Energous 2W PowerBridge transmitter doubles wireless power for IoT devices

Energous 2W PowerBridge wireless power transmitter

Energous has launched the 2W PowerBridge transmitter that doubles the energizing capability of Energous’ 1W transmitter found in WattUp 1W active energy harvesting developer kit, the “Wirelessly powered sensor evaluation kit“, and various deployments in the field. Energous wireless transmitters are used in IoT applications across the supply chain, logistics, retail, industrial and agricultural industries, which benefit from lower maintenance and wiring costs, and the new 2W transmitter will provide better RF coverage and power levels. Energous further explains its 2W PowerBridge helps reduce the need for replaceable batteries and charging cables since it can power IoT devices at a distance in industrial, commercial, and residential settings leading to a reduced need for maintenance or human intervention, enabling a more automated workflow, and the deployment of “Active Energy Wireless Power Networks”. So while there will also be wasted energy with at-a-distance wireless power, it could still make financial sense for […]

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 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 […]

WattUp 1W active energy harvesting developer kit enables at-a-distance wireless charging

WattUp 1W Active Energy Harvesting Transmitter

Two years ago, we noted Energous’ WattUp hearables developer kit that would charge earbuds with the company’s WattUp near-field wireless charging technology. The company has now introduced the WattUP 1W active energy harvesting developer kit capable of charging multiple IoT devices with at-a-distance wireless charging. The kit is said to be “active” because there’s a 6-inch transmitter, let’s call it a power gateway, and several IoT devices that harvest energy from it. Traditional passive solutions will harvest ambient energy from the surrounding environment, and may not deliver enough power, and do so unpredictably. The developer kit comes with the transmitter, plus one or more receiver units, and relies on the following main chips: Transmitter Dialog Semiconductor DA14682 SmartBond Bluetooth 5.0 Cortex-M0 SoC Dialog Semiconductor DA4100 Wireless Power Transmitter SoC Dialog Semiconductor DA3210 1W Power Amplifier A discrete rectifier and a DA2210 WPT rectifier Receiver(s) Dialog Semiconductor DA14531 Cortex-M0+ BLE 5.1 […]

Energous Launches WattUp Hearables Developer Kit with Near-Field Wireless Charging

We previously wrote about Energous WattUp near, mid, and far-field wireless charging while covering SKIIN smart underwears that could be recharged using WattUp near-field wireless technology, but the technology inside can also support future on the desk (mid-field) or in the room (far-field) charging. The company has now introduced the WattUp hearables developer kit that sadly still does not seem to support mid- and far-field charging yet but provides everything to manufacturers to get started with wireless charging for Bluetooth earbuds, smart headphones, and similar gadgets. The kit offers all hardware and software resource to get started with developing wirelessly charged audio devices: Transmitter reference design with power supply, based on Dialog Semi DA14680 Bluetooth LE chip, DA4100 wireless power transmitter, as well as EN3921 and EN3913M front end ICs. Receiver reference design with DA2223 RF to DC receiver and DA14585 Bluetooth LE SoC Mobile app Reference design user guide […]

SKIIN Smart Underwears Support Energous’ WattUp Near, Mid, and Far-Field Wireless Charging

Near-field wireless charging has been around for several years, but for wireless charging to become really disruptive it needs to work at a distance, and Energous has been working on mid and far-field technology with their WattUp transmissive to charge devices respectively on the desk (mid-field) or in the room (far-field). You need to have compatible devices to work with the technology, and wearables are a prime target, but I was expecting fitness trackers or smartwatches to embed the technology at first, but instead one of the first WattUp compatible wearables are smart underwears from SKIIN. The module found in SKIIN underwears and bras have many of the same features as your typical fitness tracker and some extras: Sensors ECG sensors for Heart Rate Monitoring (HRM) Accelerometer and Gyroscope to measure motion & posture BIA (Bioelectrical impedance analysis) to monitor water intake levels and how your sweat affects your hydration, […]
