Research overview

  By using sound waves, the structure or material properties can be measured.
This information if different from human tactile and visual information.
Marie Tabaru Laboratory focuses on the heterogeneous structures of materials in the world and conducts research to measure and visualize their “acoustic morphology”.
To establish measurement technique, we fabricate ultrasonic devices required for measurement, establish measurement systems, and perform numerical analysis.
We aim to apply this to fields such as medicine, agriculture, musical instruments, and industry, and relate the results of each research to other applications.
We also conduct joint research with other universities, companies, doctors, etc.

Kotsuzumi event

  A Kotsuzumi event was held on Saturday, March 25, 2023.
We welcomed Mr. Yuji Morisawa, an active professional Koko drum player, to perform live and give lessons.
Using cutting-edge technology, we were able to create a real-time image of the form of our arms when playing the kotsuzumi, and we had a variety of experiences such as being able to play the kotsuzumi effectively while watching the form.
