Energous introduces battery-free e-Sense tag, establishing first end-to-end wireless power platform for the Ambient IoT

Energous Corporation d/b/a Energous Wireless Power Solutions (NASDAQ: WATT), a leader in over-the-air (OTA) wireless power networks, today announced the launch of the e-Sense tag, a battery-free, maintenance-free wireless sensor for location and temperature monitoring in retail, supply chain, and logistics environments.
With the introduction of the e-Sense tag, Energous now offers a complete ambient IoT platform consisting of wirelessly-powered, battery-free sensors, RF-based energy transmitters, and cloud-based monitoring software. This integrated system enables uninterrupted, real-time visibility across supply chains without relying on batteries, manual maintenance, or conventional wired infrastructure.
The e-Sense tag operates using energy harvested from Energous’ wireless power network. It features a compact 4x5 cm form factor; is fully encapsulated and waterproof; and is engineered for reuse in high-volume, operationally-complex environments.
The tag continuously reports temperature and location data to Energous’ cloud platform and is optimized for retail, transportation, and cold chain applications. It is exclusively compatible with Energous PowerBridge^® transmitters and offers cost-saving benefits compared to conventional battery-powered alternatives.
“Adding e-Sense to our product portfolio positions Energous as a full-stack provider of wirelessly powered sensing and infrastructure solutions for tracking interconnected devices in the ambient IoT ecosystem,” said Mallorie Burak, CEO and CFO of Energous. “This tag eliminates both the maintenance burden and environmental impact of batteries while providing enterprise-grade sensing and connectivity at scale – enabling businesses to bring intelligence to products, pallets, and packages in their supply chains at scale.”
Sensor data from the e-Sense tag is transmitted to e-Compass, the company’s secure, cloud-based asset intelligence platform. The platform offers real-time monitoring, device management, zoning, reporting, and support for historical data analysis. Built on AWS IoT Core, e-Compass supports enterprise deployments with tools for regulatory compliance, process optimization, and decision-making based on real-time environmental conditions.
The e-Sense tag further realizes the company’s vision for an end-to-end ambient IoT solution. Together with Energous transmitters and e-Compass cloud software, it forms a system architecture that delivers persistent visibility, energy autonomy, and operational efficiency across large, distributed supply chains.
Ambient IoT enables a new class of connected devices that are smaller, lower-cost, and more sustainable than traditional, battery-powered sensor technologies. As global enterprises scale deployments to improve traceability, compliance, and automation, wireless power is becoming an essential layer of infrastructure. Energous provides the certified technology, deployment experience, and platform integration required to support these initiatives.
“Ambient IoT is reshaping how the physical world connects,” concluded Burak. “The launch of e-Sense completes our end-to-end solution – bringing together wireless power, intelligent sensing, and cloud-based visibility into a single, scalable platform. It reflects our continued commitment to delivering the wireless, battery-less infrastructure required to support the real-time supply chain visibility that will transform industries.”
