function of a prosthetic replacement . In the give of 2015 , Matheny became the first American with TMR to undergoosseointegration , another surgical procedure that allows him to connect prosthetic machine directly to the off-white of his upper arm . When he first attached the Modular Prosthetic Limb via osseointegration last dusk , the transformation was immediate . “ Before , I had circumscribed range ; I could n’t strain over my oral sex and behind my back , ” Mathenysaid at the time . “ Now microphone boom , that restriction is gone . ”
And all of this is just the beginning . Pointing to his machinelike fingertip , Matheny explained that they already contain tactile sensor capable of detecting grain , pressure , and temperature . But in order for Matheny to feel what his prosthetic arm feels , those signal have to reach his mastermind . In the not - too - distant future , another surgical procedure may enable this .
It entails implanting two small-scale twist along nerves parcel in Matheny ’s breast and back . These nerves , which are wired directly to the brain ’s somatosensory cortex ( a realm where star are processed ) , would be stimulated based on information beamed wirelessly from the prosthetic hand . In heart , DARPA wants to create a closed in circuit that melds synthetical and biological wire .
DARPA is working hard to fine - melodic line those receptive implant , in addition to implants that transmit information the other way to put back wearable equipment like the Myo armband . “ The Myo band has to be calibrated every day , and it only offers so much controller , ” say Doug Weber , curriculum manager at DARPA ’s Biological Technologies Office . “ Once you have pocket-size sensors that can be implanted into many muscles , you could get many more control channels . alternatively of have to do things sequentially : strike my elbow , radiocarpal joint , then finger , I can do all of those thing together . ”
Early versions of these implantable devices are already being tested in human . So far , the result are promising : the technology not only restores a mother wit of soupcon , it can dramatically slenderize the phantom limb pain experienced by many amputees .
The life - changing impact of DARPA ’s mind - controlled limb was clear after spending just a few minutes with Matheny — as was the fact that we ’ve barely cancel the surface of this technology ’s potential . Devices like the Modular Prosthetic Limb may be expensive and experimental for now , but it ’s not hard to guess them becoming widespread in the futurity . In fact , I ca n’t aid but wonder whether our cyborg descendants — sporting modular arms that set tool of all shapes and sizing — will bet back on the early 21st century and wonder how man ever got on with two slight , constitutive nitty-gritty sticks , equipped with only ten fingers each .
