Abstract

A diatrophic, bio-physiological interface is self-contained with onboard intensification, filtering, and signal processing and is wirelessly enabled (idio-electrode), with multiple sensory system for bio-physiological measurements, described herein utilizes spatially resolved potential profiles from a cluster of mini electrodes to form constituent sets comprising mini sensorial electrodes. The sets of sub electrodes containing the clusters are jointly optimized to attain measurable gradient of some diagnostic value. The present invention provides a distinct lead-free single electrode that is rotationally invariant with onboard Digital Signal Processor for arrhythmia detection, source encoding, and passive and active wireless transmission. Additionally, in one aspect of the present invention the lead-free idio-electrode bio-physiological adapter allows for utmost clinical operational freedom and dramatically obviates the needs for leads of any length that invariably encumber the acquisition and performance of electrocardiogram recordings of any sort. Additional disclosure pertains to: In-situ Real-Time Auto-Regressive Predictive ECG Analysis; Real-Time Patient-Event Reporting; Dynamic Multi-function External Interface; Device Charging; Capacitive Touch UI; A Priori Signal Integrity Verification; Inductive Mode Charging; Electrode/Enclosure Interface; Application of Predictive Analysis to Power Efficiency and Run-time Optimization; and Master-Slave Network Synchronization via Out-of-Band AC-coupled Potential.
