AbstractArtificial limb control (ALC) system is a tool for helping patients to control their prosthetic limb.

To bring the most safety and the most convenience to the patients, a wireless

interface between the prosthesis and PC is required. In this thesis, the possibility to integrate

the wireless module to the ALC system was investigated. The available wireless

modules in the market was compared and selected. Bluetooth and WiFi technology was

studied. Selected WiFi and Bluetooth modules were tested by testing protocol to evaluate

the performance and the limitation of the modules. A hardware for implementing

both wireless modules was prepared and built. The wireless solution was integrated into

the ALC system and tested with a full recording session in BioPatRec platform. WiFi

allowed the raw EMG signal to be transmitted correctly. In contrast, Bluetooth is not

suggested for transmitting raw EMG signals for more than 4 channels or 256 kbps.

However, it has been proven that for data rate up to 128 kbps, Bluetooth works correctly

and may be alternatively solution for transmitting the signal feature instead.
