Pain threshold induced by local exposure to millimeter waves on human skin

Year: 2026

Type: article

Abstract: This study investigated the perception thresholds of four types of sensations-warmth, heat, tingling, and pain-when the fingertip was exposed to 28 GHz millimeter waves. The results showed that the perception thresholds followed the order of warmth, heat, tingling, and pain, with the threshold skin temperature for pain at 41.9°C. Notably, females exhibited significantly higher sensitivity to pain than males. These findings provide further evidence supporting the need for protection from millimeter-wave exposure.
