New high-tech band-aids could heal wounds faster

The video discusses a high-tech Band-Aid that uses electrical stimulation to accelerate wound healing, as published in ACS Nano. Made from polytetrafluoroethylene, copper foil, and polyethylene, the Band-Aid features electrodes that generate electric pulses from body movements. Tests on rodents showed a significant reduction in healing time from 12 to 3 days compared to normal Band-Aids.

Who explained the functionality of the Band-Aid in the University of Wisconsin news release?

What is the significance of the healing time reduction observed in the study?
