Nanopower and TDK Collaborate on Indoor IoT Detector with Solid State Battery

Nanopower in Sweden has joined forces with TDK to create a groundbreaking wireless indoor IoT sensor demonstrator featuring a cutting-edge solid-state battery. This collaboration marks a significant advancement in the field of IoT technology, offering innovative solutions for indoor sensor applications.

The wireless demonstrator showcases the integration of Nanopower's nPZero power management IC (PMIC) with TDK's indoor PV cell and CeraCharge rechargeable solid-state SMD batteries, along with the nPZero power-saving IC. This combination of advanced components enables efficient energy management and long-lasting performance for indoor IoT sensors.

Designed for Bluetooth Low Energy connectivity, the system is ideal for monitoring temperature and movement within indoor spaces such as windows. Its energy-efficient design allows for seamless installation and operation, utilizing ambient light harvesting stored in ceramic batteries to power the sensors.

The nPZero power-saving IC plays a crucial role in managing the harvested energy and overseeing sensor operations while consuming minimal power in the range of nanoamps. By employing a sub-threshold design, this power management hub effectively controls the wireless chip, processor, sensors, and peripherals of the system, activating them only when necessary. This intelligent approach ensures that essential functions of the IoT device are preserved while enhancing energy efficiency.

Furthermore, the CeraCharge solid-state battery serves as a reliable energy storage solution, complementing the system's film solar cells for indoor photovoltaic power generation. The integration of components such as the LIS2DW12 low-power 3-axis accelerometer from ST Microelectronics and the AS6212 temperature sensor and TSL2540 ambient light sensor from ams further enhances the capabilities of the IoT sensor demonstrator.
