"Conventional brain surface-attached sensors struggled with this because the ultrasound-induced vibrations caused significant noise, making it difficult to monitor brain waves in real-time," said Son.

Toppan has developed a product that allows users to control the reflection angle of radio waves in the 1–10 mm wavelength band used in 5G mobile communications. The product is a lightweight, flexible ...
