The key technologies for realizing human sensing using human samples such as blood and saliva are biomarkers and biosensors. Chemical salivary test has overwhelming advantages over blood test in that it is intrinsically safe and test samples can be self-collected any time. Especially, salivary sensors will be practically applied to various human sensing as point-of-care testing (POCT). This review focuses on the current status and future prospects of diagnostic methodologies using saliva samples. Although attaining happiness and overcome stress are nearly universal goal, surprisingly little research has focused on how happiness can be increased and stress can be decreased. The direction of new applications for salivary sensors is discussed by introducing commercially available salivary tests for the detection of emotion and stress.
