ZigBee-teknikens möjligheter att trådlöst överföra EKG-signaler
In many clinical applications, it is desirable to transmit sensor information wireless. In earlier research, investigation transmit ECG signal using Bluetooth, was performed. However, when Bluetooth has some drawbacks it is of interest to investigate alternative methods, one such method is ZigBee. Bluetooth has higher data rate speed (1Mbps) than ZigBee (250kbps). However, Bluetooth consumes more power. ZigBee uses in applications where low power consumption is important compared to high data rate. For industrial purposes, ZigBee is used in sensors and control unit technology. For medical treatment ZigBee can be used for patient monitoring.The aim of this work is to investigate if it is possible to wireless transmit an ECG signal with ZigBee-technology.The result shows that an ECG signal can be transmitted by using ZigBee. Since ZigBee is designed for low power consumption, the Zigbee-module must be set in passive mode in most of the time.
