SINEW Mask

The Smart, Individualized, Noncontact, Extended-Wear (SINEW) Mask


How It Works: Surface Ionization Technology

The SINEW Mask uses electrohydrodynamic (EHD) technology to provide a novel air-pressurizing device that surpasses other comparably effective PPE in size, weight, and comfortability while maintaining a high filtration efficiency.

The filtering takes place along the entire mask perimeter, a few millimeters away from the face, see. Particles and droplets present in the air are removed with electrostatic forces (electrostatic filtration – ESF). The electrostatic collector rapidly charges the particles in the charging region and collects the charged particles on the collection electrode. High ion concentration and the electric field between the emitter and collection electrode result in high particle collection efficiencies. The unique advantage of this design is that it filters out particles without touching the skin of the wearer’s face.


What we're working on: Dielectric Barrier Discharge

Dielectric Barrier Discharge (DBD) is a type of electrical discharge that occurs in a gas between two electrodes separated by a dielectric. When the high-voltage AC power supply is turned on, a strong electric field is created across the dielectric, inducing DBD. This material between the high-voltage electrodes prevents arcing between them, instead confining many ‘micro-discharges’ into a small area. This creates a DBD plasma of ionized gas, where charged particulates influenced by the powerful electric field move toward the oppositely-charged electrodes and are collected on the dielectric.
