Fatigue Testing of Wearable Sensing Technologies: Issues and Opportunities [PDF]
Materials, 2021 Standards for the fatigue testing of wearable sensing technologies are lacking. The majority of published fatigue tests for wearable sensors are performed on proof-of-concept stretch sensors fabricated from a variety of materials. Due to their flexibility and stretchability, polymers are often used in the fabrication of wearable sensors.

Fatigue Scales and Chronic Fatigue Syndrome: Issues of Sensitivity and Specificity
Disability Studies Quarterly, 2011 Few studies have explored issues of sensitivity and specificity for using the fatigue construct to identify patients meeting chronic fatigue syndrome (CFS) criteria. In this article, we examine the sensitivity and specificity of several fatigue scales that have attempted to define severe fatigue within CFS. Using Receiver Operating Characteristic (ROC)

Brain Fatigue is a Critical Issue [PDF]
International Physiology Journal, 2019 The brain is one of the most complicated body segments which processes almost all activities in human body. Excessive physical and mental overloads can cause brain fatigue and may put the brain health at risk of various disorders. Strategies such as reducing the workloads and performing mediation and walking provide opportunities for brain to relax and
