Self‐Assembled Wavy Optical Microfiber for Stretchable Wearable Sensor (Advanced Optical Materials 11/2021)

Fei Xu, Hengtian Zhu, and co-workers (article number 2002206) demonstrate a self-assembled wavy optical microfiber for stretchable wearable sensors. The approach inspired by the bottom-up strategy for forming wavy geometries in microfibers is controllable and suitable for mass production. With great sensitivity and repetition, human pulse wave and blood pressure were successfully monitored, showing a potential for real-time health care applications.
