Crocodile‐Skin‐Inspired Omnidirectionally Stretchable Pressure Sensor (Small 52/2022)

Omnidirectionally Stretchable Pressure Sensors In article number 2205643, Seung Goo Lee, Kilwon Cho, and co-workers report an omnidirectionally stretchable pressure sensor that is geometrically and functionally inspired by the unique sensory organ in crocodile skin that can detect tiny disruptions on the surface of water. The stretchable pressure sensor made of polydimethylsiloxane/silver nanowires composites with microdomes and wrinkled surfaces can detect pressure changes with high sensitivity even under not only uniaxial tensile strain but also biaxial one.
