Research status of assessment of mental fatigue based on HRV
Mental fatigue is a complex psychological and physiological phenomenon that can significantly impact an individual's overall well-being and performance.Effective assessment of mental fatigue is crucial for maintaining optimal health and productivity.Heart rate variability (HRV) has emerged as a valuable tool for evaluating mental fatigue due to its ability to provide detailed insights into the autonomic nervous system activity.While there is a growing body of research on the use of HRV for mental fatigue assessment,a comprehensive review of the current literature is warranted.This article reviews the research progress of mental fatigue assessment using HRV.Firstly,it discusses the various methods for analyzing HRV in the context of mental fatigue assessment,including the use of electrocardiogram(ECG),photoplethysmography (PPG),and ballistocardiogram (BCG) signals.The technical principles,advantages,and limitations of each signal type for assessing mental fatigue are elaborated upon.At present,the more mature method is to use ECG signal.Although there are few studies on BCG signal in the field of mental fatigue assessment,its acquisition process can be unconstrained and has a wide application prospect.Secondly,the mental fatigue assessment equipment based on ECG,PPG and BCG signal is summarized and compared.These devices are divided into wearable devices and non-wearable devices.The application scenarios of the two are different.Wearable devices are more mature than non-wearable devices.Finally,the article proposes strategies to address current challenges in mental fatigue assessment,aiming to enhance the accuracy and effectiveness of future assessment techniques.By improving the monitoring and evaluation of mental fatigue,individuals can better manage their mental health and optimize their work performance.
