NEA's Technology Platform
NEA’s core technology platform, which we call “NuumaTM”, is a gas sensor in the form of a chip, based on nanomaterials and capable of detecting airborne gases at the parts-per-billion (ppb) level. (“Nanomaterials” are materials sized in at least one dimension between 1 and 100 nanometers, with a nanometer being 10−9 of a meter.) The sensor is small and high density, and built to allow the real-time detection of multiple airborne chemical molecules simultaneously at a low power consumption rate. Using singled-walled carbon nanotubes (SWNT) and solid state electrical sensing, Nuuma is being designed to increase performance while reducing the cost and footprint of the sensing mechanism.
NEA's Sensor Chip
NEA’s core technology rests in a tiny sensor chip comprised of a nanomaterials-based conductometric sensor capable of detecting gases at the parts-per-billion (ppb). This sensor is high-density and built to allow real-time detection of multiple airborne chemical (gas) molecules simultaneously. Our plan is to design the Nuuma sensor to be miniaturized and run using extremely small amounts of power to greatly expand the type, location, reliability, flexibility and accuracy of its operation in diverse settings and for diverse applications. For example, Nuuma chips could be incorporated into small wearable devices (such as activity trackers or smartwatches), allowing consumers to monitor the air quality around them in real time.
We believe NEA has the capacity to develop gas-sensing products that will represent a substantial improvement over existing technologies. This is because existing technologies are very specific as to which chemical substances (or “analytes”) they can detect and how they detect them. NEA’s technology would include replaceable nanosensor chips, useable in either NEA or third-party devices, which could detect a variety of analytes at the same time. In addition, our sensors would be small, easily portable and consume little power. We envision that once our products are fully developed and commercialized, customers would be able to customize their monitoring systems by ordering and installing sensors specifically targeted to one or more analytes of their choosing.
NEA’s technology may potentially be used in a wide variety of additional industry sectors, including agriculture, the food and beverage sector, water quality, the military, public safety, manufacturing and the medical sector. The detection of Volatile Organic Compounds (VOCs) may be an area of particular opportunity. VOCs are organic chemical compounds whose composition makes it possible for them to evaporate under normal atmospheric conditions of temperature and pressure. They are emitted by a variety of solids and liquids, including common household and workplace items such as paints and lacquers, paint strippers, aerosol sprays, stored fuels, cleaning supplies, pesticides, building materials, furnishings, permanent markers, copiers, printers and craft materials including glues and adhesives. Some VOCs are known to have short and long-term adverse health effects.
