Reviewer 1 Report
The authors have shown many results and experimental data in their study Comprehensive numerical analysis of a porous piezoelectric ceramic for axial load energy harvesting. I recommend a minor revision and some comments to improve before final acceptance.
1. In the introduction, some works need to be added like Nano Energy 100, 107514, 2022 and Sustainable Materials and Technologies 32, e00396, 2022
2. The authors should also consider the bending angle-based electrical output and show some modeling of how the flexoelectric effect can also influence the measurement.
3. The effect of different loads on the sample needs to be investigated?
4. The authors did not show any current profile data that need to be included in the manuscript
5. English grammar errors need to be removed carefully.

Reviewer 2 Report
The work by Rakesh et al. reports the numerical analysis of a porous piezoelectric ceramic energy harvester. Overall, I am satisfied with the results and the discussion. However, the organization and presentation of the work should be improved as this manuscript reads a bit like a lab report. The conclusion part is like a patchwork of the results of each part. I suggest the authors reorganize the manuscript and highlight the most important finding of this work.

Reviewer 3 Report
In the paper " Comprehensive numerical analysis of a porous piezoelectric ceramic for axial load energy harvesting " the authors present an interesting PEH configuration followed by a FEM simulation.
The paper is extremely well developed respecting all the rules of a high-level academic presentation.
The generated power is not well specified in the paper being critical, the measurement mode is not specified. It does not follow from the experimental setup that it was actually measured experimentally. It would be interesting to see how the impedance of the investigated system changes depending on the porosity and what would be the optimal value of the load resistance.
If the power has not been measured experimentally and has been calculated in the simulator then and without this measurement the submitted work can be considered for publication in this form.
