Scientists from Tsinghua University in China have created the world's first “electronic skin” with a bionic three-dimensional architecture. It replicates the functions of collagen and elastin, maximally mimicking the softness and complexity of the largest human organ. A fragment the size of the tip of an index finger is equipped with 240 metal sensors, each measuring between 200 and 300 microns. The sensors collect signals that are carefully processed using deep learning algorithms. This allows the “artificial skin” to accurately distinguish the texture and contours of objects when in contact with them. The development is capable of simulating several mechanical signals recorded in human skin - pressure, friction and deformation. The authors of the development believe that the “electronic skin” can be used for early diagnosis and treatment of diseases and as a patch to monitor health indicators in real time, including blood oxygen saturation and heart rate.
