Key result
Wearable electronics for continuous heart rate variability monitoring provide a promising approach for assessing human physical and mental well-being, including stress and drowsiness.
Why the study?
Traditional ECG devices for HRV analysis are bulky and require hard wires, resulting in poor wearable experience during long-term measurement.
Wearable electronics offer a promising, less obtrusive alternative to traditional ECG for continuous HRV monitoring to assess physical and mental well-being.
Hypothesis-generating for wearable HRV monitoring in wellness; prospective trials needed before clinical adoption.
Heart rate variability (HRV) that can reflect the dynamic balance between the sympathetic nervous and parasympathetic nervous of human autonomic nervous system (ANS) has attracted considerable attention. However, traditional electrocardiogram (ECG) devices for HRV analysis are bulky, and hard wires are needed to attach measuring electrodes to the chest, resulting in the poor wearable experience during the long-term measurement. Compared with that, wearable electronics enabling continuously cardiac signals monitoring and HRV assessment provide a desirable and promising approach for helping subjects determine sleeping issues, cardiovascular diseases, or other threats to physical and mental well-being. Until now, significant progress and advances have been achieved in wearable electronics for HRV monitoring and applications for predicting human physical and mental well-being. In this review, the latest progress in the integration of wearable electronics and HRV analysis as well as practical applications in assessment of human physical and mental health are included. The commonly used methods and physiological signals for HRV analysis are briefly summarized. Furthermore, we highlighted the research on wearable electronics concerning HRV assessment and diverse applications such as stress estimation, drowsiness detection, etc. Lastly, the current limitations of the integrated wearable HRV system are concluded, and possible solutions in such a research direction are outlined.
