I asked this question yesterday and only got one answer, from someone whos answer was "I don't know"?
How or what does the finger tip mouse pad on a laptop read? We already know that it responds to the naked fingertip, that is given.
BUT, if you put a very very thin knit cotton glove on, it does not respond at all. If you use a piece of silver, it does not respond at all. BUT, if you use a piece of real gold, it responds just as it does with your finger tip. What does gold and a finger tip have in common and how does this thing work?

The link below describes how the touchpad on your laptop works.
Since it responds to the capacitance of human skin.. then gold must be very close to that.

They are, as Equinox said, electrical. The touchpad contains sensors that sense the capacitance of your finger--apparently, your skin acts as a capacitor. This explains the very very thin knit cotton glove effect: I highly doubt cotton conducts electricity very much at all. Gold, however, conducts it very well, as Equinox said.
By the way, answers like "I don't know" that aren't actually answers at all can be reported using the little flag icon: just click it, select "not a question or answer", and type in some sort of summary.

Idea not sure: It either responds to heat. Or maybe to electicity from your finger? Gold conducts electricity very well.

To be honest they are different types but in general the pad picks up the heat from the fingers

perhaps it is reading electricity as the human body has naturally electricity running through it and gold is a very good conductor while silver is ok but not as a good as the human body or gold
Cotton is no good at conducting electricity either so this lines up with your observations...
Those are my thoughts

I think have a sensor like you press any key , but the sensor of pad is in range of time you keep press.
somo are touch sensitve but other are you need to keep the pad then you move where u choose to move the pointer.

Instead of complaing try using a search engine:

When I was learning about computers we didn't have search engines or the Internet.
