MODELLING OF SIMPLY SUPPORTED CIRCULAR DIAPHRAGM FOR TOUCH MODE CAPACITIVE SENSORS
This paper describes the power series solution for modelling of the simply supported circular
diaphragm deflection under uniform load. The parameters such as touch point pressure and
touch radius are defined. Moreover, these parameters are also computed by the algorithm
proposed in the paper. Therefore, the power series solution can be applied for touch mode
operation.
