About Sundip R. Doshi
Sundip R. Doshi is Founder and CEO of AerNos, Inc., a nano gas sensor company.
We take 20,000 breaths every day, and with each breath we are vulnerable to invisible, harmful gases in the environment. In many cases, these gases can have a negative impact on our health. Technology is enabling people to take better care of their health – through monitoring and access to information. However, with air pollution, we have not been able to act on our personal exposure to harmful airborne gases because there has been no way to monitor what’s in the air we are breathing. Interest in understanding safe and potentially unsafe levels of these pollutants has spawned a variety of gas sensors for consumer use. Existing gas sensors, however, fall short in key areas. Most gas sensors can detect just one or two gases, a fraction of the harmful gases that could be present in the indoor or outdoor environment. Fewer still can detect at parts-per-billion (ppb) levels, which further limits their value as detecting ppb for many harmful pollutants, but this is essential to environmental monitoring. Lastly, many existing gas sensors require high operating power and take a long time to provide a reading – up to fifteen minutes. AerNos AerCNT Technology employs hybrid nanostructures and MEMS circuitry to build a gas sensor that dramatically improves pollution monitoring capabilities. AerNos’s miniature gas sensors use doped nanomaterials such as carbon nanotubes because of their stability, sensitivity and selectivity to target gases and can simultaneously detect multiple gases to the ppb within seconds while drawing minimal power. Rather than use a traditional CMOS foundry, AerNos is working with Rogue Valley Microdevices, a precision MEMS foundry comfortable with advanced materials, to manufacture its gas sensors. Together with its MEMS foundry partner, what challenges did AerNos overcome to manufacture a gas sensor array created with multi-layer hybrid nanostructures? AerNos will describe at a high level how it formulated configurations of doped carbon nanotubes, conducting polymers – coupled with hybrid nanomaterial structures — to create tiny, highly sensitive, low-power MEMS gas sensors that can detect multiple gases simultaneously to the parts-per-billion.
