Re: Capacitive touch rookie needs advice on choosing IC for touch buttons.
Hi,
15.3 mm is thick.
and then the active sensor area is restricted to the size of a finger.
Not much capacitance to expect.
to increase the capacitance you may use some condictive material on the finger side.
For test purpose you may use a copper foil and some two side adhesive tape.
For sure the active area on the sensor side should be equal in size.

If you are free to choose optical sensors instead of capacitive, then check how automatic wiper detects rain drops on the front screen.
