A wireless bipolar body electrode has been developed, taking into account the limitations posed by signal-to-noise ratio, dimensions, wireless technology, limited power consumption and requirements for post-processing. A small set of wireless bipolar electrodes, placed at optimal locations on the body surface, are connected into a network that is able to acquire real-time data. Measured signals, sampled with local frequencies of different electrodes, are synchronized to a global clock. Thus, complex post-processing that requires signals aligned in time is enabled. As an interesting example, a standard 12-channel ECG synthesis from a small network of three wireless bipolar electrodes is shown.
