Self-cross-linked arrays enabled flexible mechanical sensors for monitoring the body tremor

Abstract Thin-film electronics played an important role in flexible healthcare sensor applications. The common status of their constituent blocks are solid film and network structures. However, the solid film could only sustain bend in a narrow range due to cracks, and the network structure decrease...
