Noise performance of textile‐based dry ECG recording electrodes

Abstract This study reports attempts to characterise the noise properties of un‐gelled, textile‐based electrodes intended for use in ECG recording in wearable garments. Measurements were made using very low noise operational amplifiers and with mains power supply interference eliminated from the rec...
