This is a sheet-type electromagnetic wave absorber that can be used for noise countermeasures in millimeter-wave radar, millimeter-wave sensing, information communication devices (Beyond 5G), and more. Unlike conventional products that absorb only specific frequencies, this sheet can absorb a wide range of millimeter waves extending to several tens of GHz, allowing it to accommodate multiple devices with different frequencies using just one sheet. The design of the sheet also allows for adjustment of the absorption frequency to the desired band. It is lightweight and flexible, making it possible to process into any shape, and can be attached to various locations by providing an adhesive layer.

Dielectric elastomers are flexible polymer materials that deform under voltage. Our company laminates conductive elastomers with dielectric elastomers, allowing them to be used as is without the need for applying carbon grease. We are exploring a wide range of applications that leverage the deformation characteristics due to electrostatic forces. Furthermore, we are also considering applications for power generation using dielectric elastomers.

Once rich, the seagrass beds are decreasing year by year due to environmental changes and human impact. Seagrass beds serve as habitats for marine life and also play a role as "blue carbon" by absorbing and sequestering CO₂. Now, the restoration of seagrass beds is urgently needed for both ecosystem conservation and climate change mitigation. To tackle this challenge, we are developing a sheet that enables the easy construction of seagrass beds.

We have developed a transparent and highly flexible film that contributes to reducing environmental impact through high biomass content and biodegradability. This film is modified polylactic acid (PLA) using our unique technology, maintaining transparency while achieving both flexibility and heat resistance. Additionally, its softness and excellent moldability help suppress whitening during folding processes. 【Features】 ■ Provides flexibility to normally rigid polylactic acid (PLA) ■ Contributes to reducing environmental impact with over 95% high biomass content and biodegradability ■ Can be utilized for packaging that takes advantage of visibility ■ Improves heat resistance from around 60°C to over 100°C *For more details, please download the PDF or contact us directly.
