Wi-fi-power–tech firm NuCurrent has developed the primary near-field-communication–powered headset-charging tech—which an HP firm referred to as Poly is utilizing to make a brand new, fast-charging, light-weight, over-the-ear headset, NuCurrent CTO Alberto Peralta instructed EE Occasions at this time. NuCurrent’s NuSync resolution is the very best energy implementation of near-field-communication (NFC) charging tech so far, he added.
The Poly Voyager Encompass 85 UC Bluetooth headset, designed for individuals working each within the workplace and from residence, will promote for just below $500.
The design problem for the headset: facilitate quick, seamless charging coupled with a light-weight headset in order that customers may simply put on the headset for the workday.
“To attain 4 to 5 hours for charging, we would have liked to considerably enhance the quantity of energy transmitted by the charging stand past what anybody had ever accomplished in near-field communication,” Peralta stated. “The aim additionally was for wi-fi charging to look invisible.”
As a part of that desired invisibility, the charging station has no pins, permitting for straightforward alignment, he stated.
The NuSync system additionally requires no connections, Peralta added.

“Historically, gadgets like good watches have relied on bodily connectors to meet two elementary wants: energy supply and information switch,” he stated. “To attain a genuinely wi-fi ecosystem, it’s crucial that wi-fi options handle each these necessities seamlessly, not only one or the opposite, which is what we’ve seen in gadgets till this level.”
The improved expertise allows higher communications for customers and for updates, in accordance with Peralta. “We’re not solely transferring energy, we’re transferring information. The 2-way communication between the headphones and charging stand may permit for seamless firmware updates and for diagnostic data retrieval throughout charging.”
In 2021, NuCurrent developed a wearable, wireless-charging battery pack for the WHOOP 3.0 health tracker that receives energy at 1.2 watts, Peralta stated, including that the following finest efficiency from different corporations is 300 milliwatts.
“The Poly headset design receives energy at 1.8 watts,” he stated. “That’s 50% greater than what we had and 6 occasions extra energy from what anyone else had accomplished.”
The headset weighs 275 grams, lower than Apple’s AirPods Max headset, which weighs 384.5 grams. That lighter weight interprets to extra consolation for customers. “One of many advantages of NuSync expertise is that it gives extra flexibility in industrial design, as we will see with this utility. I exploit all of them day, they’re tremendous snug,” he stated.
The headset gives clear audio, through a high-quality boomless microphone, and as many as 21 hours of discuss time, in accordance with the corporate.
This challenge was NuCurrent’s first utilizing its digital design automation (EDA) instruments that make use of AI and machine studying—and this innovation made it doable to finalize the design and get to market in a a lot shorter timeframe than beforehand skilled, Peralta stated.

Potential use instances past this headset embody wearable gadgets, similar to good watches, good glasses and ear buds. Different potentialities embody laptop peripherals, similar to wi-fi charging mice, and implantable medical gadgets, similar to neuro-stimulators for continual ache, pacemakers, cochlear implants and gadgets for treating sleep apnea, he stated.
