Figure 2.

Qualitative assessment of skin damage via visual confirmation. Real-color pictures of synthetic skin samples at body temperature (assessed up to 120 s at initial temperature of 37 °C and t = 0 s) before and after their exposure to 20 s intervals of microwave heating at 2, 4, 5, 10, 15, and 20 W. Green frames denote no tissue damage at 2 and 4 W. Red frames denote tissue damage after 120 s of microwave heating at 5, 10, 15, and 20 W.
