Electrodermal Activity (EDA) Stress Sensor

Interactive 3D model of a wrist-worn EDA/GSR biosensor: sweat-gland recruitment drives skin conductance through a tonic baseline plus bi-exponential phasic responses, exactly as a Fitbit Sense or Empatica sensor measures stress.

A wrist-worn wearable measures stress not by reading emotion directly, but by passing a tiny current between two skin electrodes and tracking how conductive the skin becomes as sweat glands fill. This simulator models that mechanism from the gland up: hundreds of individually instanced eccrine sweat glands on a 3D wrist patch each carry their own recruitment threshold, switching on as sympathetic arousal rises and producing the tonic skin-conductance-level drift and bi-exponential skin-conductance-response spikes a real EDA sensor reports. Drive arousal and ambient temperature, trigger a startle event, and watch the live conductance trace, tonic baseline, SCR rate and recruited-gland fraction update exactly as a Fitbit Sense or research-grade GSR band would.
