ZigBee-based wireless transmissions interface incorporated to an FPGA embedded system

Abstract

An application that uses ZigBee modules to transmit signals of ECG (Electrocardiogram), Intraventricular Pressure (IVP) and Intraventricular Volume (IVV) from a Conductance Catheter System (CCS) is presented. Wireless interface is developed using ZigBee modules. One of these modules ('COORDINATOR') is connected to a PC and receives signals from the remote module. The last, confi gured as an 'END DEVICE', collects signals from the digital CCS. Data including biomedical signals are previously processed using a Field Programmable Gate Array (FPGA) device. ZigBee technology ensures robust communication with very low power consumption, a feature that makes it suitable for implantable biomedical devices.
