Frame freedom without pogo pins.
Frame freedom without pogo pins.
Every smart glasses program eventually faces the same decision. Keep pogo pins and accept that every frame shape needs a custom charger, or move to wireless power and design frames as industrial designers want to design them. NuCurrent builds the wireless power architecture that makes the second choice possible.
Pogo pins do not scale to fashion.
Pogo pins do not scale to fashion.
Smart glasses are moving out of the gadget category and into the fashion category. Frame shapes proliferate. Fashion SKUs multiply. Retail channels demand variety. Pogo pin charging works against every one of those dynamics, because every new frame needs a new charging case, custom tooling, and its own inventory.
The alternatives get worse. USB-C ports compromise sealed design, weight and aesthetic. Exposed contacts corrode. Magnetic pucks limit form factor. All forms of contact charging are incompatible with the aesthetic that makes glasses desirable in the first place.
Wireless power is the only scalable answer. But building it into glasses is hard. Coil placement competes with electronics, optics, and industrial design. Power transfer must work at the awkward geometries of a folded frame. Thermal behavior has to be imperceptible on skin contact.
The frame and the physics have to converge.
The frame and the physics have to converge.
Smart glasses coil design is unforgiving. The coil sits inside a temple arm that is already crowded with battery, antenna, silicon, and hinge. A design that is a few millimeters off spec can shift efficiency, charge speed, and user comfort. A design that leaks flux into the optics breaks the display. General-purpose simulation tools take days to converge on a single coil geometry.
GenA does it in minutes. We iterate across geometry, frequency, shielding, and thermal envelope in the same afternoon that our customers’ ID teams are reviewing frame sketches.
This is why our customers’ glasses ship with forwards and backwards compatibility guaranteed. The industrial design converges with the physics, not against it.

Smart glasses programs require NFC Wireless Charging because the power levels, form factors, and certification path say so. It comes down to physics. We sit on the NFC Forum board that governs this specification and our platform is built with foresight from the start.
