Wireless Charging for Wearables and Beyond

Wireless power industry authority surpasses power and data speeds of NFC WLC specification within months of standard being published.

NuCurrent's NuEva Development Platform for Near-Field Communication (NFC) Wireless Charging technology delivers over 3x more wireless power and over 8x faster data speeds.

The NFC Forum’s Wireless Charging Specification (WLC) currently specifies power levels ranging from 100mW – 1W transmitted and data rates up to 106 kb/s. Based on wireless power expertise and complementary technology, including over 180 patents granted or pending, the NuEva NFC Wireless Charging Development Platform can provide up to 3W of power received and data rates up to 848 kb/s. 

“Charging up to 3W or 848 kb/s of data may sound like an incremental innovation, but when you survey all of the real-life products operating within those requirements, and then add the business benefits that NFC technology can bring, you start to realize the major impact that extended wireless charging and data will have,” said EVP of Sales and Marketing Tim Tumilty. 

Operating at 13.56MHz, NFC Wireless Charging utilizes a single antenna to deliver both communications and low amounts of power, making it a solution for devices that are incompatible with Qi – or non-standard low frequency – wireless power solutions

“Most people are familiar with NFC for its popular use in mobile and contactless payment, identity documents, and key cards, but are unaware of its extended wireless charging capabilities,” said Tumilty.

NFC Wireless Charging brings innovation to devices such as wireless charging hearables, fitness trackers, computer peripherals, smart glasses, and other small, space-constrained devices.
