SoftBank Opens Wireless Power Transfer Lab, Inviting Ideas for Powering IoT Devices with Radio Waves

SoftBank has launched a "Wireless Power Transfer Lab" that demonstrates technology for wirelessly powering devices using radio waves over a distance. The lab is being opened to the public in 2024 to solicit ideas and foster open innovation around this technology. 

The spatial transmission method used sends radio waves (microwaves) like a mobile base station to power devices within the range of the waves. It can integrate with mobile base stations to charge devices nearby wirelessly.

The initial target is IoT devices like sensors, which are expected to proliferate with AI and digital twins. Wirelessly powering these devices eliminates the need for batteries and associated replacement/charging costs.

At the lab, visitors can try the technology using the approved 920MHz band. Demonstrations show existing button battery-powered devices like temperature sensors and Apple's AirTag working without batteries by receiving power from the radio wave transmissions.

While currently limited to around 1mW power for simple devices, SoftBank sees opportunities to enable higher power capabilities in the future through advanced beamforming to avoid the human body. The key advantage over solar is not being affected by environmental conditions.

AIST Develops Highly Elastic and Durable Silicone Polymer for Vibration-Absorbing Adhesives

The National Institute of Advanced Industrial Science and Technology (AIST) has developed a modified silicone polymer with enhanced elasticity and durability through joint research with AGC. This new material can be used as a raw material to produce elastic adhesives capable of absorbing vibration energy and withstanding stretching fatigue.

The key innovation lies in using a catalyst mixture of a carboxylic acid compound with carbon-carbon unsaturated bonds and an industrial platinum catalyst for the silylation reaction. This increases the terminal silylation rate of the polyoxyalkylene polymer to over 95% while reducing the required catalyst amount to just 5 ppm of the raw material.

Tensile testing showed the cured modified silicone polymer exhibited 30% improved modulus performance at 50% elongation compared to conventional products. This enables the adhesive to maintain its shape even under strong vibrations, contributing to higher functionality and durability.

The main applications targeted are adhesives and sealants for construction and vehicle materials. AGC has begun sample work and aims to establish mass production technology to commercialize the product within a few years, leveraging the vibration-absorbing and fatigue-resistant properties of this newly developed silicone polymer.

Zeon and Romero Britto Unveil World's First Artworks with Counterfeit-Preventing Material

Zeon Corporation, in collaboration with world-renowned pop artist Romero Britto, has unveiled the world's first artworks incorporating Zeon's unique new material that prevents counterfeiting. Five of Britto's works, incorporating the innovative "broadband cholesteric liquid crystal material," were revealed at his solo exhibition "Be happy!" in Japan.

The new material exhibits visually striking effects, appearing visible or invisible when viewed through polarized glasses, and displaying different patterns on the front and back sides by reflecting light in specific ways. Crucially, it enables viewers to verify the authenticity of the artwork, addressing the issue of counterfeiting.

Britto expressed enthusiasm for integrating this new technology into his art, stating that it provides collectors with peace of mind by allowing easy distinction between genuine and counterfeit works, even after the artist's lifetime. He highlighted the material's potential for application in sculptures and curved surfaces in addition to flat artworks.

Zeon's Executive Officer Masao Akasaka emphasized the honor of having their new material featured in Britto's works, fusing art and chemical materials to create an unprecedented expression method. He hopes the exhibition will raise awareness about the material's ability to prevent counterfeiting and unlock new value through innovative applications.

Both Zeon and Britto underscored the importance of authenticating artworks and highlighted the new material's innovative solution, enabling artists to deliver genuine pieces and collectors to enjoy artworks with confidence in their authenticity.

AI Enhances Low-Dose CT Image Quality, Enabling Significant Radiation Exposure Reduction

Researchers from Hosei University and Juntendo University have demonstrated the effectiveness of using artificial intelligence (AI) to improve image quality in sparse projection computed tomography (CT), a technique that reduces the number of projection data used to create CT images, thereby significantly lowering radiation exposure.

Key highlights:

1. CT examinations account for the majority of medical radiation exposure, necessitating dose reduction techniques.

2. Sparse projection CT can substantially decrease radiation dose by reducing the amount of projection data captured, but this introduces significant artifacts (distortions) that degrade image quality and diagnostic accuracy.

3. The researchers used AI to correct these artifacts in sparse projection CT images, created through a unique simulation, and evaluated the performance of three AI learning models: autoencoder (AE), U-net, and conditional generative adversarial networks (CGAN).

4. While all three models reduced artifacts, CGAN proved most effective in improving CT image quality while preserving minute structures like blood vessels and bones, albeit with some deformation.

5. The study demonstrates the potential of AI to enhance low-dose CT image quality, paving the way for significant radiation exposure reduction during CT examinations.

6. Future work involves testing the approach on cone beam CT systems, like those used in radiation therapy, which can acquire sparse projection data, bringing the technology closer to clinical application.

“RiceResin": The Biomass Plastic Made from Rice, Reviving Agriculture

Biomass Resin Holdings has developed "RiceResin," an innovative biomaterial derived from rice, addressing the issue of abandoned farmlands in Japan while promoting sustainable agriculture. With a decline in domestic rice production, the area of abandoned farmland has expanded to nearly twice the size of Tokyo, posing a serious challenge.

"RiceResin" offers a solution by utilizing non-edible rice as a raw material for producing biomass plastic. The company's primary goal is to support the agricultural community by providing an alternative income stream through rice cultivation on abandoned lands.

Executive Officer Shinji Okuda emphasizes their commitment to reviving the industry, particularly in areas like Namie Town, Fukushima Prefecture, which was devastated by the Great East Japan Earthquake. Since 2019, they have been expanding their rice cultivation efforts, aiming to reach 10,000 hectares of cultivated land by 2025, using the harvested rice as the raw material for "RiceResin."

"RiceResin" has already found commercial applications, with Daiso selling measuring spoons, rice scoops, and measuring cups made from the material for 110 yen each. Additionally, an afternoon tea brand has launched a lunch box containing 10% "RiceResin," and Shimizu Shoji has introduced the "Howari" series of tableware made from the material.

Furthermore, Biomass Resin Holdings is developing "Neoryza," a biodegradable plastic derived from rice. Scheduled for launch in Japan in 2025, "Neoryza" is being tested for use in garbage bags and agricultural materials. By using "Neoryza" for mulch films in fields, the need for stripping and disposing of the films after use is eliminated, reducing processing costs. Sanyo Chemical is also working on a biodegradable fertilizer coating using "Neoryza" to address the issue of fertilizer coating being washed away and polluting rivers and oceans.

Through the development of "RiceResin" and "Neoryza," Biomass Resin Holdings aims to revive the agricultural industry, promote sustainable practices, and create value from non-edible rice, demonstrating the potential of biomaterials in addressing environmental and economic challenges.
