The same wireless technology that can track your cat or locate an item in a warehouse can also monitor your breathing. Researchers at Chalmers University of Technology, Sahlgrenska University Hospital and the University of Gothenburg, Sweden, now present a completely new method for measuring breathing movements in patients with impaired lung function. Using small, plaster-like tags, breathing can be analysed in detail entirely contactlessly – in hospital or at home.

Abstract
Measurement of breathing movement is important for the study of breathing mechanics, the diagnosis, and monitoring of respiratory disorders. Conventional imaging-based methods, such as ultrasound and computed tomography, are either bulky and expensive or highly operator- and position-dependent. In this work, we propose a novel and cost-effective method for measuring local breathing movements, leveraging the well-known radio-frequency identification (RFID) technology. We demonstrate the proof-of-concept by using multiple tags to track localized breathing movements in an experimental study with a medical mannequin. The results indicate that RFID technology can enable accurate breathing measurements under some conditions. However, commercial RFID devices are susceptible to multipath interference, which significantly limits measurement stability and robustness. Reliable measurements in practical settings will require custom-developed system solutions.
