Foam Pressure Mapping with Optimized Electrodesâ€
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsGeneral comment: In the manuscript “Foam Pressure Mapping with Optimized Electrodes”, the authors describe a modular measurement system that uses an ATtiny 1627 microcontroller to measure the pressure at nine electrodes. The nine electrode modules are controlled by an ESP32 microcontroller that aggregates the data and wirelessly transmits the data to a tablet. The modular system is demonstrated with 1008 individual electrodes. The characterization of the electrode combined with the NCPF is provided along with an optimizing of the electrode geometry. Before the recommendation to publication, I have some concerns which are expected to be addressed by the authors.
(1) In Figure 9, the resistance changes with applied pressure under incomplete linear relationship, why it is incomplete linear?
(2) The impedance vs frequency over various frequency ranges, it’s noted that with increasing of frequency, the impedance decrease. What is the intrinsic mechanism, the authors should add in the manuscript.
(3) Several articles on pressure sensing and triboelectric effect are very relevant to this work, which should be referenced in the manuscript including: Advanced Functional Materials, 2018, 28, 1802989; Advanced Functional Materials, 2018, 28, 1805277.

“Before the recommendation to publication, I have some concerns which are expected to be addressed by the authors.”
“In Figure 9, the resistance changes with applied pressure under incomplete linear relationship, why it is incomplete linear?
The impedance vs frequency over various frequency ranges, it’s noted that with increasing of frequency, the impedance decrease. What is the intrinsic mechanism, the authors should add in the manuscript.”
Both of these comments are address by the text that was added after Figure 9 discussing the linearity of the pressure versus impedance.
“Several articles on pressure sensing and triboelectric effect are very relevant to this work, which should be referenced in the manuscript including: Advanced Functional Materials, 2018, 28, 1802989; Advanced Functional Materials, 2018, 28, 1805277.”
Four references were added include those two referenced by the reviewer.
Reviewer 2 Report
Comments and Suggestions for AuthorsNCPF, an affordable foam, measures static loads comfortably using an electrode system. Pressure alters foam impedance, converted to voltage. An ATtiny 1627 captures data from 9 electrodes, managed by an ESP32 for wireless transmission to a tablet. 1008 electrodes show system scalability. Study includes electrode-NCPF analysis and geometry optimization

“What is the primary objective of using optimized electrodes in foam pressure mapping?”
At the beginning of section 2.3 text was added stating the primary objective of optimizing the electrodes.
“How does the optimization of electrodes impact the accuracy and precision of foam pressure mapping?”
In the Discussion section a sentence was added explaining that the strain rate and foam relaxation are more significant to precision and accuracy than the electrode optimization.
“What specific parameters or characteristics are considered when optimizing electrodes for pressure mapping applications?”
At the beginning of section 2.3 text was added stating the specific parameters are the electrode gap and width.
“Can you explain the technological advancements or methods used to optimize electrodes in foam pressure mapping systems?”
The methods used to optimize the electrodes are covered in Section 2.3.
“What are the potential challenges or limitations encountered when implementing optimized electrodes for pressure mapping in foam applications?”
Text was added to the Discussion section describing the challenges of the system.
“How does the quality of electrode optimization affect the overall reliability and durability of pressure mapping systems?”
Information was added to Section 2.3 discussing that the different electrode parameters do not affect the reliability and durability.
“Are there specific industries or fields where foam pressure mapping with optimized electrodes has demonstrated significant advantages or applications?”
Text was added to the end of the manuscript summarizing the demonstrations and describing the places where it could be applied.
“Could you elaborate on the comparative advantages between conventional and optimized electrode systems in foam pressure mapping?”
The optimized electrode is a conventional electrode. So, nothing was changed with respect to this comment.
