Abstract
A method to evaluate an electrochemical skin conductance (ESC) of a user body using a measurement device, the measurement device including a pair of electrodes including an anode and a cathode, a direct voltage source, a measurement resistor, control circuitry configured to set the electrical resistance value of the measurement resistor and to set the value of the direct voltage, wherein the method includes, by the control circuitry pre-stabilizing during a pre-stabilizing period, measuring during a measurement period following the pre-stabilization period.
Claims20
A method to evaluate an electrochemical skin conductance, ESC, of a user body using a measurement device, the measurement device including
- a pair of electrodes comprising an anode and a cathode configured each to be in contact with the user body,
- a direct voltage source configured to apply a direct voltage to the anode, wherein a value of the direct voltage is variable,
- a measurement resistor configured to determine a current value flowing through the used body, wherein an electrical resistance value of the measurement resistor is variable amongst a predetermined range, and
- control circuitry configured to set the electrical resistance value of the measurement resistor and to set the value of the direct voltage,
- the method comprising, by the control circuitry:
- pre-stabilizing during a pre-stabilizing period, the pre-stabilizing comprising:
- setting the electrical resistance value of the measurement resistor at a pre-stabilization value,
- applying a pre-stabilization voltage at the anode during the pre-stabilizing period, and
- measuring during a measurement period following the pre-stabilization period, the measuring comprising:
- applying at least one measurement voltage at the anode, and
- generating ESC values using at least one voltage measurement at the anode and/or the cathode obtained during the measurement period.
