The development of Israeli scientists has several advantages over existing prostheses for damaged nerves. The main one was the continuous work inside the body. Now the authors are ready to launch clinical trials, although they are already confident in the safety of the technology.

Article by Shlomy et al. Restoring Tactile Sensation Using a Triboelectric Nanogenerator is published in the journal ACS Nano – VM.

A team from Tel Aviv University was engaged in the development of a mini-sensor, writes Science Daily. According to the authors, the implant will be a simple and effective solution for those who have lost touch in the limbs after amputation, injury or deep cut. First of all, for safety, because without tactile sensations, a person cannot feel frostbite, burn or mechanical injury.

A tiny sensor is implanted into a nerve of a damaged limb, such as a finger, and connected to a healthy functional nerve. At any touch, the sensor, consisting of two miniature plates, is activated by compression and recreates tactile sensations of the intensity as if a person were healthy.

The electric current comes directly from a healthy nerve, so external charging of the implant is not required.

The installation of the device is also quite simple. The implant material is made of biocompatible material and is safe for humans.

"This is a proven and safe technology that can be implanted in any part of the human body," the authors said.

Preclinical experiments on animal models have shown very promising results. At the first stages of clinical trials, scientists intend to implant an implant in the fingers of people who have lost touch as a result of a domestic injury.
