Acoustic Power Distribution Analysis in Different Human Tissues for Bioimplant Application

For the accurate monitoring of tissues for therapeutic, diagnostic, and power transfer applications, reduction of bio-effects, and improvement in the acoustic image quality, it is important to analyse the propagation of acoustic waves in different varieties of human tissues. Therefore, in this work, an acoustic transmitter operating on the frequency of 4.6 kHz at 5 volts excitation voltage and a tissue phantom are simulated and analysed for two different tissues, viz. bone and muscle. Consequently, the power intensity of 1.50 mW/m
²
and 10.44 mW/m
²
is obtained in bone and muscle, respectively. The experiment resulted in the average output voltage of 0.757 V in the palm, 0.189 V in wrist, and 0.013 V near the elbow region in male subject, while 1.26 V in palm, 0.533 V in wrist, and 0.145 V near the elbow region in the female subject. The study depicts that the application of acoustic waves is more efficient in the muscle medium and less efficient in the bone medium.
