Amputee Feels Texture with a Bionic Fingertip

An amputee feels rough or smooth textures in real-time — with his phantom hand — using an artificial fingertip connected to nerves in the arm. The advancement will accelerate the development of touch enabled prosthetics.

I could tell the difference between the
way it was a very rough and smooth yeah

that was amazing when the scientists
stimulate my nose I could feel the

vibration sense of touch in my phantom
index finger

the touches sensation is quite close to
when you feel up with your normal finger

you can feel the coarseness of the
plates and different gaps trips we

showed that it is possible to deliver to
amputees a very sophisticated part of

the sense of touch which is texture
discrimination is it possible to achieve

this thanks to electrode is surgically
implanted into the peripheral nervous

system of the Sept so the fingertip
insiders this miniaturized sensors that

are managed to so many clothes
electromechanical systems that are made

in silicon and they therefore and they
are total those sensors electrical

signals and then he's converted by means
of an artificial neural model into the

sequence of spices bikes are like on off
the events that stimulate the nerve all

the sanctions by means of the annual
interface we also show that it is

possible to deliver the same kind of
inspiration to interact subject using

electors temporal implanted into the
nerves this is extremely important

because now we know that many of the
things we are testing in intact can be

used later if successful universities
this means that we can really actually

rated translation of different
approaches
