A fully integrated wireless facemask with mCP/ZIF-8-NH2@fCOF nanocomposite enables ultrafast, humidity-resistant exhaled CO2 monitoring for breathing pattern classification and disease diagnosis.
The smart facemask uses a nanocomposite colorimetric sensing material with a 60 ms response time and hydrophobic shell to resist humidity. Coupled with a convolutional neural network, it identifies breathing patterns with 94% accuracy and diagnoses chronic obstructive pulmonary disease with 93% accuracy. It also proves effective for exercise monitoring and sleep apnea detection.
