Whether in electronics, mechanical engineering, or biology, miniaturization brings demands for dimensional accuracy. Simply adopting a downsized standard method from the big world won’t work. The conventional way of getting accurate micromeasurements is to move the object being measured past a measuring probe using piezo actuators. The probe operates in a manner similar to a coordinate-measuring machine, returning a signal when contact is made. The position of the measured object is then read from the piezo drive. Several readings taken at different points determine the object size.
