DeltaP: Non-Invasive Urine Output Monitoring via Bioimpedance
- Program: Biomedical Engineering
- Course: EN.580.X12 BME Design Team
- Year: 2026
Project Description:
Acute kidney injury (AKI) is a condition that causes 1.7 million deaths globally each year. Urine output (UO) is the earliest AKI biomarker, but it is currently measured via Foley catheterization, which causes ~1 million CAUTIs annually in the U.S., while noninvasive detection alternatives remain inaccurate. We aim to meet the need for a reliable noninvasive UO-monitoring system by designing a wearable bioimpedance device that uses surface abdominal electrodes to continuously estimate UO in real time, targeting ±0.075 mL/kg/hr accuracy for KDIGO-compliant AKI staging without catheterization.
