A team of researchers at the Centre for Nano and Soft Matter Sciences (CeNS), Bangalore, an autonomous institute of the Department of Science and Technology (DST), have come up with a recipe for making face masks, termed as TriboE Mask.
It can hold electric charges to restrict the entry of infections but interestingly, without any external power.
It relies on electrostatics.
The tribo electric effect is also known as tribo electric charging.
It is a type of contact electrification on which certain materials become electrically charged after they are separated from a different material with which they were in contact.
