Energy harvesting

■ IoT The growth of the IoT (Internet of Things) market imposes new requirements not only for improving productivity and developing new business models, but also by related devices. Requirements include reliability, accuracy, autonomy, maintenance -free, etc. The protagonist of the IoT is a ubiquitous sensing device that does not depend on the cable connection and can be installed everywhere. For this reason, energy harvesting (environmental power generation), which uses environmental and wireless information communication using environmental energy, is important. ■ Energy Harvesting with Wee Gand effect Environmental power generation technology varies, and each has its own characteristics. The main approach to energy harvesting, such as solar power generation, thermoelectric power generation, and RF harvesting, depends on whether each energy form is available in the environment. Induced Energy Harvesta is a method that uses kinetic energy. The drawback of induced energy Harvesta is that the energy level available at very low exercise speed is low. Energy Harvesting with the Wewigand effect has overcome the tasks at low speeds, taking advantage of the guide -type energy harvesting without relying on machine parts. ■ UWB (Ultra Wide Band) Wireless technology The accuracy of the Time of Flight measurement method and the coexistence of the narrow band wireless technology achieve surprisingly low energy consumption. UWB has already succeeded in many applications. In UWB, transmitting power is not always a power supply frequency generator, but is consumed only by short pulse, so it is an excellent candidate for wireless transmission technology adopted in wireless sensor nodes supplied by energy harvesting from Weaegand Generator. It is.
