Created by nature, the human skin shows powerful sensing capabilities that have been pursued by scientists for a very long time. However, it is challenging for today's technologies to replicate the spatial arrangement of the complex 3D microstructure of human skin.

A research team led by Professor Yihui Zhang from Tsinghua University has developed a three-dimensionally architected that mimics human mechanosensation for fully-decoupled sensing of normal , shear force and strain.

Their findings were published in Science.

Taught by nature

Inspired by human skin, they created a three-dimensionally architected electronic skin with force and strain sensing components arranged in a 3D layout that mimics that of Merkel cells and Ruffini endings in human skin.

This 3DAE-Skin shows excellent decoupled sensing performances of normal force, shear force, and strain. It is the first-of-its-kind with force and strain sensing components arranged in a 3D layout that mimics that of slowly adapting mechanoreceptors in .

Enchanted by artificial intelligence

With the assistance of , they developed a tactile system for simultaneous modulus/curvature measurements of an object through touch. Demonstrations include rapid modulus measurements of fruits, bread, and cake with various shapes and degrees of freshness.

The resulting technology provides rapid measurement capabilities of the friction coefficient and the modulus of an object with diverse shapes, with potential applications in freshness assessment, biomedical diagnosis, , prosthetic systems, among others.

Zhang's study was done with colleagues from Tsinghua University's Applied Mechanics Laboratory, Department of Engineering Mechanics and Laboratory of Flexible Electronics Technology.
