Scientists at have developed a bionic fingertip that can help amputees differentiate between rough and smooth surfaces.
The scientists are from the Swiss Federal Institute of Technology in Lausanne and Sant’Anna School of Advanced Studies in Pisa, Italy.
The research team asked amputee Dennis Aabo Sørensen to test it out.
“Yeah. That was amazing.”
These are words from Sørensen, the first person to feel texture using a bionic fingertip surgically joined to nerves in his upper arm.
“The stimulation felt almost like what I would feel with my hand,” says amputee Dennis Aabo Sørensen about the artificial fingertip connected to his stump. He continues, “I still feel my missing hand, it is always clenched in a fist. I felt the texture sensations at the tip of the index finger of my phantom hand.”
The research was published in the journal eLife.
