The act of approximation can be seen as a curve fitting of the experimentally observed values into the approximating function. The approximating function should be simple enough for ease ofputation and inversion and other mathematical treatments, for example, forputing a deriva- tive to find the sensor’s sensitivity.

Apr 25, 2001 · Holes can conduct current. A hole happily accepts an electron from a neighbor, moving the hole over a space. P-type silicon is a good conductor. A minute amount of either N-type or P-type doping turns a silicon crystal from a good insulator into a viable (but not great) conductor -- hence the name "semiconductor."

The effect of piezoresistance in germanium and silicon was discovered by C.S. Smith in 1954 [1].It was found that the resistance of a germanium or silicon filament changed when the material was stressed. The effect of piezoresistance is similar to the strain gauge effect in a metal material, but the differences between them are quite fundamental:
