Since 1998, our VATrans lab. (Vibration and Acoustic Transducers laboratory) has investigated vibration and acoustic related systems. Final targets are systems for applications, and physical modeling is also performed to understand the profound meaning. Engineering innovations can be realized by the system based on understanding of physical meaning. Main topics are transducers based on vibration and acoustics, and nowadays, we extend our research fields to nanotechnology and bio applications. Researching fields are divided into four groups. Vibration/Acoustic field, MEMS/Nanotechnology field, Bio application field, and modeling/analysis field. In each field, our lab members always do our best to be world first class. Join us!
