Toyoda Gosei and Ball Wave will leverage Toyoda Gosei’s surface treatment technologies, such as painting and plating technology cultivated in the development and production of automotive interiors and exteriors, to achieve coatings for better ball SAW sensor performance. In the future, the two companies aim to develop a sensor that can detect viruses in the air with a view to combining it with Toyoda Gosei’s deep UV LED technology that can eliminate the novel coronavirus and other viruses.

Toyoda Gosei will continue to tackle social issues through collaboration with startups that are promising for synergy with its core technologies.


100 million yen was invested in November 2020.


Ball Wave has commercialized devices such as a high-performance trace moisture sensor that can be used in semiconductor manufacturing processes and drying rooms.
