The Patent Description & Claims data below is from USPTO Patent Application 20080091098, Measurement of autonomic function.

1. An article of manufacture, comprising: at least two sensors having an offset potential of below about +/-1.0 mV; and a data gathering device connected to the sensors capable of measuring the voltage difference between the electrodes.

2. The article of claim 1, wherein at least two of the sensors possess a sensing side having an AgCl coating on a Silver substrate

3. The article of claim 1, wherein the offset potential is below about +/-0.5 mV.

4. The article of claim 1, wherein the offset potential is about +/-0.01 mV.

5. The article of claim 1, wherein a pre-applied conductive gel is disposed on the sensing side of the sensors.

6. The article of claim 1, wherein the sensors are connected to a data gathering device via lead wires across a resistor of 0.5 to 500 k-Ohms.

7. The article of claim 1, wherein the sensors are less than 20 mm in diameter.

8. The article of claim 1, wherein the sensors are 10 mm in diameter.

9. The article of claim 1, wherein the sensors are disposable.

10. The article of claim 1, wherein the sensors have an adhesive collar.

11. A device suitable for detecting a shift in the autonomic nervous system, comprising: a sensor, wherein said sensor is utilized with at least one other sensor, and said sensor has an offset potential of less than 0.5 mV when used with said other sensor.

12. The device of claim 11, wherein the sensors have an exposed-to-gel sensing side of silver chloride coated silver.

13. The device of claim 11, wherein the offset potential is below about +/-0.5 mV.

14. The device of claim 11, wherein the offset potential is about +/-0.01 mV.

15. The device of claim 11, wherein a conductive gel is pre-applied to the sensor.

16. The device of claim 11, wherein the sensor is less than 50 mm in diameter.

17. The device of claim 11, wherein the sensor is less than 20 mm in diameter.

18. The device of claim 11, wherein the sensor is about 10 mm in diameter.

19. The device of claim 11, wherein the sensor is disposable.

20. The device of claim 11, wherein the sensor has an adhesive collar.

21. A method for detecting a shift in the autonomic nervous system, comprising: affixing at least two sensors having a paired offset potential of less than 0.5 mV to contralateral sides of an animal or human; and measuring the voltage difference between said sensors.

22. The method of claim 21 wherein the voltage differential is measured continuously.

23. The method of claim 21, wherein the voltage differential is recorded, displayed or both recorded and displayed by a data gathering device.

24. The method of claim 21, wherein the voltage differential is correlated to a Visual Analogue Scale and self-reported pain.

25. The method of claim 21, wherein the method is used to diagnose conditions of altered ANS function.

26. The method of claim 21, wherein the method is used to ascertain the effectiveness of medicine.

27. The method of claim 21, wherein the method is used on a human.

28. The method of claim 21, wherein the method is used on an animal.

29. The method of claim 21, wherein at least one sensor is affixed to each hand of a human.
