NGK Insulators has extended its collaboration with Energous Corporation, a leading developer of RF-based charging for wireless power networks for IoT, and e-peas, maker of highly efficient power source IC technology, to spread the use of Wireless Power Transmission/Transfer (WPT) systems. NGK will support the development of edge device manufacturers and others who work on WPT systems by developing and providing IoT devices that combine its EnerCera® lithium-ion rechargeable battery with technology from Energous and e-peas.

As society shifts toward IoT, power cables and primary batteries (disposable batteries) have been used to power IoT devices. But wiring and the hassle of replacing batteries are a big issue. WPT is attracting attention as a power supply technology that enables the realization and spread of maintenance-free IoT devices. It enables power supply edge devices to be placed where wiring and maintenance presents difficulties.

NGK and Energous initially entered into a partnership in October 2022 to develop solutions that combine Energous’ WattUp technology with NGK’s EnerCera® lithium-ion rechargeable battery to enable maintenance-free IoT devices. Alongside e-peas, the three companies have now developed a temperature and humidity sensor evaluation kit and are also proposing WPT systems aimed at powering tracking devices used in logistics and other IoT applications such as electronic shelf labels. As part of these efforts, an evaluations kit will be provided to support the development of WPT devices.

This kit can be connected to any type of end-devices in need of energy harvesting technology such as sensors or electronic shelf labels. The EnerCera battery that comes with the kit effectively stores a small amount of energy transmitted through WPT and is capable of releasing an amount of energy large enough to power devices despite being ultra-thin and ultra-small, so it can be used in many kinds of applications. The EnerCera battery series comprise ultra-thin, high-heat-resistance, and high-power Lithium-ion rechargeable batteries best suited for IoT devices.

NGK will continue to collaborate with various partners who possess advanced specialties and help to realize an IoT ecosystem by providing its unique ceramic products such as EnerCera.
