★We will be exhibiting at Intex Osaka High-Performance Materials Week from May 8th! ★ Demonstration of piezo sensors available! ★

It is a flexible structure with a soft film piezoelectric material! We provide flexible support for finished products such as accelerometers, pressure sensors, and hydrophones!

Our company offers "piezo film sensors" that can be used for monitoring biological signals such as body movement, as well as for monitoring vibrations, shocks, dynamic strain, and dynamic loads. We have successfully developed piezo film sensors into products such as "hydrophones," "ultrasonic probes," "accelerometers," "acoustic pickups," and "pressure sensors." Our expertise, built from years of experience with piezo films, allows us to excel in sensorization of complex shapes and circuit design tailored to the sensors. Our piezo film sensors have a proven track record! They are used in a wide variety of applications, including medical device manufacturers, construction machinery, and automotive manufacturers. They are suitable for monitoring biological signals like body movement, as well as for monitoring vibrations, shocks, dynamic strain, and dynamic loads. *For more details, please download the PDF or feel free to contact us.*

This is a document introducing piezoelectric sensors that are utilized in space exploration and research.

Piezo sensors are used in various applications due to their characteristics, and I would like to introduce one of them, the "space dust sensor." What mission did the piezo sensor embark on into space? What is piezo? What is a piezo sensor? If you are interested, please feel free to download and take a look!

This is a document introducing the flexible sensors handled by Kureha Trading, including their applications.

The flexible sensors we handle have numerous advantages! - High flexibility - Ultra-thin - Ultra-lightweight - No power supply needed - Easily customizable, etc. This is a document that clearly introduces photos and applications of such flexible sensors. Recently, miniaturization and lightweighting of products have become essential challenges... This may help solve those challenges. *If you are interested, please feel free to download and take a look!

"Where is the sound coming from?" --- What kind of speaker do you imagine for the future?

It looks like just a transparent film. This film, which is thinner than paper, becomes a speaker. You can design it freely in various shapes, taking advantage of its high flexibility, such as curving it to any size, allowing for integration with various interiors. The essential food wrap "Kurewrap" is a product developed by the Kureha Group, and the "transparent film speaker" introduced on this page also features a special film with piezoelectric properties developed by the same group. Would you like to experience the future of transparent film speakers, born from the technology cultivated in the development and manufacturing of Kurewrap? If you are interested, please feel free to reach out!

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm. Please feel free to contact us for more information!

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If you require a detailed technical explanation, please contact us.
