What is Wearable Stress Level Meter about?

This document describes a stress meter circuit that uses variations in skin resistance to detect and indicate different levels of stress. The circuit uses touch pads on the back of a wrist-worn device to sense voltage variations from the skin which are amplified and fed into an integrated circuit. The IC drives LEDs in a logarithmic display pattern to visually indicate the stress level, and also triggers a buzzer at high stress levels. Adjustments can be made to set the sensitivity level when initially putt
