Monitoring mental stress: Nanosheet-type tin oxide gas sensors provide quantitative measurement of emotional tension

By Lisa McDonald / October 28, 2022

Determining when to seek help for mental stress can be difficult. However, the recent identification of discernible odor substances that emanate from the skin during emotional tension may offer a way to quantifiably measure mental stress. Two researchers in Japan propose nanosheet-type tin oxides could be used as gas sensors to detect these substances.
