Security vulnerabilities demonstrated in implantable medical devices have opened the door for research into physically secure and low power communication methodologies. In this study, we perform a comparative analysis of commonly used ISM frequency bands and human body communication (HBC) for data transfer from in-body to out-of-body (IBOB). We develop a figure of merit (FoM) that comprises of the critical parameters to quantitatively compare the communication methodologies. We perform finite-element method (FEM)-based simulations and experiments to validate the FoM developed.

IBOB通道物理安全和路径损耗随频率的定量分析

植入式医疗设备中显示的安全漏洞为研究物理安全和低功耗通信方法打开了大门。在这项研究中，我们对常用的 ISM 频段和人体通信 (HBC) 进行了比较分析，用于从体内到体外 (IBOB) 的数据传输。我们开发了一个品质因数 (FoM)，其中包含用于定量比较通信方法的关键参数。我们执行基于有限元方法 (FEM) 的模拟和实验来验证开发的 FoM。
