• To develop the ultrasonic non-invasive system for glucose monitoring in human body, the basic insonation effects were investigated on the mechanical force of bubbly sound field. A way was shown by means of Mason's equivalent circuit how to detect the Stress in water by a PZT sensor with a rubber baking. It was found that a Bubbly activated sound filed was generated beyond the threshold stress 0.2 M Pascal and its stress was magnified with the nonlinear waveform, apart from a sinusoidal one in weak case. Also, there appeared the 1/m sub-harmonics and their overtones. On the other hand, the same measurement was done on the sliced big's thigh meat. The corresponding waveform vs. time was complex but displayed the sub-harmonics. The resulting instantaneous maximum stress happened to be over 0.6 M Pascal.
