Popis: This article describes the power series solution to the model of circular diaphragm deflection under uniform load. The parameters for touch mode operation, such as touch point pressure and touch radius, are defined and computed by the algorithm proposed in this article. Therefore, the power series solution can be applied for touch mode operation. Based on the analysis, a spreadsheet solution software is programmed as a tool for touch mode capacitive sensor design and performance estimation. Compared the results from this tool and ABAQUS simulation, the error is within 5% and this PC-based tool is very promising in time saving.
