Magnetorheological Fluid-Based Haptic Feedback Damper

Round 1

Reviewer 1 Report

Dear authors thank you for sending this paper to Applied Sciences. The contents are well explained and presented, very appropriate for this journal. English quality is scientifically high and the organization of the contents is appropriate. However, it is suggested to extend the conclusions, explaining any limitations and how the research can be improved or followed by others. 

thank you

Reviewer 2 Report

In this manuscript, the authors have proposed an innovative approach using magneto-rheological fluids to create variable-damping dampers, replacing traditional damping fluids. This approach opens up new perspectives in the field of damper design. However, it is important pointing to the need for further study to assess the durability, reliability and long-term effectiveness of this technology compared with traditional methods. In addition, it might be relevant to further explore the practical implications and possible limitations of using magneto-rheological fluids in real applications.

In the reviewer opinion, the paper can be recommended for publication in Applied science journal after addressing the following comments:

-          Figure 8 and 9 it is recommended to make a comparison with the conventional damping fluid to see the efficiency.

-          Section 4.1 the description of the process parameters in each experiment should be drawn in a table

-          It is recommended to add some results about the damping force with this technology and compare the result with the conventional damping force within the same application

-          What about assessing the durability, reliability and long-term effectiveness of this technology.

-          What are the possible limitation to use magneto-rehological fluids in real applications with bigger scale then keyboard bottons?

Reviewer 3 Report

Page 2. Lines 42-44. Firstly, is it really about the vehicle's comfort, and not the driver and passengers? Secondly, how do the authors know that ride stability will be improved? Have road tests been conducted? If not, please provide a literature source.

Page 2. Lines 44-46. ...and now the authors are bridge specialists? Similar remark, were such studies conducted? Please provide a literature source.

Page 2. Lines 88-89. This sentence repeats information given in the introduction (lines 27-29). What is the purpose?

Page 6. Lines 149-151. It would be worthwhile to write a few sentences about the Comsol program before presenting the results.

Page 8. Figure 12. The figure presents abbreviations and symbols that have not been explained anywhere and may cause difficulty for the reader.

Page 10. Table 1. Since the unit [mm] is presented in the first row, what is the purpose of including it with the values? Percentages [%] were correctly provided.

Page 12. Figures 17 and 18. Why do the abscissa axes lack a title, similar to Figures 9 and 10? What is the purpose of suddenly boldening the font?
