A UK start-up is developing the smallest gas flow sensor (see the picture). The patented combination of materials, processes and design enables enhanced interaction of the sensing elements with the gas flow, resulting in measurements with high precision, a wide range, and fast response in a miniaturised package. The repeatability is good with no drift. Such sensors can be integrated like a microelectronics component.
The sensor has already generated interest in areas where current sensors are a bit bulky and not cost-effective, for example wearable medical sensors. The biggest market promises to be smart buildings where air flow sensing is only starting to happen at scale. The second picture illustrates some use cases. The small sensor can be fitted into PM2.5 (Particulate Matter: fine inhalable particles, with diameters of 2.5 micrometers and smaller), or filter-monitoring sub-assemblies or drive the functionality of the air conditioner or demand controlled ventilation unit.
The company wishes to collaborate with R&D and product managers of manufacturers of systems for smart buildings, air quality control, wearables etc. Evaluation kits are available for fast and smooth testing. The likely type of co-operation is commercial agreement with technical assistance. Upon real interest, supply can be ramped up quickly.
