In-body Bionanosensor Communication and Localization for Anomaly Detection

Nanotechnology enables the development of a new generation of devices which are able to sense, process and communicate while being in the scale of tens to hundreds of cubic nanometers. Such small, imperceptible devices enhance not only current applications but enable entirely new paradigms especially for in-body environments. This paper introduces a localization concept for bionanosensors floating in the human bloodstream to detect anomalies in the body. To realize autonomous localization and resource-efficient communication, we propose to exploit inertial positioning and sub-terahertz backscattering. Our concept is a first step towards early disease detection as it aims at localizing body regions which show anomalies. Simulations are conducted to enable a systematical evaluation on the feasibility of the approach.
