WAIC 2026 Puts AI Glasses in the Spotlight
At the World Artificial Intelligence Conference 2026 in Shanghai, AI glasses moved from concept demos to real, shippable products. Quark showed its AI Glasses S1, a flagship model built around a dual chip architecture that splits heavy AI vision tasks from low power always on functions such as Bluetooth and audio, paired with a passive cooling approach based on graphite thermal film and heat conducting materials. BleeqUp brought AI glasses designed for high frame rate sports recording, relying on a system level approach that balances on device AI workload against thermal output in real time. Moheng showed an AI plus AR pair that does not use active air or liquid cooling at all, instead keeping heat within a comfortable range through a tightly integrated edge AI chipset, a lightweight overall structure, and an efficient optical design.
Three different products, three different engineering choices, but all pointing at the same underlying issue. Once glasses are expected to run AI features continuously through a full day of wear, heat is no longer a minor detail buried inside the spec sheet. It becomes one of the things that decides whether the product actually works.

Cooling Glasses Is Not About Removing a Lot of Heat, It Is About Comfort in a Very Small Space
A phone or a laptop can tolerate a warm back panel for a few minutes. Glasses sit directly on skin, on the nose and around the ears, for hours at a time. That changes what good thermal design actually means.
For AI glasses, the real concerns are skin contact temperature, fan or pump noise next to the ear, added weight on the nose bridge, and how much of the battery gets used up just keeping the device cool. A cooling solution that works fine in a phone can be completely wrong for glasses if it adds even a few grams, makes any audible noise, or raises the frame temperature by a couple of degrees.
This is also why AI glasses thermal design is never just one component doing all the work. It is really a system problem that combines several things at once, the thermal conductivity of the materials used, how heat spreads out across the frame structure, how power is distributed between chips and functions, and in some cases, small scale active cooling elements working alongside all of the above. Getting any one of these wrong shows up immediately as discomfort on the user's face.
All of this cannot be just replicated from the phone design. A phone gets picked up, which is used and laid down for a few minutes, giving a warm phone time to cool off, before it becomes a problem. Glasses are in continuous direct contact with the skin during use, so that any heat created near the chip or battery must escape through the frame, and onto the user. This is the difference that means that simply scaling down a phone cooling solution cannot be expected to work for glasses makers.

Light Weight and High Performance Pull in Opposite Directions
Meta-Bounds's AI + AR glasses illustrate this tension well. The whole product, including optics, display, processor, battery and construction, the whole down to approximately 25 grams makes it an actual all days item, like a normal eyeglasses. Each gram that is taken off the glasses frame which can be used for making a larger battery, larger heat spreading surface, or any cooling component.
This means that optical design, display technology, chip choice, power delivery, thermal management are not separate problems they are solving one by one. All must be balanced and compressed as early as the design process begins.  
It's because of that thermal management is no longer a finishing touch, but a gating factor. It is possible for a brand to make a great fit, really custom optics, even a great AI assistant, but if after 30 minutes we find out the glasses to feel warm on the nose, or a thicker temple arm for a cooling part to fit, then it's a problem throughout. Getting the thermal side right early, alongside the optics and the chipset, is what allows a design team to keep both the weight target and the performance target, instead of sacrificing one for the other late in development.

Where BESTAR and COOLTIST Come In
Right now, most AI glasses on the market rely mainly on low power chip architectures, passive heat spreading materials, and smart software level power scheduling. True active cooling is still the exception rather than the rule.
That is likely to change as glasses take on stronger on device AI models and higher sustained processing loads. As power density inside these small frames keeps climbing, the industry will increasingly need compact active cooling modules that can fit inside a temple arm, along with more precise thermal sensing and closed loop control to manage them safely and quietly.
This is the direction BESTAR has built its thermal management division, COOLTIST, to address. Since being introduced under its own dedicated brand, COOLTIST has focused entirely on active thermal management for compact electronics, and continues to expand its product matrix around liquid cooling modules, piezoelectric fan modules, and small blowers and micro air pumps. These components are designed from the ground up for devices where every gram and every decibel counts, which fits naturally with where AI glasses are heading. Teams working on next generation smart glasses, or any other wearable pushing into higher power on device AI, are welcome to reach out to BESTAR and COOLTIST to talk through specific power, size, and comfort requirements.

What It Really Takes for AI Glasses to Go Mainstream
Whether AI glasses truly become a mainstream product will not be decided by the model or the interaction design alone. It will also depend on whether the device can stay quiet, comfortable, and stable through a full day of continuous wear, and that is a thermal engineering problem as much as it is a software one.
