Does the CardioGuard brassiere-based ECG sensor provide reliable ECG monitoring and user comfort during daily activities?
The CardioGuard brassiere-based ECG sensor demonstrates reliable QRS detection and user comfort during daily activities, supporting its potential for unobtrusive smartphone-based healthcare monitoring.
We propose CardioGuard, a brassiere-based reliable electrocardiogram (ECG) monitoring sensor system, for supporting daily smartphone healthcare applications. It is designed to satisfy two key requirements for user-unobtrusive daily ECG monitoring: reliability of ECG sensing and usability of the sensor. The system is validated through extensive evaluations. The evaluation results showed that the CardioGuard sensor reliably measure the ECG during 12 representative daily activities including diverse movement levels; 89.53% of QRS peaks were detected on average. The questionnaire-based user study with 15 participants showed that the CardioGuard sensor was comfortable and unobtrusive. Additionally, the signal-to-noise ratio test and the washing durability test were conducted to show the high-quality sensing of the proposed sensor and its physical durability in practical use, respectively.
Kwon et al. (Tue,) conducted a observational in Healthy volunteers (n=15). CardioGuard brassiere-based ECG sensor vs. Reference ECG Holter monitor (Shimmer 2R) was evaluated on Average QRS peak detection ratio (RDR) across 12 daily activities. The CardioGuard brassiere-based sensor reliably measured ECG during 12 representative daily activities, detecting an average of 89.53% of QRS peaks compared to a reference Holter monitor.
