Wide‐Bandwidth Nanocomposite‐Sensor Integrated Smart Mask for Tracking Multiphase Respiratory Activities (Adv. Sci. 31/2022)

Smart Masks In article number 2203565 by Ho‐yin Chan, Xinge Yu, Jianping Wang, Wen Jung Li, and co‐workers, a “smart mask” is developed by using an ultrathin nanocomposite‐based soundwave sensor with high sensitivity and wide‐bandwidth dynamic range, i.e., integrated with machine/deep learning algorithms, the smart mask can identify breath, two‐/tri‐phase coughs, and spoken words directly. The smart mask could be a new wearable Internet of Things device for personal health monitoring and respiratory disease identification tool in the future. [Image: see text]
