1. A measurement system to detect pain response in a patient, the measurement system comprising:

  • one or more patient sensors, disposed proximate to the patient, at least one of the patient sensors having at least two capacitive elements positioned on opposite sides of tissue of the patient;

    a capacitive system configured to measure a capacitance signal for the tissue of the patient, using at least one of the one or more patient sensors;

    a patient monitor configured to measure an electrical signal representing brain activity of the patient, using at least one of the one or more patient sensors; and

    a processing system configured to determine pain metrics based at least on the capacitance signal and the electrical signal, and determine a pain response of the patient based at least on the pain metrics and pain calibration information for the patient.
