In a study published in Applied Physics Reviews, researchers from RMIT University in Australia and Rajah Muthiah Medical College in India introduced an innovative wearable ECG patch designed for better diagnostics.
The researchers explored various electrode designs and materials to develop a compact, lightweight, and gel-free wearable ECG patch for point-of-care diagnostics. The study aimed to design more comfortable and durable dry electrodes for continuous monitoring instead of traditional wet electrodes that are prone to irritate the skin.
They investigated different electrode geometries and their influence on ECG sensing. Researchers found the hexagonal labyrinth-based electrode design created using gold to be the most suitable candidate among the designs evaluated. The researchers also developed a prototype of a wearable ECG patch with this electrode configuration and wireless communication capabilities.
The device showed promising results compared to a commercially available portable ECG monitor. This research has potential applications in remote healthcare, ambulatory care settings, and as a point-of-care and preventive medical device.
