The piezoresistive effect
in conductive polymer composites, particularly those filled with carbon black, has been documented as early as 1966  and several proceeding studies have examined their mechanisms and applications [9-11].
To perform ultrasound measurements, electrical signals produced in a generator are converted into mechanical oscillations with frequencies in the MHz range in an ultrasonic converter (transmitter) using the piezoresistive effect

It is interesting to note that MEMS technology established vis-a-vis the discovery of the piezoresistive effect
at Bell Laboratories in 1955 by Charles Smith is approximately the same 'age' as Integrated Circuit (IC) technology established vis-a-vis the semiconductor effect that was discovered at the same laboratory by Bardeen et al.
This intrinsic piezoresistive effect
is more than an order of magnitude more sensitive to strain than the extrinsic effect - elastic stretching - that metal strain gauges rely on.
