A non-invasive lung monitoring sensor with integrated body-area network

This paper discusses the design and testing of a new robust system for in-situ continuous monitoring of the lung´s condition. The system is composed of a body worn medical sensor with an accompanying wireless body area network (BAN) for remote health monitoring. The lung sensor consists of 17 electrodes, and operates at 40MHz. It aims to approximate the dielectric constant of the underlying lung tissue independent of variations in the outer layers (skin, fat, muscle and bone). Concurrently, the wireless BAN is used to transmit the measured dielectric constant to a mobile device via Bluetooth for continuous remote healthcare monitoring. In this paper, we present the design and experimental validation of the proposed lung sensor integrated with wireless BAN data link.
