Abstract
Breathing is vital to life. Therefore, the real-time monitoring of a patient′s breathing pattern is crucial to respiratory rehabilitation therapies, such as magnetic resonance exams for respiratory-triggered imaging, chronic pulmonary disease treatment, and synchronized functional electrical stimulation. While numerous respiratory devices have been developed, they are often in direct contact with a patient, which can yield limited data. In this study, we developed a novel, non-invasive, and contactless magnetic sensing platform that can precisely monitor a patient′s breathing, movement, or sleep patterns, thus providing efficient monitoring at a clinic or home. A magneto-LC resonance (MLCR) sensor converts the magnetic oscillations generated by a patient′s breathing into an impedance spectrum, which allows for a deep analysis of one′s breath variation to identify respiratory-related diseases like COVID-19. Owing to its ultrahigh sensitivity, the MLCR sensor yields a distinct breathing pattern for each patient tested. It also provides an accurate measure of the strength of a patient′s breath at multiple stages as well as anomalous variations in respiratory rate and amplitude. The sensor can thus be applied to detect symptoms of COVID-19 in a patient, due to shortness of breath or difficulty breathing, as well as track the disease′s progress in real time.

Bacteria and viruses threaten our lives on a daily basis and are responsible for severe plagues
In December 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), known as COVID-19, began to spread across the globe and has since caused the suffering and loss of life of millions of people [3,4]. This deadly virus has a structure similar to severe acute respiratory syndrome (SARS) and is highly contagious, as it can spread from one person to another through air [5]

Summary
Bacteria and viruses threaten our lives on a daily basis and are responsible for severe plagues. It is essential to develop high-performance healthcare monitoring devices that can detect a pathogen and provide accurate health condition data and progress [1,2]. In December 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), known as COVID-19, began to spread across the globe and has since caused the suffering and loss of life of millions of people [3,4]. This deadly virus has a structure similar to severe acute respiratory syndrome (SARS) and is highly contagious, as it can spread from one person to another through air [5]. Detecting and tracking COVID-19 represents an incredibly challenging task, recent efforts have been devoted to achieving this ultimate goal [6–14]
