Electronic Skin The new electronic skin can give people with prosthetics a partial sense of touch - pressure, temperature, and even surface texture. The entire system is 10 times more accurate than commercial sensors in modern robotic gloves. It consists of thin, multi-layered modules that contain pressure and temperature sensors, which work like human skin: they detect the slightest changes and transmit data in real time. The main achievement is the ability to create skin of an individual shape that precisely replicates the curves of a specific prosthesis. This is done using the "scan-model-print" method: the prosthesis is first scanned, then a sensor map is applied to its geometry, and everything is printed in 3D. The sensors do not require glue - the modules simply snap together like constructor parts. The sensor density is high: the system covers flat and curved surfaces without "blind spots". At the same time, production remains cheap - laser cutting and regular 3D printing are used. This makes electronic skin available for mass use, not just for expensive experimental prosthetics. In the future, developers want to add feedback so that a person can not only "collect data" but also really feel the touch. Researchers are already working on an actuator that will convert sensor signals into nerve stimulation near the amputation site, as described in Cell Reports Physical Science. 🔗 Read original →
