Numerical Analysis of Signal Response Characteristic of Piezoelectric Energy Harvesters Embedded in Pavement

Round 1

Reviewer 1 Report

Thank you for your investigation.

1. In my opinion, Figure 4. should be correct. Time range from 0.0135 to 0.2565 and from 0.4995 to 0.6615 is not informative.
2. I did not find the boundary condition for simulation from the text. Fixed constraints (I guess bottom part of the pavement), maybe a slider condition from the sides, or infinite domain from pavement's sides or similar.
3. You are concluded: 3) The power generation is a combination of the 3-1 mode and 3-3 mode. By comparison, 3-3 mode has high power generation capacity, but its corresponding range is small, while 3-1 mode has the opposite effect... > polarization of piezoceramic, which you used, by the thickness (d33). According to the experiments, the main pavement deformation close to the bending mode, I think piezoceramic orientation inside the pavement should have an influence on the EH efficiency, isn't it?!

Reviewer 2 Report

The novelity of presented results with earlier developments of authors  must be clerfied.

The finite element matematical model  is upsent. Presenting of values of specifed matrices without formula is not correct.

Working modes  of pjezoelectric materials are not clearly described. Using of notations 3.1, 3-3 needs to be motyvated motivation.e not clearly described.  

Comments on the future work, dont belong to conclusions.

Reviewer 3 Report

The paper is well structured and written. The conclusions are supported by the analysis of the simulation data presented and therefore the paper can be accepted for publications as it is. I only suggest to revise a couple of sentences that sound excessive to me. I will send a pdf file with few suggestions for the authors.
