Lelantos develops compact gas-sensing chips that combine MEMS resonator arrays and sensing materials with conventional CMOS silicon for low-power, connected monitoring. Founded by semiconductor and electrical-engineering researchers, the company is applying this technology to persistent leak detection and air-quality monitoring, with additional uses in medical diagnostics and industrial safety. Its founders bring experience from Columbia University, Brown University, and Raytheon Technologies to the effort.
N5 Sensors, IncRockville-based N5 Sensors builds semiconductor-derived chemical sensors and autonomous detection platforms that give machines real-time awareness of hazardous gases and vapors. Its SPH™ microsensor core combines on-device AI with cloud analytics across fixed, wearable, and mesh-network systems, serving applications from defense and emergency response to event and infrastructure safety. Founded by semiconductor physicist Abhishek Motayed, the company holds seven patents and designs its sensing core for calibration-free, over-the-air-updatable operation.ROCKVILLE, MD
IR Sensors & SystemsFounded in 2016 by veterans of the semiconductor and MEMS industry, IR Sensors & Systems develops MEMS-based sensors and actuators, with its work centered on high-signal-to-noise-ratio microphones for compact devices. The company’s patented Integrated Contour Mesa design is intended to deliver strong audio performance with low power and smaller packages, while its team brings more than 90 years of combined semiconductor and microelectronics experience. IRS says its founders have received more than 17 U.S. patents related to MEMS microphone design, fabrication, and packaging.ROCHESTER, NY
SensorconFounded in 2003, Sensorcon has built its name around portable gas monitoring for people who need quick, dependable awareness of hazardous exposure. From its Buffalo, New York facility, the company makes and tests its Inspector sensors for professional users, while its ISO 9001:2015 certification reflects the quality system behind that work. Sensorcon also keeps its instruments in service through calibration and factory renewal programs.BUFFALO, NY
Industrial ScientificIndustrial Scientific makes connected gas detectors and safety software for hazardous workplaces, extending its work from methane-detection instrumentation into remote monitoring and safety management. Born in 1976 as the research division of National Mine Service and operating as an independent company since 1985, it developed the first three-gas, six-gas, and wireless gas monitors. The Pittsburgh-based company has more than 1,300 employees worldwide and holds ISO 9001, ISO 14001, and ISO 45001 certifications.PITTSBURGH, PA
