Mobility Matters at Nanoscale: Rendering the Received Terahertz Signal Power in Human Blood Vessels

We evaluate the received power level of transmitted signals between flow-guided nanosensors in human blood vessels. The power budget calculation accounts for the radiation pattern of a dipole-like nanoantenna and the variability of the nanosensor position. We model the nanosensor mobility component not only as displacement but also as the rotation produced by the blood flow. Our results show that the varying distance among nanosensors influences the average power component, while the power level variance results from the antenna’s rotation. This simulation model contributes to portraying communication capabilities at the nanoscale, and considering realistic evaluations with the blood flow dynamics.
