A resonance frequency technique to determine the energy absorbed in stratum corneum ,800 Hz. The softness of stratum corneum was measured in terms of loss tangent (tan .), a dimensionless number. An acoustic spectrometer was used to determine the resonance frequency, and the results obtained were recorded on an . recorder. The vertical displacement of the arm of the transducer was cconflate 发表于 2025-4-1 07:49:27
The mechanism of stratum corneum plasticization with waterviscoelastic properties of stratum corneum were also measured to investigate its plasticization mechanism..The pliability of human stratum corneum increased rapidly above 60% RH. The water sorbed in human stratum corneum was found to be ‘bound water’ in the range 0-60% RH but to include ‘free water’Jingoism 发表于 2025-4-1 12:09:57
