Table 1: Resonant frequencies and moduli values of normal skin, thermal and chemical scar tissue. Note there are two peaks in Figure 4 measured for the chemical burn yielding two moduli. The first modulus (Modulus 1) represents the tissue that is still unhealed and the second modulus (Modulus #2) represents the modulus for the healed tissue.
Tissue | Resonant frequencies (Hz) | Modulus 1 (MPa) | Modulus #2 (MPa) |
Skin | 90-100 | None | 2.0 to 3.0 |
Thermal scar | 220-230 | None | 7.0 |
Chemical scar | 100-130, 175-185 | 3.04 | 5.78 |
