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
