A Highly Integrated Hardware Design Implemented on FPGA for a Wireless Healthcare Monitoring System

Abstract

In this paper, we present a highly integrated hardware design providing several biomedical signals processing in a wireless healthcare monitoring system. This system includes a biomedical front-end circuits acquires and digitizes biomedical data such as electroencephalogram (EEG) and electrocardiogram (ECG), a control interface to connect and control the biomedical front-end circuits, a real-time online recursive independent component analysis (ORICA) engine to extract artifacts automatically of brain electroencephalogram signals, a heart rate variability (HRV) analysis engine for processing ECG signals and a display platform to display the physiological data. A commercial Bluetooth module is used to transmit wirelessly between the processor and the display platform. This system can provide several physiological data such as blood pressure, oxygen saturation and body temperature. This hardware design implemented using field-programmable gate array (FPGA) and schedule for fabricated using TSMC 90 nm CMOS technology.
