Round 1
Reviewer 1 Report
There are no MAIN questions opened because the proposed work is, in my opinion, complete and solid. For a better understanding of the material, I would suggest the Authors address these MINOR points:
A. Fig. 19: which is the physical reason of the non monotonic shape of the curve of the resistance vs. time? The Authors are invited to add a brief comment in the text.
B. Which is the impact of the mechanical/manufacturing tolerances on the performances of the sensor ? The Authors are invited to add a brief comment in the text.

Reviewer 2 Report
I recommend outright rejection of the manuscript.
It’s contents can be summarized as follows:
A microsensor of unclear nature, in a bulky housing (“dimensions are length 90 mm, the diameter is 30 mm, and the front end is placed in a pipeline of about 25mm”) was placed in unclear location of unclear test cell of vanadium redox flow battery. Testing of the sensor in the test cell and in Environmental Chamber gave reasonable results.
To protect the sensor from the aggressive environment of the vanadium redox flow battery “a layer of protective glue (Epoxy) is first applied to the shell of the micro-sensor, and then soaked in epoxy resin to make it withstand voltage and resistance, grinding, acid and alkali resistance, seamless, beautiful, easy to clean and other advantages”.
These three quoted lines of text is the only link of the manuscript to the subject of the Journal.
It is absolutely unclear by what way this bulky microsensor was placed in a very tight inner space of the vanadium redox flow battery.
The manuscript is written in primitive English.

Reviewer 3 Report
The authors present an insightful work on Flexible micro-sensor packaging and durability for real-time monitoring of vanadium flow batteries. The manuscript is present in well-arranged data order and written very well.
-Keywords: Mostly from the title and looks lengthy, need to be revised.
- data-driven methods from the statistics and data probability are generally complex. How the authors deal with it?
-The authors need to cite with novel study along with “https://doi.org/10.1002/bkcs.11380”
- Abstract: The authors need to better present and quantify the performance of the MEMS technology model in their abstract.
-Table 1: Is this done through some sensitivity study or hyperparameter optimization?
-Are there any bounds on the input training data? How will the model perform if unseen data is used – for example extreme temperature or load conditions?
