Design of a Wireless Data Acquisition Platform Using Bluetooth Low Energy Protocol
Papafotis Konstantinos, Ioannis Lalellis
Abstract
This diploma thesis presents the design and implementation of a system which collects weak biomedical signals (EEG, ECG etc) and transmits them wirelessly to nearby terminals. Initially, the main structure and the individual blocks are introduced and briefly described. Next, two of the most popular wireless transmission protocols personal space (WPAN), the ZigBee and Bluetooth Low Energy protocol are studied thoroughly and compared in order to decide the one that fits best to specifications. The thesis continues with the description of each basic functional unit and their interconnection. Moreover, to allow communication with remote devices, specific antenna structures are studied. Finally, we present the design and manufacturing of the printed circuit board (PCB) and the results of the experimental process/measurements.
