Energous Corporation, a developer of RF-based charging for wireless power networks, and Atmosic Technologies, a provider of energy harvesting wireless platforms for the Internet of Things (IoT), unveiled their Wirelessly-Charged Sensor Evaluation Kit that enables battery-free and long-life battery IoT applications through wireless power transfer.

The evaluation kit features Atmosic’s ATM3 energy harvesting Bluetooth Low Energy System-on-Chip (SoC) solution and Energous’ FCC-certified 1W WattUp PowerBridge transmitter.

As members of the AirFuel Alliance, the newly announced evaluation kit further expands the partnership between Atmosic and Energous by showcasing the interoperability in the delivery of an out-of-the-box battery-free sensor solution.

“As the size of the IoT ecosystem continues to rapidly expand, providing these billions of devices with reliable wireless power is critical,” says Cesar Johnston, CEO of Energous. “This evaluation kit will provide our customers with the fundamental building blocks that can be implemented and customized to create WattUp wireless power networks and support the customer specific application needs.”

The IoT ecosystem continues to expand rapidly and is expected to grow from 12 billion devices today to nearly 40 billion by 2025, according to IDC. Billions of these devices are fueled by batteries that require replacement, or are powered by cumbersome charging cables and cords that both present logistical problems and hidden costs to IT teams in any large-scale IoT deployment. The evaluation kit from Atmosic and Energous aims to help solve these challenges with a wireless IoT sensor network solution that never needs a battery replacement.

The kit features two Bluetooth LE radio frequency (RF) harvesting sensor modules which transmit real-time temperature, humidity, and acceleration readings to the Energous WattUp Application while operating from energy harvested at distances of 2 meters from the WattUp transmitter making this solution ideal for applications including industrial IoT, healthcare, and retail operations.

“Together with Energous, we are developing and offering solutions that alleviate the battery maintenance concerns and implementation cost that holds back many of the advanced IoT deployments needed by companies today,” says David Su, CEO of Atmosic Technologies. “The combination of our BLE with power harvesting capabilities and Energous’ FCC-certified 1W transmitter will open up over-the-air wireless power transfer for a variety of our customers’ IoT applications.”

The Wirelessly-Charged Sensor Evaluation Kit will be available for $500 from both Atmosic and Energous in Q2 2022.
