Characterization and analysis of dynamic implant communication channels based on inhomogeneous model
Abstract:
Implant communication plays an important role in achieving information exchange among implantable devices in personal health care. In this paper, the characteristics of dynamic implant communication channels (ICCs) are studied by using a set of 30 inhomogeneous human body models (frames) which corresponded to one period of a walking motion. The gain variations of three different ICCs (from belly to head, right wrist, and right ankle) are investigated at 21MHz, 403.5MHz, and 2.45GHz, respectively. The results show that the ICC gain may be affected by body posture, body shadowing effect, multipath fading, and earth ground. In addition, compared with the ICC gain at 403.5MHz and 2.45GHz, the ICC gain at 21MHz is motion-insensitive in implant communication.

Parameters Affecting Nonlinear Elimination: Zero-Order Input, First-Order Absorption and Two-Compartment Model
When a drug is administered through a constant intravenous infusion and eliminated via nonlinear pharmacokinetics, it follows zero-order input. For example, oral drugs undergo first-order absorption upon administration and are eliminated through nonlinear pharmacokinetics.
In the case of subcutaneously administered drugs,...
