Exploring the efficacy of Piezoelectric-based sensory systems for heart rate monitoring in differentiating stress vs. relax conditions

Stress has diverse effects on human physiological reactions, and one such effect is on heart rate (HR). The established methods to acquire HR is by electrocardiogram (ECG) and photoplethysmogram (PPG). ECG electrodes need to be placed on the chest, which can cause inconvenience and is...
