A Wearable Device for Early Detection of Covid-19 Symptoms
Written on
Chapter 1: Introduction to Wearable Technology
In the ongoing fight against Covid-19, innovative solutions are being developed to enhance our response to the pandemic. One such breakthrough is a flexible, skin-like sensor designed to be worn just below the suprasternal notch—the indentation at the base of the throat. This device continuously monitors vital signs such as body temperature, heart rate, and respiratory activity, including cough detection.

Section 1.1: The Development of the Device
Created by a team at Northwestern University and the Shirley Ryan AbilityLab in Chicago, this wearable technology sets itself apart from conventional devices like the Fitbit or Oura smart ring. Most of these traditional wearables track health metrics from the wrist or finger, whereas the Northwestern team, led by bioelectronics expert John Rogers, PhD, aimed to develop a sensor that could more accurately monitor respiratory sounds directly from the throat.
Subsection 1.1.1: How It Works
This skin-like device uses sophisticated algorithms to detect and evaluate cough patterns in real time. By transmitting data to a tablet, healthcare professionals can gain insights into the wearer’s health status. The researchers believe that tracking these cough patterns throughout the day—and noting changes over time—might enable early detection of Covid-19 symptoms.
Section 1.2: Current Applications
At present, this device is being utilized in research studies to monitor symptoms in healthcare workers and patients hospitalized with Covid-19 as their conditions evolve. However, it is not yet available for commercial purchase. A significant consideration remains whether consumers would be inclined to use such technology.
Chapter 2: The Role of Consumer Wearables
As the interest in wearable technology grows, companies are exploring the potential for their devices to predict Covid-19 cases. Recently, Fitbit released findings in the journal NPG Digital Medicine, indicating that their devices might be able to predict up to 21% of Covid-19 cases a day before symptoms appear, with a specificity of 90%.
