Model for surface touch panel

I'd like to create a model for the touch panel which basically is a capacitor net ... By clicking on this panel you are changing the capacitance of the respective circuit (row, column)...

How to create a "click (touch mimic)" sensitive virtual surface with Matlab/Simulink?

Hello Peter,

you woudl want to start with the building block variable capacitor: https://www.mathworks.com/help/physmod/sps/ref/variablecapacitor.html?searchHighlight=variable%20capacitor&s_tid=srchtitle_variable%20capacitor_3

You'll need some simscape basics to go along with it: https://www.mathworks.com/learn/tutorials/simscape-onramp.html

Then you need to create a simulink model that controls the capacitance based on where the user is touching, and connect that up to the variable capcitors to control their capacitance.
