Towards practical implementation of molecular communication: A cost-effective experimental platform based on the human circulatory system

Recently, there have been numerous studies exploring the field of molecular communication (MC) systems. However, due to the high cost and limited availability of advanced micro/nano-scale equipment, most of these works remain purely theoretical, with only a few being examined through experimental platforms. Additionally, the absence of a suitable model for flow-assisted MC-based systems poses another significant challenge. This research focuses on the potential applications of MC technology within the human body. To address the limitations mentioned above, a closed-loop experimental platform based on the human circulatory system is proposed. This platform offers a cost-effective and accessible solution for studying MC systems. The implementation process involves a brief discussion about the circulatory system model. By varying flow rates and the quantity of released information particles, channel impulse responses are obtained. Based on the observed experimental data, the authors have successfully developed a new theoretical model that accurately fits the experimental data. The model demonstrates a strong level of agreement with the observed results. This model demonstrates its suitability for flow-assisted MC-based systems. This article explores the potential applications of molecular communication (MC) technology within the human body. To overcome the limitations of theoretical studies and the absence of a suitable model for flow-assisted MC-based systems, the authors propose a closed-loop experimental platform based on the human circulatory system. By varying flow rates and the quantity of released information particles, channel impulse responses are obtained, leading to the proposal of a new model that demonstrates its suitability for flow-assisted MC-based systems.image
