Bacterial biofilms represent a major wound complication. Resistance of biofilm towards drug interventions calls for alternative strategies. Bacteria rely on electrostatic interactions to adhere to surfaces, an important aspect of biofilm formation. The concept that weak electric fields may have anti-biofilm property was first reported in 1992. Special bandages using weak electric fields disrupt bacterial bio-film infection, combat antibiotic resistance and enable healing in infected burn wounds. The dressing becomes electrically active upon contact with bodily fluids.
