Tamura Corporation’s piezoelectric ultrasound transducers

What are the benefits of your technology over other companies?
We at Tamura pride ourselves on various products, especially our piezoelectric ultrasound transducers. Our ceramics offer many beneficial features, such as high strength, wide amplitude characteristic, fit for fine processing, and a low aging rate. Applications for these ceramics include piezoelectric transformers, ultrasonic transducers, fish finder equipment, ultrasonic probes, and various types of sensors.

What distinguishes your company from others?
The biggest factor that distinguishes our technology over others is the fact that during our 100-year history, all ceramic material has been developed and produced in-house. Our high quality, made-in-Japan ceramics are produced to the highest degree with a margin error of less than 1 μm. We set such high standards so that we have the upper hand in terms of durability, reliability, efficiency, and overall quality compared to our competitors.

We have the full confidence that our products can withstand any high-powered uses (such as focused ultrasound). Our production line is also equipped with the newest robot technology, so we pride ourselves on our extremely reliable manufacturing processes.

Have your products been used for focused ultrasound research?
Yes, last year we began providing prototypes for focused ultrasound research.

What kind of customers and additional partnerships are you looking for?
We are interested in collaborating with partners who can take our products and materials to the next level and help the many causes in society. Our goal is to bridge the gap between possible and impossible, and we want clients that can help make these dreams a reality.
