Overview

• The wearable wristband uses a pain-free microneedle array to continuously sample interstitial fluid for real-time glucose, lactate and alcohol measurements.
• An integrated ultrasonic sensor array and ECG electrodes monitor blood pressure, arterial stiffness and heart rate from wrist pulses.
• Validation studies demonstrated close agreement with blood glucose meters, continuous monitors, breathalyzers and blood lactate meters across multiple tests.
• The microneedle patch is designed for easy replacement to customize wear duration and minimize risks of allergic reactions or infection.
• The device was detailed in Nature Biomedical Engineering following a collaboration between research teams led by Joseph Wang and Sheng Xu at UC San Diego Jacobs School of Engineering.
