Abstract: A wearable objective pain measuring device includes a headband configured to be worn by a user on the user's head. The device includes one or more sensors in the headband, including one or more of: a sweep impedance profiling sensor to collect data reflective of activity of corrugator supercilia during a pain session; an electromyography sensor to collect data signals from a brain that reflects pain perception; a photoplethysmogram sensor configured to collect data regarding changes in hear rate and heart rate variability due to pain state; or a galvanic skin response sensor configured to collect data related to changes in sweat gland and skin conductance due to a pain state. The device includes a pain quantification pipeline to objectively quantify pain based on data from the one or more sensors. The device includes an output device configured to output an objective pain quantification based on quantifying pain.
