NGK Insulators and Torex Semiconductor Unveil Solar-Powered EnerCera Charging Module Demo Unit

NGK Insulators, Ltd. and Torex Semiconductor Ltd. have developed a next-generation charging module featuring NGK’s EnerCera batteries and advanced solar cells, including organic thin-film and perovskite types. Unlike conventional solar-powered systems that directly use solar-generated electricity, this module addresses the limitation of minimal power output in weak lighting conditions, such as indoor environments, where energy generation is typically around 100 µW.

The module integrates solar cells, EnerCera batteries, and Torex’s ultra-low-power power management IC to enable efficient energy harvesting from weak light sources. The harvested energy is stored in the EnerCera battery, which then provides sufficient power to operate the system, expanding potential applications. The use of flexible film-type solar cells, EnerCera batteries, and power management ICs results in lightweight, ultra-thin, and bendable modules.

Applications for the module include wearable devices, IoT edge devices, and indoor environmental monitoring systems for offices and factories. The demo unit was exhibited at Sensor Converge 2025, held from June 24 to 26 at the Santa Clara Convention Center in Santa Clara, CA, USA, and at NGK&rsqu...
