The tactile sensor indicated that increases in stiffness (decreases in the slope of the tangent of the hysteresis curve) and decreases in elasticity (increase in the residual deformation) of the masseter muscle on the mastication side were proportional to the number of masticatory cycles, which were measured at 0, 50, and 100 cycles.

using a tactile sensor. [English abstract, graphs and tables] Shika Igaku (Journal
of the Osaka Odontology Society), 2000 Mar; 63 (1): 23-32. |

| DfS (mean±SEM, N = 10) for stiffness vary with the six measurement sites on a slice of prostate tissue. Low SEM indicates that the results are reproducible. TissueMix according to histological investigation and eqn. 6 are represented by dots. Softer tissue results in a greater negative frequency shift. FC = 87.6 ± 1.0mN (mean±SD, N = 90).

| Mixture A contains water, alcohol, and moisturizing lotion. Mixture B contains only water and alcohol. Each liquid was applied to the inner forearm of each subject. Figures 5 and 6 show a direct relationship between skin hardness, as measured in terms of change of frequency, and amount of skin moisture.
