The use of wearable sensor technology for athlete training monitoring is growing
exponentially, but some important measures and related wearable devices have received …

Respiratory rate (RR) is an important physiological parameter whose abnormality has been
regarded as an important indicator of serious illness. In order to make RR monitoring simple …

In this article, we present current methodologies, available technologies, and demands for
