Researchers have engineered an electrostatic face mask that can 'self-charge' through the user's breathing and continuously replenish its electrostatic charge as the user wears and breathes through ...

Fig. 1. Self-charging air-filtering mask with prolonged electrostatic adsorption. (a) Schematic diagram of the proposed self-charging air-filtering mask. (b) Enhanced particle capture capacity with ...

Electrostatics, the study of stationary or slowly varying electric charges, underpins much of modern physics and engineering. At its core, this field examines how charges interact, the resulting ...

Electrostatic adsorption is an important complement to mechanical filtration for high-efficiency air filtering in the use of face masks. However, the electrostatic charge of the filters decays over ...
