Multichannel Wireless Bioelectric Potential Measurement: State of the Art and Applicability for BSP Mapping

High-resolution multichannel bioelectric potential measurement is required for diagnostic methods of various cardiac and brain diseases. The systems previously developed in our lab are streaming measured data to PC over an optical USB cable. Disadvantages of these systems are that the personnel should be careful when manipulating with the cables and difficulty of mounting the electrodes on the patients. New wireless standards enable high data rate transmission. The newest wireless Bluetooth and Wi-Fi standards were studied and specifications of these standards were evaluated for possible usage in multichannel battery powered measuring systems.
