AirSpeQ is commercializing sensors for fine and ultrafine airborne particulate matter (PM) detection and monitoring. The technology is based on patented proprietary MEMS thin-film bulk acoustic resonator (FBAR) technology, and leverages more than 12 years of R&D at the University of California at Berkeley and Lawrence Berkeley National Laboratory. Consumer sensors available today monitor superficial, visual and or olfactory air pollution because that is all they are able to measure. AirSpeQ’s prosumer grade technologies leapfrog existing consumer solutions by allowing the accurate measurement of the most pernicious small particulate matter that can not only penetrate the lungs but also the brain and blood system. In contrast to consumer sensors, AirSpeQ’s prosumer technologies accurately measure PM across the full range of concentrations, are reliable across a range of environmental operating conditions, have a smaller form factor, consume less power, work longer without preventative maintenance and cost substantially less.
