The first application of the piezoresistive effect was metal strain gauges to measure strain, from which other parameters such as force, weight, and pressure were inferred (see Figure 2.4).

Most the resistance change in metals is due to dimensional changes: under stress, the resistor gets longer, narrower, and thinner

piezoresistivity …
