xMEMS Labs showcases micro-actuators and active cooling chips for wearable devices
At the xMEMS Live Asia 2025 event held in Taipei, xMEMS Labs showcased its Sycamore-W micro-driver unit designed for wearable devices, and its µCooling micro-active cooling chip for smart glasses and other wearable devices. The chip boasts a fanless design, aiming to expand its market reach. ▲xMEMS Labs launches µCooling micro-active cooling chip for smart glasses and other wearable devices. xMEMS Labs stated that the Sycamore-W micro-driver unit, designed for wearable devices, uses the same underlying technology as its solid-state cooling chip. It is waterproof, dustproof, and even shockproof. However, unlike the solid-state cooling chip which uses low-frequency cooling for heat dissipation, the Sycamore-W uses high-frequency cooling, emitting bright sound through small holes on the side, and adding richer low-frequency bass. Compared to traditional transflector diaphragm sound generation designs, Sycamore-W is only 1mm thick and weighs only 150mg. It reduces the volume by approximately 70% compared to current sound-generating units used in smartwatches (approximately 20 x 4 x 1.28mm), allowing manufacturers to incorporate larger batteries or more sensors into smartwatches. ▲xMEMS Labs states that Sycamore-W occupies a smaller volume, even smaller than the sound module used by Apple in the Apple Watch (the component at the top of the photo). Regarding the "µCooling" micro-active cooling chip for wearable devices such as smart glasses, its overall size is only approximately 9.3 x 7.6 x 1.13 mm. It can be directly integrated into the frame of smart glasses and effectively reduces the surface temperature of the device by up to 40%, allowing smart glasses to achieve 60-70% or higher performance while preventing users from experiencing discomfort due to high temperatures during extended wear. Unlike traditional fans, "µCooling" uses a solid-state vibration module to drive airflow, operating almost silently and without vibration, making it ideal for wearable devices that are sensitive to sound and have extremely limited internal space. ▲xMEMS Labs has launched the "µCooling" micro-active cooling chip for wearable devices such as smart glasses. They state that this technology can significantly improve the throttling or discomfort caused by overheating in smart glasses, while also enhancing reliability and all-day wearability. ...
