Energous Corporation announced the availability of its 5.5W Active Energy Harvesting Developer Kit, to enable at-a-distance wireless charging for the industrial Internet of Things (IIoT) and other connected devices.

Unlike passive solutions that harvest ambient energy from the surrounding environment, which typically offer low amounts of power and can be unpredictable in terms of how much power is available, Energous’ active energy harvesting solution includes a dedicated transmitter that emits 5.5W of conducted power in a specific area or direction via its RF-based, WattUp wireless charging technology. This RF-based energy is harvested by Energous-enabled receiving devices, which can be combined with RF energy harvesting IC technology from e-peas.

The Energous 5.5W active energy harvesting solution supports “one to many” charging, allowing multiple devices to be simultaneously charged from a single transmitter. Energous active energy harvesting technology is applicable to a range of industries and applications, from drug storage monitors and patient trackers in a healthcare setting, to smoke detectors and motion sensors in a smart home, to fault prevention and other safety sensors in an industrial environment.

The 5.5W WattUp Active Energy Harvesting Developer Kit includes e-peas’ power management IC technology with an array of Energous’ IP including:

  • DA4100 highly integrated system-on-chip (SoC) wireless power transfer (WPT) transmitter IC
  • EN3921 Power Amplifier Controller
  • EN3913 High-Efficiency, GaN, Power Amplifier Module
  • e-peas’ AEM30940 RF energy harvesting IC solution

Energous WattUp technology provides an array of over-the-air and at-contact wireless charging 2.0 solutions.
