Making a Shirt That Measures Lung Volume

This project presents a noninvasive shirt equipped with IoT capabilities for measuring lung volume data. The researchers developed a system using capacitive sensors to detect chest expansion, avoiding the discomfort of traditional mouth or nose-attached devices.

The majority of devices designed to measure pulmonary data, specifically lung volume, are invasive; attaching to the mouth and/or nose making them difficult to wear for long periods of time. This device addresses that significant limitation.

The shirt employs a straightforward mechanical design centered on capacitive sensing technology. However, the system requires a detailed calibration process to function accurately, despite its mechanical simplicity.

This wearable technology represents an advancement in non-invasive respiratory monitoring, potentially enabling longer-term, more comfortable pulmonary assessments for patients and researchers.
