Science behind the Moodmetric ring

Emotional sensations such as excitement, happiness, anger and joy often involve a physical response, such as the heart pulsating with fear or the stomach lurching from anxiety.

Many of these physical reactions are controlled by the sympathetic nervous system, a branch of the autonomic nervous system, which controls involuntary body responses such as blood flow and digestion. The sympathetic nervous system is activated with controlling the body’s fight-or-flight reactions. When facing a threat, these responses automatically prepare your body to flee from danger or face the threat head-on.

When experiencing an emotion the sweat glands in the palm react and skin conductance increases. This phenomenon can ne measured and is known as electrodermal activity (EDA), skin conductance response (SCR) or alternatively as galvanic skin response (GSR). The Moodmetric ring detects the changes in skin and shows the emotion level changes in relation to user´s personal threshold values.

The measurement has been used in scientific study for over a hundred years. The Moodmetric ring data has been verified against scientific equipment, indicating high correlation and thus the ring is a reliable EDA measurement device.
