Battery-free wireless sensor tag enables Ambient IoT
Energous has released 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 wireless sensor tag, Energous now provides a complete ambient IoT platform that includes wirelessly powered, battery-free sensors, RF-based energy transmitters, and cloud-based monitoring software. This integrated system delivers uninterrupted, real-time visibility across supply chains, eliminating the need for batteries, manual maintenance, or traditional wired infrastructure.
The e-Sense tag operates using energy harvested from the Energous wireless power network. It features a compact 4×5 cm form factor, is fully encapsulated and waterproof, and is engineered for reuse in high-volume, operationally complex environments.
The wireless sensor tag continuously reports temperature and location data to the Energous cloud platform and is optimised 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 wireless sensor 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 optimisation, and decision-making based on real-time environmental conditions.
The e-Sense wireless sensor tag further realises the company’s vision for end-to-end ambient IoT. 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 is reshaping how the physical world connects,” concluded Burak. “The launch of e-Sense completes our end-to-end system, 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.”
