With increasingly small electronic devices, the space is lacking to properly evacuate heat. The solution could be an innovative “fan” fan, the XMC-2400 of xmems, which is only a millimeter thick.
All electronic chips heat during their operation and this heatheat must be dissipated to avoid overheating that can damage them. On a desktop computer, just a large block of metalmetalthe radiatorradiatorsurmounted by a fan. In laptops and smartphones, space is lacking and manufacturers must innovate. One of the techniques used is the steam room, which uses a liquidliquid which evaporates under the effect of heat, then condenses against a less warm wall.
However, this will not be enough for some even smaller devices, such as intelligent or augmented reality glasses. For the latter, the manufacturer Xmems has just announced a new technology called “Fan on chip”.
This cooling system is tiny, or 9.3 per 7.6 millimeters, and only 1.13 millimeter thick. It’s smaller than a microSD card.

A fan that adapts to many devices
Baptized XMC-2400it is an active, but inaudible, and water and dust resistant system (IP58). He uses an electromechanical microsystem (even) composed of a layer piezoelectricpiezoelectric who moves a membrane of siliconesilicone at ultrasonic frequencies. This allows you to vacuumairair Fresh on the top of the chip, or on one side, and to expel hot air on another side, thus creating an air flow without perceptible noise.
Smart glasses are currently consuming between 0.5 and 1 wattwattbut with their rise in power they should soon consume 2 watts or more, which may make them hot to the touch. Xmems indicates that its flea fan should reduce the temperature by 40 %.
This technology is not only intended for smart glasses. It should also be able to be used on smartphones, laptop computers, and even external hardware and hard drives. THE XMC-2400 is small enough to be added to all components that generate heat, such as processors, graphic fleas or memory or battery. In addition, XMEMS uses this same technology to offer micro-haut-runners that can be integrated into many devices such as earpieceearpiecehearing aids, smartphones, or connected watches.
The manufacturer indicates that the first samples of its fan on chip are already available and plans to start production on a large scale in the first quarter of 2026.
