【Aim】 |
Based on the application of elastic wave and acoustic wave engineering, micro electro mechanical systems (MEMS) are lectured from the principle to modeling. MEMS is getting more and more important technology field in these days. The priceple, analysis method and modeling of electro-acoustic transducers which are very important in this field, are lectured. Opto-acoustical sensing system is lectured also.

Final examination and short problems in each lecture.
|
【Message form the Lecturer】 |
Starting from the basics of elastic vibration/wave phenomenon and piezoelectric transducers, electro mechanical equivalent circuit modeling is lectured. This modeling is effective to understand the quantitative relationshipt of the device operation.
