Round 1

Reviewer 1 Report

I have read the article with great interest, nevertheless several issues must be figured out before accepting the manuscript:

-      I would be happy to see in the article some figure from experiments. The graphical schemas are not sufficient to my opinion.

-      I would suppose not use the term “pressure” in the text, but force in your case, because you use Newton unit.

-      It is not clear what “E” means. Perhaps young´s modulus? It must be indicated in the text.

 

-      It is not clear how the finite element model was build up. The type of material model, elements, boundary conditions and so on.

Reviewer 2 Report

Zhao and their coauthors reported a bifunctional sensor that can detect different modes of touch. Their artificial receptor is composed of double ionic layers separated by PDMS elastomers, and they claimed the sensing mechanism is based on the ion-electrical effect so their device can work as a self-powered tactile sensor, which the reviewer feels novel and interesting. The current manuscript is well-written and their experiments are scientifically sound. Therefore, the reviewer suggests their acceptance before they can address the following minor issues.

(1)   Considering the experiment setup, it is similar to the measurement of triboelectricity. So the reviewer wonders if the working mechanism might have something to do with the triboelectricity. How can the authors prove the generated voltages are not coming from the contribution of static charges? Please clarify or provides further evidence. If the working mechanism belongs to the ion-electrical effect, then the reviewer believes the temperature will have a significant effect (determining the mobility of ions) on the performance of the device.

 

(2)   For Fig 7c, 7f, and 8b, error bars are required.

 

(3)   Page 1, Line 25, “3mm to 1mm” should be “3 mm to 1 mm”
