xMEMS begins mass production of XMC-2400 and XMC-4800 micro‑cooling chips

The chips use a piezoMEMS platform that creates directed airflow through ultrasonic vibration of thin‑film piezoelectric membranes, eliminating rotating fans. xMEMS reports that customers have seen temperature drops of 10–25 °C in tests across glasses, smartphones and SSDs, but the announcement does not name the devices or describe the test methodology, so the figures are illustrative rather than guaranteed. The firm argues that such active cooling could help edge AI wearables and compact storage maintain sustained performance, though the added power draw, integration space and cost remain open questions.

Mike Housholder, vice‑president of xMEMS’ Thermal Management Business Unit, frames mass production as a step toward scaling demand and possibly co‑packaging the silicon architecture with edge AI processors. The real impact will become clearer once integrated products reach the market.
