【 摘 要 】

tsTwo functionally different anisotropic layers are rationally assembled for highly selective and stretchable multidirectional strain sensors.Concurrently excellent selectivity, sensitivity, stretchability, and linearity up to 100% strain is demonstrated for the first time in a multidirectional strain sensor.A novel stepwise crack propagation mechanism is proposed to enable high stretchability and linearity.
