Tribo E Mask

IN NEWS:

• A team of researchers at the Centre for Nano and Soft Matter Sciences (CeNS), Bangalore have come up with a recipe for making face masks, termed as Tribo E Mask.

Tribo E Mask:

• Tribo E Mask can hold electric charges to restrict the entry of, without any external power.
• The innovation relies on electrostatics. When two non-conducting layers are rubbed against each other, the layers develop positive and negative charges instantly and continue to hold the charges for some time. They have used this electric field to deactivate or possibly even kill the germs.
• The mask is three-layered –a layer of nylon cloth sandwiched between polypropylene layers. When layers are rubbed against each other, the outer layers develop negative charges, while nylon will hold the positive charges.
