xMEMS Raises $21M Series D to Accelerate Commercial Scale of Breakthrough piezoMEMS Technologies for AI-Enabled Consumer Devices
The new capital will accelerate mass production and global commercialization of xMEMS’ piezoMEMS-based loudspeakers and micro-cooling chips – two innovations that directly address the fundamental design and performance constraints impacting the next generation of AI-enabled consumer devices.
“This fundraise comes at a moment of rapidly accelerating commercial momentum,” said
“xMEMS is at the heart of a significant shift in hardware design driven by AI,” said
xMEMS has pioneered a new category of semiconductor technology: piezoMEMS, a monolithic MEMS platform that leverages thin-film piezoelectric materials to deliver performance previously unachievable at such small scales. Unlike legacy coil motor speaker and fan components, piezoMEMS speakers and micro-coolers are fully solid-state, enabling a leap forward in performance, reliability, and form factor – critical to enabling thinner, lighter, and higher-performing edge AI products.
Over the past year, xMEMS has brought to market two flagship product families built on this breakthrough platform:
- Sycamore, the world’s thinnest and lightest high-fidelity MEMS loudspeaker, designed to deliver rich, full-range sound in ultra-slim form factors like AI glasses, headphones, and smartwatches.
- µCooling, the industry’s first chip-scale, solid-state air-moving solution, providing silent, vibration-free active thermal management in space-constrained devices such as AI glasses, smartphones, and SSDs.
Together, these innovations are transforming how device makers solve for rising compute loads, thermal budgets, and audio clarity in AI-native product designs. Many of the world’s leading consumer technology companies are now engaging xMEMS as they architect their next-generation AI devices.
xMEMS’ leadership in piezoMEMS has been recognized with over 250 granted patents and industry accolades including Best MEMS Solution and Startup of the Year at Sensors Converge 2025. With commercial engagements rapidly expanding, the company is emerging as a key enabler of the next generation of AI-powered consumer and edge devices.
The Series D investment marks a major inflection point in xMEMS’ trajectory – enabling full-scale production, deeper partnerships with global OEMs, and continued R&D to unlock the next wave of piezoMEMS breakthroughs in audio, thermal, and beyond.
