thrum
thrum is a maternal health system designed to monitor blood pressure continuously and discreetly throughout pregnancy and postpartum recovery. It aims to enable faster, more accurate diagnosis of hypertensive disorders — the leading cause of maternal mortality in industrialized countries.

Key Insights
Warning signs, such as nausea and a persistent headache, were always present — just overlooked or invisible.
Limitations of Blood Pressure Monitors
Blood pressure fluctuates throughout the day due to factors like stress, activity level, meals, sleep, and clinical settings. BP monitors will only capture in-the-moment readings, and may not reflect true average blood pressure, leading to under- or over-treatment.
Design Goals
thrum
thrum is an AI-supported monitoring system composed of a rechargeable ultrasound patch, a charging case, and a companion app.
Sticker Mounting Station
To get the double-sided sticker to adhere properly to the patch, there are two extrusions in the middle cavity to help with alignment.
More Accurate Readings
The ultrasound patch measures the levels of glucose, lactate, alcohol, and caffeine in addition to blood pressure. thrum’s AI automatically adjusts the readings using the data collected.
Adaptive, Ambulatory BP Tracking
Medical providers can adjust tracking frequency based on a mother’s health condition, increasing it when risks are higher.
Symptom Log and AI Assistant
The app lets mothers log symptoms to share with their OBGYN, while also contributing anonymized symptom profiles to a shared catalog for broader pattern recognition.
