I'm having trouble understanding how the gas sensor with MOS technology works. I cannot find a study material with the basic principles of operation. I can find some subjects, but with information such as too deep knowledge, I have no in-depth knowledge on the subject. Could someone please explain give me a link, document (PDF) that talks about this subject in a fundamental way how it works?

It is difficult to answer my questions, because I do not speak English, so there may be a failure in communication. I'm trying my best to translate for you. I will try one more time. I don't know how a cantilever gas sensor with MOS technology works. How do the two work together?

NOTE:
you offend me. I know how to use Google, but this kind of information is hard to find.

find it funny that only on this platform I am harassed.

 

will tell you what I understand. when we have the resonant cavities in the case of this cantilever device, when there is a molecule on the surface of this device, it will respond at a certain frequency. That way we will know what substance is on the surface of the device. Because it will vibrate at that frequency x. My problem is: I cannot understand this relationship with the mosfet when we deal with gas sensors, I cannot understand the basic principle associated with the mosfet device (attention I know how the mosfet works). I can't find a simple relationship about understanding (explanation of the subject).

 

you offend me. I know how to use Google, but this kind of information is hard to find.

No offense meant. You asked for PDF's on them and Google gave them to me. Sorry they don't meet your standards.

 

This article explains what the mosfet does: https://www.degruyter.com/view/journals/revac/32/2/article-p135.xml Search on "mosfet" in the text. The description is just above Figure 4. Basically, a mosfet is incorporated into the base of the cantilever such that flexion changes the relationship of the gate/source/and drain. Thus, conduction by the mosfet changes.
