المستخلص: |
The use of Micro-Electro Mechanical System (MEMS) concept for manufacturing accelerometers is relatively new technology. However earlier studies suggest that the measured signals by the MEMS accelerometers generally show deviation when compared with the conventional accelerometer. Hence, a simple Finite Element (FE) model of a MEMS accelerometer has been constructed and the modal analysis has been carried out. The cantilever beam mode of finger used in MEMS capacitive type accelerometers observed in the modal analysis highlights the possibility of errors in measurement which is clearly due to non-parallel plates affect. Hence, few modifications in finger design have been suggested to improve the performance of the MEMS accelerometer. The proposed finger shape provided the rigid body motion which is required to give parallel plates during the finger movements and eliminates the nonparallel effect. |
