Live Demonstration: A Wireless Multi-channel Physiological Signal Acquisition System-on-Chip for Wearable Devices

Abstract

A wireless ExG sensor tag with a multi-channel physiological signals acquisition system is demonstrated. The system contains a mixed-signal system-on-chip (SoC) and Bluetooth Low Energy (BLE) chip for data analyzing and wireless transmission. The demonstration presents acquisition of different physiological signals, such as electrocardiogram (ECG), electrooculography (EOG), surface electromyogram (EMG) being real-time recorded and wirelessly displayed on tablet. The power-efficient ExG wireless tag can be easily achieve 12 hours with 200mA battery for continuous recording of ExG signals in healthcare applications.
