For decades, physical connectors have been a weak point in device design. They create vulnerabilities—entry points for water, dust, and daily wear. They add cost and complexity to manufacturing. And according to ABI Research, connector-related failures are among the most common in rugged electronics.
Connectorless wireless charging offers an elegant solution—and NuCurrent is helping lead the charge.
Why It Matters
A fully sealed device is more than sleek—it’s strategic. In rugged, wet, or hygiene-sensitive environments, eliminating mechanical charging ports directly improves product longevity, safety, and ROI.
Take the Honeywell Dolphin CN80/CN85 handhelds, for example. These devices, which use NuCurrent’s wireless power system, removed exposed contacts to support sealed, field-ready operation that endures harsh logistics conditions.
On the consumer side, WHOOP 4.0 used the same core innovation. By removing copper charging contacts and implementing NuCurrent’s NFC wireless charging, the device achieved an IP68 waterproof rating (it’s dustproof and water-resistant up to 10 meters for 2 hours)—and did so in a 33% smaller footprint.
What Connectorless Charging Enables
- IP68 Waterproofing
NuCurrent designs support fully sealed devices, from fitness trackers to medical patches. - Fewer Mechanical Failures
Fewer physical connections mean fewer points of failure. (See ABI Research’s analysis of connector vulnerabilities.) - Streamlined Manufacturing
Eliminating pogo pins simplifies assembly, improves sealing, and reduces cost. - Wireless Testing and Updates
Our over-the-air UART capabilities let partners test, debug, and program devices wirelessly during production.
How NuCurrent Does It
With over 400 patents, NuCurrent leads the industry in antenna design and NFC power integration. Our Multi-Layer Multi-Turn (MLMT) coils and NuEva NFC Development Platform support wireless power and data in ultra-compact devices.
We enable up to 1.2W of power and 424 kbps bidirectional data—in specific configurations like Qi-NFC hybrid mode—making us the only provider to ship this level of performance at scale.
These aren’t lab tests. They’re commercial devices—millions of them—already in users’ hands.
Who Should Pay Attention
- Wearable OEMs seeking sleeker, tougher designs
- Industrial manufacturers wanting IP68 protection and reliability
- Healthcare innovators building sealed biosensors and patches
Connectorless wireless charging is no longer a “nice-to-have.” For the next generation of wearable and rugged devices, it’s a competitive edge.
NuCurrent offers the IP, the engineering, and the real-world deployment history to get you there.
