An in-body wireless communication system for targeted drug delivery: Design and simulation

Statistics show that the figure of new cancer cases and deaths reported each year are increasing considerably. The current situation demands an efficient targeted drug delivery system that enables localized drug administration which can be externally controlled. This paper proposes a remotely triggered targeted drug delivery system that is capable of providing drugs to multiple patients in a periodic basis and works according to the instructions transmitted from the external transmitter module. We present the characteristics and challenges in the propagation of Radio Frequency (RF) signals through different body tissues from the perspective of targeted drug delivery system so that the analysis can lead to the selection of optimum frequency needed for in-body communication. This paper focuses on the design of an implantable drug delivery system, based on the optimum frequency obtained from the simulation results.
