Energous Corporation (Nasdaq: WATT), a leading developer of RF-based charging for wireless power networks, and Atmosic Technologies, an innovator in energy harvesting wireless System-on-Chips (SoCs) and modules for the Internet of Things (IoT), today announced they are taking orders for the Wirelessly Powered Sensor Evaluation Kit, which features Atmosic’s ATM3 energy harvesting Bluetooth Low Energy (BLE) SoC solution and Energous’ FCC-certified 1W WattUp PowerBridge transmitter. Kits will begin shipping later in July.
The Wirelessly Powered Sensor Evaluation Kit highlights the unique capabilities of wireless power through an out-of-the-box battery-free sensor solution and provides IoT device developers with the ability to explore how wireless power transfer can support devices such as sensors and tags, ultimately enabling IoT deployments that are not reliant upon replaceable batteries or power cables but are instead powered wirelessly over-the-air.
“Without reliable power, IoT devices in any application are significantly limited in their capabilities and value, and the billions of replaceable batteries and charging wires powering most of today’s internet-connected devices fail to meet their growing power requirements,” said Cesar Johnston, CEO of Energous. “Along with Atmosic, we’re thrilled to announce the availability of our evaluation kit, which gives IoT device developers a low-cost solution to reduce device dependency on unreliable power sources and reliably power billions of IoT devices wirelessly.”
The number of IoT devices is projected by IDC to more than triple over the next three years, growing from about 12 billion devices today to almost 40 billion by 2025. All these devices require consistent and reliable levels of power to function properly, however, most are currently fueled by replaceable batteries – which are impacted by variables including temperature and frequency of use – or by the cumbersome power cables and cords that bring with them logistical problems and additional hidden costs to IT teams and their budgets.
The Wirelessly Powered Sensor Evaluation Kit from Energous and Atmosic is designed to help alleviate many of the most pressing challenges with the large-scale wireless IoT sensor deployments by removing the need for batteries or power cables and the long-term maintenance overhead required to maintain them in busy commercial, retail, and industrial environments. The kit features two Bluetooth LE radio frequency (RF) harvesting sensor modules that transmit real-time temperature, humidity, and acceleration readings to the Energous WattUp Application while operating from energy harvested from the WattUp transmitter, making this solution ideal for applications including retail operations and industrial IoT.
“Advanced IoT deployments are too often stunted due to concerns around implementation costs and battery maintenance, two challenges that now have a clear solution and are addressed through our evaluation kit with Energous,” said Srinivas Parramatta, VP Marketing and Business Development of Atmosic Technologies. “Energous’ FCC-certified 1W transmitter combined with our BLE power harvesting capabilities now make over-the-air wireless power transfer possible for many IoT applications, such as electronic shelf labels, access control or IoT sensor beacons.”
The Wirelessly Powered Sensor Evaluation Kit includes one (1) Energous 1W WattUp transmitter, two (2) Atmosic energy harvesting sensor modules, and a mobile application for sensor monitoring and transmitter control.
