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 ...

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 ...

Sam England and Daniel Robert, biologists at the University of Bristol, report that at least three types of caterpillars are capable of sensing and responding to an electrostatic field generated by a ...

Unlike traditional lab-based methods, the GranuCharge AL provides instant access to the charge per mass measurement thanks to its integrated load cell combined with a Faraday cup connected to a highly ...
