(a) Schematic illustration of the measurement setup with the fabricated sensor placed next to a commercial strain gauge on the surface of a stainless-steel plate. (b) Comparison of the voltage output from the fabricated sensor with the strain from the commercial strain gauge. (c) Almost identical polarization–voltage hysteresis curves of the piezoelectric strain sensors obtained before and after transfer printing demonstrate the effectiveness and applicability of the technique.
