Despite advances in flexible humidity sensors, real-time monitoring of breath for extended
periods of time remains a problem. Traditional breath sensors have drawbacks such as …

Monitoring respiratory variables can provide valuable information for clinical applications
and sport activities. Paper-based wearable respiration monitoring systems have great …

Flexible respiratory monitoring devices have become available for outside-hospital
application scenarios attributable to their improved system wearability. However, the …

The frequency of breathing and peak flow rate of exhaled air are necessary parameters to
detect chronic obstructive pulmonary diseases (COPDs) such as asthma, bronchitis, or …

A frugal humidity sensor that can detect changes in the humidity of exhaled breath of
individuals has been fabricated. The sensor comprises a humidity-sensitive conducting …

This present work provides an easily disposable paper-based interdigitated sensor
embedded inside the mask for the detection of respiration rate continuously without direct …

Flexible and stretchable humidity sensors for wearable purposes have become increasingly
important in health care and physiological signal monitoring. However, to the authors' …

Accurate measurement and monitoring of respiration is vital in patients affected by severe
acute respiratory syndrome coronavirus–2 (SARS-CoV-2). Patients with severe chronic …

We present a sensor made from paper using a Do-It-Yourself (DIY) integration strategy that
can be attached to the human chest like a stethoscope for real-time asthma symptom …

Respiratory monitoring is crucial for evaluating health status and identifying potential
respiratory diseases such as respiratory failure, bronchitis, and pneumonia. Humidity …
