Modelling of Resonance Frequency of MEMS Corrugated Diaphragm for Capacitive Acoustic Sensors (TECHNICAL NOTE)
In this paper, a new model for resonance frequency of clamped circular corrugated diaphragm has been presented. First, an analytical analyzes has been carried out to derive mathematic expressions for mechanical sensitivity of diaphragm with residual stress. Next by using Rayleigh's method we present mathematical model to calculate the resonance frequency of corrugated diaphragm and investigate ...
متن کاملCapacitive Touch Sensors
Today, capacitive touch sensors are widely used in consumer products like MP3 players, mobile phones and other portable devices.

متن کاملLoad Carrying Capacity of Simply Supported Variable Thickness Circular Plates
The calculation of the load carrying capacity of variable thickness circular plates subjected to arbitrary rotational symmetric loading is presented. The analysis considers plate materials that obey either the square or the Tresca yield criterion. By using upper and lower bound theorems of limit analysis, corresponding estimations for the load carrying capacity of the plate are obtained. It is ...
متن کاملAnalytical Speedup for the Optimal Design of MEMS Touch Mode Capacitive Pressure Sensors
Obtaining an optimal design for micro electro-mechanical systems (MEMS) structures is a computationally-intensive and time-consuming task as it usually involves numerous non-linear finite-element method (FEM) simulations. This work presents an analytical method to achieve a near-optimal design for circular diaphragm touch mode capacitive pressure sensors and thus find an optimal design without ...
متن کاملModelling and Optimisation of a Spring-Supported Diaphragm Capacitive MEMS Microphone
Audio applications such as mobile communication and hearing aid devices demand a small size but high performance, stable and low cost microphone to reproduce a high quality sound. Capacitive microphone can be designed to fulfill such requirements with some trade-offs between sensitivity, operating frequency range, and noise level mainly due to the effect of device structure dimensions and visco...
