Stress gauges through saliva

Its name is Coroco Meter (translated as "Heart Measure" in Japanese), but in fact it is a device that allows regular testing of users' stress levels.

It is a unique invention by Professor Masaki Yamaguchi (Toyama University) and Japanese company Nipro for measuring a person's stress level only through saliva analysis.

Coroco Meter weighs only 190 grams (photo), has a digital screen and clear images of stress levels, considering the amount of amylase (or enzyme amylase) in saliva. To measure this level, the user places a test strip in his or her mouth to collect saliva, puts it in the meter and waits for a minute to know the result. The machine is priced at 167 USD, not to mention a lot of 20 sticks to get saliva for 29 USD.
