Vibration Characteristics and Experimental Research of an Improved Bistable Piezoelectric Energy Harvester

Round 1

Reviewer 1 Report

the article is interesting, I ask for the answer to my comments before any kind of decision,

1- What is the maximum value of vibration that you designed ystem can support?

2- Please give more details about the used magnets (material, magnetic field value, weight of each magnet, etc).

3- if you develop something interesting. what is the price and added benefits of your prototype in comparison with those existing in the market.

4- please compare your results with other works in the literature.

Reviewer 2 Report

This paper presents an improved version of bistable piezoelectric energy harvester. Both simulation and experiments are conducted to demonstrate its effectiveness and comparisons are also made to show its superiority. The paper can be considered for publication after incorporating minor revisions:

1.       ‘but these methods pose challenges to the fabrication of materials and the stability of system operation’ – Why do those methods pose such challenges? How do those challenges come from?

2.       ‘Based on the research of the research group [27], this paper proposes …’ – why do the authors conduct the present research based on that study? What is advantage of that method to be based on? What is also its disadvantage to be improved in this work?

3.       What is the main motivation and contribution of the present work? This is not clearly illustrated in Introduction?

4.       There are many grammar mistakes in the text, which should be checked and avoided.
