講義概要
弾性体の振動・波動を応用した微小なアクチュエータやセンサなどのマイクロシステムに関して，動作原理やそこで用いられる材料，加工・製作技術，モデル化の手法などを修得する。具体的なセンサやアクチュエータを取り上げ，その原理からモデル化を行い理解を深める。
Micro actuators and sensors based on elastic vibration and/or elastic wave are lectured. Starting from materials and fabrication technologies for MEMS (micro electro mechanical systems) devices, structures and principles of the transducers are introduced. A couple of sensors and actuators are studied in detail to obtain clear understanding for actual devices. For this purpose, modeling methods of the piezoelectric electro mechanical system and opto mechatro system are discussed.
講義の目的
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.
