Ultrasound × Electromagnetics
A timeless new platform for medical and industrial measurement.

A new way to detect hidden deterioration and change.

ASEM (Acoustic Stimulated Electromagnetic Method) visualizes internal electric and magnetic dipoles induced by ultrasound, revealing their unique properties in a new way.Developed from fundamental research at Tokyo University of Agriculture and Technology, this method makes it possible to detect material “deterioration” and “changes” that were previously difficult to measure.

Using a measurement platform built on the ASEM method, we’re working to extend healthy lifespans through advanced medical and healthcare services, while also improving non-destructive testing in industry.

Discover a whole new way to use ultrasound.
