Prof. Chen Tao’s team at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of Chinese Academy of Sciences (CAS) has proposed strain-perception-strengthening (SPS) enabled biomimetic soft skin, which realizes the dynamic transformation from tactile to pain perception. The study was published in Advanced Functional Materials.

Creatures with biological soft tissues (e.g., skin) can achieve self-protection through passive strain mechanical stiffening and active perception of external stimuli. Prior to strain mechanical stiffening, the active protection can sense dangers in advance, and thus greatly decrease the risk of injury. However, it …
