Round 1

Reviewer 1 Report

In Table 1 could also be useful to indicate the thickness of the sensors.

 

Line 155: Then, a flat die applies a 155 forming load to the exposed surface of the copper wire.

What is the equipment used to apply that load?

 

The ceramic insulator (Al2O3) is also manufactured by a parting-off grinding process.

Any details about that process? To process the Al2O3 is a complicate task…

 

It will be interesting to know more details about the simulation model in ANSYS.

 

A signal-noise ratio in Table 4 could be interesting.

 

As a general comment, Is there another way to measure the signal displacement than using a vibrometer?. A low-cost circuit, where the frequency output is measure, could be interesting thinking in a final application of the sensor.
