Abstract

A bioelectric interface for monitoring, detection and transmission of detected ECG data is provided comprising a sensory system for detecting bio-physiological measurements utilizing spatially resolved potential profiles obtained from a localized cluster of sub-electrodes to form constituent sets of miniature sensor arrays. Using only a single macro-electrode, two or more sets of sub-electrode arrays are used to measure bipolar spatial gradients obtained from measured cardiac potentials. The sets of sub-electrodes containing the clusters are optimized to attain measurable gradients of diagnostic value. A minimax procedure allows bio-potential sensory acquisition through a bi-directional digital steering process, which essentially comprises monitoring, detection, selection, grouping, recording and transmission of ECG waveform characteristic data.
