Abstract

In the recent decade, the e-health care industry has seen a rapid growth in state-of-the-art advancement in many related fields. The ability of biosensors to stimulate and continuously monitor vital organs has proven to be helpful for various medical conditions ranging from seizures to cancer. To build devices with such capabilities, challenges in various domains, such as biocompatible materials, low-power wireless communication, processing, and sensing techniques, must be solved. Most of the proposed device models have used a single energy source for powering and communication, without the implementation of error-correction/detection techniques, thus limiting the communication range to millimeters. This work proposes a bio-mote, a model of a communication device that can circulate inside the human body and communicate with a wearable or handheld device such as a cell phone. The proposed model has integrated low-power modulation, powering, and error-correction techniques in order to communicate with an external device that is placed at a distance in the centimeter range. Assuming the human body to be an additive white Gaussian noise (AWGN) channel and with an implant coil radius of 30 ?m, performance of the proposed model has been analyzed using MATLAB. A maximum communication range of 5 cm with a bit error rate (BER) of 0.0001 has been achieved.
