Abstract

Abstract: Bio-electromagnetic compatibility for artificial anal sphincter is investigated in this paper. Through segmentation of the image, the tissues are divided and identified. Electromagnetic model of human body is established with 40 kinds of tissues. The radiation dose of the transcutaneous energy transfer system on biological tissues is calculated using the finite difference time domain (FDTD) method. The specific absorption rate distribution of different tissues is obtained in the electromagnetic field. The safety analysis is carried out according to the international standard for electromagnetic safety of human body. The simulation results show that the transcutaneous energy transfer system has good biocompatibility to human tissues when transmitting power is 1500mW and resonant frequency is 358kHz in the experimental environment.

Key words: artificial anal sphincter, transcutaneous energy transfer, finite difference time domain (FDTD) method, bio-electromagnetic compatibility
