A highly sensitive stretchable strain sensor based on multi-functionalized fabric for respiration monitoring and identification

Wearable strain sensors have generated considerable recent research interest due to their huge potential in the real-time detection of human body deformation. State-of-the-art are normally fabricated through conductive networks with a single sensing element, which always faces challenge either limited stretchability or inferior quality sensitivity. In this work, we report highly sensitive sensor based on multi-functionalized fabric carbonization and polymer-assisted copper deposition. The shows high sensitivity (Gauge factor ? 3557.6 range from 0 48%), outstanding up 300%, is capable detecting different types deformation body. By integrating high-performance deep learning network, demonstrate high-accuracy respiration monitoring emergency alarm system, showing enormous application personal public healthcare.
