Electric skin patch could keep wounds free of infection
Zapping the skin with electricity could stop bacteria that live there harmlessly from entering the body and causing blood poisoning
The researchers created square plastic patches that were 1 millimetre wide, each containing gold electrodes that, when wired up, produce electrical pulses that can’t be felt by people. After zapping the skin for 10 seconds every 10 minutes for 18 hours, the team found that S. epidermidis levels were reduced 10-fold on these samples compared with others that had patches put on them, but that didn’t deliver electrical pulses. Widespread antibiotic use is driving an increase in drug resistance and this alternative approach could help slow the crisis, says Munehiro Asally at the University of Warwick, UK.
