Wirelessly powered sensor evaluation kit comes 1W power transmitter, two battery-free sensors

Energous WattUp wireless power technology delivers power at various ranges (up to a few meters), and so far, we’ve seen it in wearables like garments, as well as smart glasses and earbuds development kits.

The company has now launched a wirelessly powered sensor evaluation kit for the Internet-of-Things (IoT) based on the 1W WattUp PowerBridge transmitter with Bluetooth LE 5.0, plus two battery-free sensor nodes based on Atmosic ATM3202 Bluetooth LE 5.0 Cortex-M0 microcontroller with energy-harvesting capabilities.

Wirelessly powered sensor evaluation kit

Wirelessly powered sensor evaluation kit content & features:

  • 1W WattUp PowerBridge transmitter
    • Bluetooth LE microcontroller
    • Energous EN4100 transmitter IC
    • Energous EN3210 power amplifier
  • 2x Atmosic battery-free sensors
    • MCU – Atmosic ATM3202 Cortex-M0 microcontroller @ 16 MHz with integrated RF energy-harvesting using MPPT (maximum power point tracking) algorithm to maximize harvesting performance
    • Sensors – Temperature & humidity sensor, 3-axis accelerator
    • Power consumption – A 1/4th of the power consumption of a typical BLE beacon

Energous WattUp PowerBridge, Atmosic RF-Energy harvesting devicesThe companies also offer a mobile application to get the sensor data over Bluetooth LE.

Just like the previous Energous devkits, the Wirelessly powered sensor evaluation kit is designed for companies that are looking at taking wireless charging to mass production, and you’d need to sign an NDA first to discuss potential applications with power and other requirements. More details may be found on the product page and press release.

Technologically speaking it’s awesome. But the more we’re saying “we need to reduce our power usage”, the more we’re seeing wireless devices that waste 99.9% of their energy heating the air around… It seems that marketing and people’s laziness will always win.
