Sumitomo and Kansai University develop technology to generate power from static electricity in tires

Sumitomo and Professor Hiroshi Tani of Kansai University have developed a new technology to generate electricity from the rotation of a tire. By installing a power generating device (or Energy Harvester) inside a tire, researchers were able to convert static electricity into clean energy. The new device, which Sumitomo calls the ‘SMART TYRE CONCEPT’, takes… Read more »

Sumitomo Electric’s new generation of SiC transistors offer low on-state resistance

Sumitomo Electric’s new V-groove superjunction transistors, which it developed through a joint research project with the National Institute of Advanced Industrial Science and Technology (AIST) use silicon carbide (SiC) semiconductors, and the company claims they offer the lowest on-state resistance yet achieved in an SiC transistor. Sumitomo has already developed V-groove MOSFETs that use a… Read more »
