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 […]

Panthronics PTX30W is a 1W NFC wireless charging listener IC

Panthronics PTX30W is an NFC wireless charging listener chip that can receive up to 1W as per the NFC Wireless Charging (WLC) specification unveiled in 2020 and integrates a power management unit and a Li-Ion battery charger. Offered in a compact 3.2mm2 (1.78 x 1.78 mm) WL-CSP package, the PTX30W will enable small battery-powered products, such as smartwatches and other wearables, to be charged over NFC. The chip can operate in standalone mode or connected to a host microcontroller, and the company claims it is around four times smaller than existing designs based on multiple discrete components. PTX30W features and specifications: Integrated NFC Wireless Charging Listener device Efficient Active Rectifier RF interface according to Forum Type 2 Tag Li-Ion battery charger with charging current from 5mA to 250mA MCU LDO with 1.8V or 3.3V output, up to 50mA Embedded power negotiation logic High-efficiency NFC wireless charging listener IC with up […]

Craob X – An ultrathin, portless laptop with a wireless charger & dock

They’ve already taken out our audio jacks, and many laptops don’t come with an Ethernet port, but the Craob X portless laptop goes even further by completely removing all ports, and relies on a magnetic wireless charger that sticks to the laptop lid, and offers some USB and audio ports, you know just in case you actually need to connect wired peripherals… The main advantage is that you’d get an ultra-thin 7mm thick laptop that only weighs around 860 grams. As long as you mostly rely on wireless keyboards, mice, headphones, or storage devices that may be a working solution, and if you need to charge the battery simply place the wireless charger on the back of the display. Craob X portless laptop preliminary specifications: SoC – Up to Intel Core i7-1280P Alder Lake processor with Iris Xe graphics (28W TDP) System Memory – Up to 32GB LPDDR5 RAM Storage […]

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 […]

NuCurrent showcases NFC charging at 3W, data rates up to 848 kb/s

The NFC Forum approved the Global Wireless Charging (WLC) specification last year with the new standard making it possible to wirelessly charge small, battery-powered consumer and IoT devices with a smartphone or other NFC charging device at a power transfer rate of up to one watt. The NFC WLC currently specifies power levels ranging from 100mW – 1W transmitted and data rates up to 106 kb/s, but NuCurrent claims to have gone beyond WLC specs, delivering over 3x more wireless power and over 8x faster data speeds. This was achieved with the company’s NuEva Development Platform for Near-Field Communication (NFC) Wireless Charging technology that provided up to 3W of power received (as opposed to just transmitted in the WLC specification) and data rates of up to 848 kb/s. NuCurrent expects the higher NFC charging power and data rates to enable new applications for small, space-constrained devices including wrist-wearables, smartwatches, styluses, […]
