The choice between the two is usually based on whether the measurement is static (strain gauge) or dynamics (piezoelectric). The choice between the two is usually based on whether the measurement is static (strain gauge) or dynamics (piezoelectric).
Main differences between the two are shown in Figure [1](#orgc54ca38). Main differences between the two are shown in Figure [1](#org140fe11).
