Tohoku University in Japan announced on November 24th, 2016 that it has established a technology for implanting mechanical structures by improving the “magnetostrictive effect†of magnetostrictive fibers, and has developed a strong, lightweight and high power generation performance. Composite new material. The material can be used in microenvironment generation and storage functions in the fields of high-sensitivity sensors, wearable devices, and IoT devices, and is attracting attention as a "self-excited power generation type" smart material invented by Japan.
The magnetostrictive material implanted this time is an Fe-Co (iron-cobalt) alloy. The alloy is made into a wire having a diameter of 1 to 0.2 mm so as to exert the property that the magnetic flux easily penetrates into the fiber direction, and also the manufacturing process at the time of implanting the epoxy resin base material resin inside is improved, thereby manufacturing a reverse magnetic flux. Highly elastic composites. In addition, by configuring the coil outside the resin, a large voltage is successfully generated under the impact load. By using this feature, it can be used in stress sensors, damage detection sensors, vibration and impact power generation devices. Although it is a sensor, it has a power generation function, so it is expected to contribute to the development of self-excited IoT sensors.
Fe-Co alloys for magnetostrictive materials have the features of cheap iron-based materials, excellent processability and strength, and excellent magnetization and magnetostriction properties. The alloy was invented in 2011 and mass produced by Northeast Special Steel. The composite functional new material using this alloy realizes the toughness and lightness of two magnetostrictive materials (a rare earth Terfenol-d alloy and a Fe-Ga Galfenol alloy) that were originally made of a rare metal and are fragile and difficult to process. Change. In addition, it can be integrally molded with the structure, so the design freedom is also high.
Some of the research conducted this time was supported by the “Missing Magnetostrictive and Electromagnetic Smart Device Development Research Conference†of the Project Creation Research Association launched by the Miyagi Industrial Promotion Agency. Some of the research results have been published in the electronic version of Advanced Engineering Materials, an academic magazine in the field of materials science. In addition, these results will be presented at the business matchmaking fair and the "Metropolitan Cooperation Exhibition 2016 Miyagi" held at Sendai International Center on November 29, 2016.

Island Light is a type of Pendant Light commonly used over the central island in a kitchen or over a long table in a dining room. It typically has multiple bulbs to provide sufficient light to illuminate the entire area. Island Lights come in a wide variety of designs, ranging from traditional pendant styles to modern, industrial, or artistic designs. Island Lights not only provide light but can also serve as a decorative element in a room.
