The design of a mobile multi-channel bio-signal measuring system for rehabilitation purposes

For any paralyzed or amputated patient rehabilitation is a necessary procedure. Rehabilitation for paralyzed patients is very important because of health protection and for amputated patients it helps to learn to control prosthetic. This paper presents the design of a mobile bio-signal measuring system. The goal of the project is to develop a robust mobile measuring system which can be used in several rehabilitation programs. The system is capable to measure ECG, EEG, EMG signals through multiple channels. At the moment the main scope is to measure EMG signals on the arm, and to optimize the signal condition and data compression through wireless data transmission. The current circuit and system designs are presented and a possible solutions for signal pre-processing is suggested.
