“The enhanced wound healing observed in the PRFE [pulsed RF energy] treatment group is attributed to the localized electromagnetic field generated by the bandage, which facilitates cellular migration, angiogenesis, and tissue regeneration. Our electromagnetic field measurements and animal studies confirmed its efficacy, demonstrating a significantly improved relative wound closure rates (4.2% vs. 21.5% at Day 12) and re-epithelialization (122 ± 4 μm vs. 75 ± 2 μm) after PRFE treatment compared to control groups.”
“Its ultra flexible, battery-free design supports personalized wound care at a low-cost (<US$1). Both EMF simulation and measurement demonstrated that the proposed PRFE bandage achieves the field strength of clinical-grade PRFE equipment.”
Note that the PRFE-bandage uses only passive components.
