Flexible sensors for wearable cardiac monitoring system: a review

Cardiovascular disease (CVD) is the leading cause of death worldwide, and electrocardiogram (ECG) detection is one of the methods for cardiac monitoring. Flexible wearable cardiac monitoring systems provide more comfortable technical solutions for long-term ECG acquisition and analysis. This paper analyzes the application classifications of flexible wearable sensors, reviews relevant technologies for flexible wearable ECG sensors, and statistically analyzes common materials and analytical algorithms used in such sensors. In the future, flexible wearable ECG sensors will be more accurate and durable in order to provide clinical-grade heart health data.
