MinTouch technology does this from the fingers of the artificial hand. “thermal information” amputee person transferring it perfectly to the remaining limb doing. SwitzerlandResearchers at the École Polytechnique Fédérale de Lausanne in Lausanne, Turkey, found that this sensory input affects amputees’ environments. explore and interact more safely He believes that it will increase their capacity.
“Adding temperature information, It makes touch more human. “We think having the ability to feel temperature will enhance the experience of prosthetic wearers embracing their bodies,” he said.
Recognizing sensations such as pressure, pain, vibration, and temperature is critical to interacting safely and efficiently with our environment. As a result, it is critical to create technologies that can restore sensation to people who wear prosthetics.
This non-invasive technology allows amputees to It can be easily placed on prosthetic limbs. According to the press release, during activities that require feedback between sensory and motor neurons “active thermosensation” It works by providing .
The temperatures of the bottles could be distinguished with 100% accuracy
In the tests, researchers integrated this new bionic device into the prosthetic limb of a man who had undergone transradial amputation 37 years ago. device, the participant The phantom on his remaining limb was strategically attached to a point on his index finger that triggered thermal sensations. The researchers then evaluated the man’s ability to distinguish between objects and materials of varying temperatures. Remarkably, with the help of the MiniTouch, the participant demonstrated the ability to effectively distinguish different temperatures.
Can distinguish human touch
The participant also demonstrated the ability to classify metal cubes based on their temperature and describe the sensation of human touch. Even while blindfolded with the device was able to distinguish between human limbs and artificial limbs ve %80 such an impressive accuracy rate reached.
The statement emphasizes that the device still has some limitations in terms of human touch compared to the solid arm. Researchers say this limitation is due to the prosthesis Inability to convey information regarding skin softness and texture He thinks it may be linked to limitations in other non-thermal sensory data, such as
Talking about his future goals in the press release, Shokur said, “Our current goal is touch, movement perception (profrioception) and temperature combining one’s senses a multi-mode system to develop. With this kind of system, people ‘it’s soft and warm’ or ‘it’s hard and cold’ “They will be able to say,” he said.
