Johns Hopkins University students designed a wearable device that tracks sweat urea levels to provide a non-invasive alternative to traditional clinical testing. The team received the 2026 Dean's Design Award for Electrical and Computer Engineering for the project.
Why it matters
The project aims to simplify health monitoring by eliminating the need for frequent clinical blood and urine tests. This approach could offer a more convenient way to track health biomarkers in a non-invasive manner.
The device uses a color sensor to detect urea presence on a test strip, with results processed by a microcontroller and displayed via a Python-based dashboard. The study is currently pending clinical validation versus standard blood test benchmarks.
The players
Johns Hopkins University
Located in Baltimore, this private research university is known for its high-ranking engineering programs and medical research output.
Ryan Chan
He is an engineering student who collaborated on the design and development of the non-invasive monitoring device.
Fausto Kang
He is one of the student developers who contributed to the technical creation of the SweatSense technology.
Jason Konadu
He is a student team member who helped design the device to measure urea levels in sweat.
The details
Developed by Ryan Chan, Fausto Kang, and Jason Konadu, the SweatSense system captures sweat from the underarm using a specialized test strip. A custom 3D-printed enclosure shields the internal color sensor from ambient light to ensure accurate readings of urea concentrations.
Timeline
The SweatSense project won the Dean's Design Award in 2026.
The Big Picture
This project reflects the broader push toward decentralized, non-invasive health monitoring systems within the Johns Hopkins Whiting School of Engineering research initiatives. It follows a established pattern where academic engineering projects seek to bridge the gap between clinical diagnostics and daily patient convenience.
If successfully validated, this technology could offer patients a less intrusive method for regular health monitoring outside of a clinic. Residents in Baltimore and beyond may eventually see more options for managing their health markers without the burden of frequent blood draws.
The takeaway
Non-invasive monitoring technology continues to evolve as a potential solution for chronic health management. Future advancements in wearable sensors may eventually provide more seamless integration of diagnostic tools into daily life.
