“The stimulation felt almost like what I would feel with my hand,” says Sørensen. “I felt the texture sensations at the tip of the index finger of my phantom hand.”
"I could feel things that I hadn't been able to feel in over nine years."The experimental system was developed by EPFL (Ecole polytechnique fédérale de Lausanne) and SSSA (Scuola Superiore Sant’Anna).

“This achievement will allow the “symbiosis” between the user and interface to become more adaptive (to changing tasks and situations), more robust (beyond interfering stimuli), more effective (learn from the past to anticipate or predict the future), and more natural (rapidly becoming part of the body scheme).
Therefore, the restoration of sensory perception is the crucial step to achieve in the development of next generation of artificial limbs and hand prostheses…”
A new material could revolutionize robotics and prosthetics.
This graphene elastomer is a flexible, ultra-light material which can detect pressures and vibrations across a broad bandwidth of frequencies. It far exceeds the response range of our skin, and it also has a very fast response time…
Although we often take it for granted, the pressure sensors in our skin allow us to do things like hold a cup without dropping it, crushing it, or spilling the contents.
The sensitivity and response time of G-elastomer could allow a prosthetic hand or a robot to be even more dexterous than a human, while the flexibility could allow us to create next generation flexible electronic devices.
Synthetic skin and nerves which grow and communicate
It is a flexible, skin-like material able to detect pressure and also transmit a signal to a component of the nervous system,” says Stanford's Andre Berndt.
"Any sufficiently advanced technology is indistinguishable from magic."
