a composite piezoelectric apparatus has a sacrificial base and pillar array. Different volume percents of piezoelectric material are used in the sacrificial base and pillar array. The first volume percent is about 30-40% of first piezoelectric material, and the second volume per cent is about 50-65% of the second piezoelectric material. The first and second piezoelectric materials can be the same or different piezoelectric material including, but not limited to, lead zirconate titanate (PZT), lead niobium titanate (PNT), and lead scandium niobium titanate (PSNT). In one particular example, not intended to limit the invention, the first volume percent is about 36% of PZT, and the second volume percent is about 60%-65% of PZT .
With the above composition, I want to know the leading the manufacturers of the composite piezoelectric apparatus.
Thank you in advance !!
You can search for the relevant products in the following website. They have variety of piezoelectric products and cover wide domain.

Hello P. K. Dubey Sir,
Thank you so much for your response.
I have visited above the link. Yes, it is quite helpful.
Sir, I want to know, that how can I identify the volume percentage of the material used in the piezo device.
Do Qualcomm, Intel, Nvidia etc chip producing companies also manufacture the piezo devices?
Thank you once again for your answer.
Here are a couple more suppliers. Not sure that this answers your question regarding composition. These things tend to be very closely guarded. These all have very different constructions but tend to be around the 1-15 MHz resonance with broadband widths

Hello Chris Gregory ,
Thank you so much for your response.
I will definitely visit these links.
Thank you ,

Hello Richa Singh,
Innovia Materials is a leading piezoelectric composite manufacturer (https://www.innoviamaterials.com/about/?125.html). Pillars of 1-3 or 2-2 types are made out of a piezoelectric blank to optimize electromechanical coupling with high aspect ratios. Specifically in your referred invention, I think the second phase being another form of piezoelectric ceramics rather than polymer is because the inventors want to take advantage of both piezoelectric performance while separating their electrodes and exciting signals.
