“Extreme low power” chip with energy harvesting provides lifetime battery solution for remote controls

QuickSet extreme low-power-energy-harvesting chip remote controls

Most people probably don’t mind changing batteries in remote controls every so often, but it contributes to e-waste especially if you’re not using rechargeable batteries, and I always find it’s pain as I don’t usually have stock, or don’t feel like waiting for several hours to recharge the batteries. Universal Electronics Inc, or UEI for shorts, claims to have a solution with a family of QuickSet-certified chips using “Extreme Low-Power”, energy-harvesting and “high-performance technology” that would provide lifetime battery life to Bluetooth, voice remote controls. The main goal is “to help transition the world towards a more sustainable future, by reducing primary battery waste throughout the life of the product, which in turn reduces the cumulative CO2 footprint”. We don’t have a lot of information about the chip, but the company provides some of the key benefits of the Bluetooth 5.2 SoC: Arm-based with Trustzone security Up to 2.5 times […]

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 […]
