4K-MEMS Technology
Too small to see, too bright to ignore.
4K-MEMS broadband IR emitters are the world’s first thermal emitter ready for the consumer market: sized to be embedded in the smallest of spaces., manufactured and packaged at a wafer scale to allow mass production.
We build lighting solutions that seamlessly integrate with tomorrow’s sensing platforms. By customizing the illumination to the application, our emitters set a new standard for infrared lighting. The micro-emitters are based on inspired designs, novel material development, and cutting-edge wafer level micro-manufacturing processes.
Broadband IR, where you need it, when you need it.
Our Mission
4K-MEMS SA develops disruptive miniaturized light sources enabling new architectures in machine vision, hyperspectral imaging, and portable spectroscopy. Our revolutionary light sources are designed for deep integration in embedded analysis modules. 4K-MEMS provides NIR/SWIR integrated lighting solutions needed for these emerging applications.
4K-MEMS addresses the growing need for quality broadband IR illumination, resulting from the recent technology breakthroughs in IR detection, chip-sized sensor modules, and evaluation algorithms. Soon, chemical identification will become ubiquitous in consumer electronics – including cell phones. 4K-MEMS will help make that happen.
Current projects
BRIGHTIR is bringing infrared-based chemical sensing out of the lab and into portable, wearable, and point-of-care devices through ultra-compact, efficient emitters designed for scalable, low-cost manufacturing. Infrared light reveals chemical information invisible to the eye, from CO₂ in the air to biomarkers in fluids and trace compounds in the environment. Today's large, costly instruments are no longer the only option. 4K-MEMS leads emitter development, creating a compact thermal infrared emitter chip for high-volume manufacturing to enable non-invasive wellness and environmental sensing at scale.
OMICSENS is building a groundbreaking omics measurement platform to improve non-small cell lung cancer (NSCLC) prognosis through timely, accurate detection of Tyrosine Kinase Inhibitor (TKI) resistance linked to Epidermal Growth Factor Receptor (EGFR) mutations. 4K-MEMS develops novel materials and SWIR emitter arrays for a platform that integrates a nanophotonic biosensor, highly absorbent nanochip, metamaterial-based detector with AI-driven analyte quantification, and a microfluidics system for efficient sample delivery, adaptable to optimize treatment across various cancers.
HyperImage aims to deliver a versatile, fast, and affordable spectral imaging platform spanning long- and short-range applications, with technical goals covering new photonic components, high-performance sensors, and advanced tunable optics. 4K-MEMS contributes novel 1D emitter array modules for line illumination, while the broader project integrates lightweight spectral imaging systems into robots and vehicles, enables cloud-based image analysis, supports modular designs for automated material analysis and quality control, and establishes commercialization paths and European value chains across key markets.
