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|
|Chemical scar||100-130, 175-185||3.04||5.78|
