FECG: A Flexible Holter for Ambulatory Heart Rate Monitoring

Brain-like artificial intelligence technology has been developing continuously, and its practical application has been widely popularized. Since the effect of brain-like AI technology is mainly reflected in the interaction with the user, it is necessary to collect various physiological indicators of the user during the interaction process in order to test the specific feelings of the brain-like AI technology on the user, such as emotional changes or physiological reactions. In order to realize this need, we designed and fabricated an almost completely flexible wearable ECG monitoring system using textile electrodes and Flexible Printed Circuit Board (FPCB) technology: FECG (Flex Electrocardiogram System). The FECG has been tested by user experiments and is capable of delivering reference-level physiological data (3 uV equivalent input noise, 85 dB common mode rejection and 500 Hz sampling rate) that meets medical standards while achieving long-term wearability and high comfort. The construction of this system can minimize the interference factors, while testing the user’s ECG data more conveniently and accurately, providing a detailed test basis for constructing a reasonable interaction effect.
