Live demonstration: A wearable wireless ECG acquisition and specification system

摘要

This demonstration will present a wearable and wireless bio-signal acquisition and classification system that is specialized in electrocardiogram (ECG) monitoring. The system comprises the design and implementation with three parts, namely, an analog front-end (AFE) circuit, a digital signal processor (DSP) and the Bluetooth module. The AFE is used to detect the ECG signal and DSP is used to classify the signal and control the Bluetooth communication. At last, the real time ECG signal would be shown on the screen of the mobile phone. The system is implemented in a TSMC 0.18µm 1P6M process under supply voltage of 1.2 V. With two PR44 zinc-air batteries of 605mAh as the power supply, the system can be operated about 2 days.
