Under this consideration it is important to know the value of these parameters on the PLZT material manufactured due to the handling, and the results of Table 1 indicate that the material has a hardness value of 5.2 GPa with a deviation of 0.9, while the elastic modulus measured was 125 GPa with a deviation of 2, measured from the relation [mu] = [rho] * [[epsilon].sup.2] where, [mu] is the elastic modulus, [rho] is the experimental specific density in the material, and e is the measured speed sound in the material.
Although the aim of this study is not to analyze the effect of porosity in the electrical properties of PLZT materials, it is important to note that the porosity and shape are important factors in the manufacture of ferroelectric materials due to their application as biological sensors [9].
The key challenges with PLZT technology are cancelling the effects of ambient light, accommodating different skin conditions and colors, and dealing with physical motion artifacts.
By using solid state reaction technique, it is possible to make advanced PLZT ferroelectric ceramics with platinum wire implanted considering that platinum implant supports sintering temperature conditions due to its high melting point.
The PLZT ceramic implant has several applications in biomedical engineering and physics as it can capture various phenomena such as acoustic, mechanical, electrical, and optical [7].

In the case of the experimental phase data, the range of relative cavity length, in which the phase of (2)fits with the experimental data, is increased at least 500 [micro]m, when PLZT detector is used instead of the PVDF detector (see Figures 3 and 5).
It is common that, in PPE experimental setups, where a PVDF sensor is used, it is necessary to use a preamplifier before the PPE signal is sent to the lock-in amplifier [3, 8], while, in the proposed experimental setup with PLZT as sensor, this device can be omitted due to the high PPE signal provided by the PLZT detector.
PLZT hardness prevents the deformations that in thin PVDF sheets occur due to the sample weight; these deformations could add a piezoelectric effect in the measurement.
Another advantage of the ceramic PLZT over PVDF, for future studies, is the highest temperature range of operation, 80[degrees]C for PVDF and 180[degrees]C for PLZT, which allows obtaining thermal parameters at higher temperatures.
