1. When various gases are passed over a polycrystalline ceramic, its electrical resistance changes . 2. The value of the charge transfer resistance changes with the overpotential. 3. This resistance change is measured and processed into temperatures which can be represented graphically. 4. Some metals display piezoresistivity that is much larger than the resistance change due to geometry. 5. When the temperature changes, the resistance changes , quite dramatically. 6. Volcanic eruptions may be detected by visible ash layers, acidic chemistry, or electrical resistance change . 7. They read back pressure, and take into account resistance changes downstream from the needle valve. 8. A "'force-sensing resistor "'is a material whose resistance changes when a force or pressure is applied. 9. These sensors were shown to have high sensitivity, with resistance changes of three orders of magnitude. 10. This resistance change is measured and processed into temperatures which can be used to create an image.
