Temperature-Independent High Precision Resistor and Expansion Sensor (nanoNi@C®)
A combination of metal and carbon layers enables to combine the two main characteristics “high expansion sensitivity” and “temperature-independence of the resistor” in one single material. The negative temperature coefficient of carbon is balanced by insertion of metal (nickel) with a positive temperature coefficient, leading to the possibility of producing a material using very low temperature dependence. This new technology offers temperature-independent (± 11 ppm/K in measuring range of 25-200 °C) resistors that show a strong modification of electric resistance depending on the material’s expansion.
