Abstract: This paper represents the effect of amplitude modulated ultrasonic standing waves in determining the glucose concentration in dextrose mixed intralipid based tissue phantom. The intralipid exhibits biological tissue related light absorption, reflection, scattering properties. The intralipid act as a suitable substitute medium for tissue related lab based experimentations. The ultrasonic waves were produced here using two sinusoidal waves. Phase of the ultrasonic waves were controllable in nature. The piezoelectric crystal based ultrasonic transmitter and receiver of 40 kHz were used here. The ultrasound produced here causes series of vibrating pattern on the area of its applications. Molecules usually vibrate specifically based on their structural orientations and physical properties. The vibration patterns of glucose molecule were observed here using infrared LED of 940nm. The experimental design and resultant output in Fast Fourier Transform Domain for glucose prediction in dextrose mixed intralipid phantoms had been described and discussed in this paper. This technology can be utilized to design and improve noninvasive blood glucose monitoring devices
