The Berkeley Tricorder: Ambulatory Health Monitoring

Abstract

We developed and tested the Berkeley Tricorder, a health monitoring device capable of measuring a subject's ECG, EMG, Blood Oxygenation, Respiration (via Bioimpedance), and motion--almost equivalent to the feature set of a hospital bedside patient monitor. Our focus has been a highly integrated design incorporating the radio and all associated circuitry on a single PCB. The device stores data locally on microSD flash and/or transmits via Bluetooth. We will also discuss a strap we have developed which utilizes reusable electrodes for data acquisition as well as a desktop and mobile application for real-time data telemetry. We have evaluated the efficacy of the device in recording ambulatory data from 24 subjects and found the data acquisition relatively free of motion artifacts.
