Could a smart wearable spot COVID-19 before symptoms start?
NCT ID NCT05035420
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This pilot study tested a noninvasive wearable device that measures breathing, heart rate, body temperature, and oxygen levels. Researchers wanted to see if it could help screen for and monitor respiratory infections like COVID-19. Forty healthy adults performed breathing tasks while the device was compared to standard monitors. The goal was to validate the device's accuracy, not to treat or diagnose disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- noninvasive multimodal biosensing device
- What this could lead to
- If successful, this device could offer a simple, wearable way to screen for respiratory infections and monitor recovery at home.
- What could go wrong
- This is a very small pilot study with only 40 healthy adults, not patients. It tests the device's accuracy in a lab, not real-world use. The device may not work as well in sick people or outside controlled conditions.

* INCLUSION CRITERIA: In order to be eligible to participate in this study, an individual must meet all of the following criteria: * Provision of signed and dated informed consent form. * Stated willingness to comply with all study procedures and availability for the duration of the study. * Male or female aged 18 years or greater. * In good general health as evidenced by medical history with no signs of cough, sneeze and upper respiratory symptoms. * Body temperature in normal range (afebrile, temperature \< 100.4 (Infinite) F) on the day of the experiment. EXCLUSION CRITERIA: * Any skin disease. * Fever (Temperature greater than or equal to 100.4 degrees F). * Any past or present cardiovascular or pulmonary diseases. * Known adverse reaction to latex. * Any medical condition that, in the opinion of the Principal Investigator would preclude the inclusion of a patient onto this research study. * Unable or unwilling to give informed consent. * Individuals with known respiratory conditions. * Individuals who are currently taking medication that may cause methemoglobinemia such as nitrates derivatives, sulfonamides, dapsone, phenacetin, phenazopyridine, some local anesthetics such as prilocaine, topical anesthetics such as emla cream, benzocaine. * Individuals with history of seizure. * Smokers and those on narcotics. * Pregnant women are excluded due to risk associated to hypercapnia risk
