Revolutionary Bionic Technology Allows Amputees to Feel Human Touch and Temperature Sensations.

Researchers at the École polytechnique fédérale de Lausanne (EPFL) have developed a bionic technology that allows amputees to feel hot or cold sensations in their phantom hand and fingers, as well as directly on the arm, through thermal electrodes placed on the skin of their residual arm. The technology, which has been tested for more than two years, does not need to be implanted and can be worn on the skin and combined with a regular prosthetic. The researchers hope that the technology could lead to a more natural feeling of loved ones when amputees are wearing their prosthetic.
