The voltage regulated devices may require more frequent adjustments of the stimulation intensity as the charge that they deliver changes as the skin / tissue resistance changes.
22.
NO 2 gas acts as a strong oxidizing agent to the emeraldine form of polyaniline nanofibers, which causes resistance changes greater than three orders of magnitude at 100 ppm.
23.
It shows that both doped and dedoped polyaniline nanofibers can be used for detection of hydrogen gas through resistance changes, but the dedoped nanofibers were more stable and had better reproducibility.
24.
But when the Berkeley group put a nanotube in a vacuum chamber and measured its chemical resistance after exposing it to oxygen, " the resistance changed in less than a second,"
25.
:: : : If you need proof about it being a small increase in resistance change and thus a small strengthening / weakening effect, I can dig up a ref for that.
26.
Second, they can be used in conjunction with Joule heating ( also called self-heating ) : If a large current is running through the resistor, the resistor's temperature rises and therefore its resistance changes.
27.
The PulseCO method overcomes the limitations of the more historic approaches that were reported to be compromised by the variable contribution of the arterial reflected wave and resistance changes that can occur in peripheral arteries.
28.
While most of them will likely always be against, a change is possible if their resistance changes from being against and having big problems with it, to being against and being able to tolerate it.
29.
Basically GMR enables a large resistance change in material stacks with differing magnetic orientations because it takes more energy to cause electrons to flow through a magnetic domain if their 128.61.20.199 13 : 19, 14 November 2007 ( UTC)

Various constantan alloys and Karma alloys have been designed so that the temperature effects on the resistance of the strain gauge itself cancel out the resistance change of the gauge due to the thermal expansion of the object under test.
