Electrostatic Face Mask Self-Charges with Breathing

Researchers at City University of Hong Kong have developed an electrostatically charged face mask that can replenish its charge through the wearer’s breathing action. The electrostatic charge helps the mask to adsorb tiny particles, such as SARS-CoV-2 viruses. However, such masks typically lose their charge and ability to bind particles over time, particularly in humid … Continue reading Electrostatic Face Mask Self-Charges with Breathing
