Scientists in Switzerland created a new bionic hand technology called MiniTouch.
MiniTouch helps amputees feel temperature changes in their "phantom limb" (the feeling of having a limb they no longer possess).
The technology works by transferring heat sensations from the prosthetic hand to the user's remaining limb.
In tests, a participant with an above-the-wrist amputation successfully identified different water temperatures and even human touch using MiniTouch.
This non-invasive technology could improve amputees' ability to interact with their surroundings safely and naturally.
While promising, the researchers aim to develop a more advanced system that also transmits other sensations like texture and pressure.
The study was carried out at École Polytechnique Fédérale de Lausanne and published in the journal Med.
