By detecting cardiovascular ailments and helping assess overall cardiac health, wearable electrocardiograms save lives, not to mention exorbitant hospital care costs. Researchers now present a novel wearable electrocardiogram patch for enhanced point-of-care diagnostics. The study focused on the advantages of using active dry electrodes for ECG signaling, and they created a compact, lightweight, gel-free hexagonal-shaped ECG patch. The configuration was then integrated with wireless Bluetooth communication for remote sensing capabilities.
