Synkera Technologies, Inc. has received a SBIR Phase I grant from the National Institutes of Health to develop
improved ozone sensors capable of making reliable in-field exposure measurements for individuals with asthma and
other respiratory diseases. The ultimate goal of the project is the development and validation of a new, personal
monitor that will be able to detect low levels of ozone (<12 ppb) in real-time with the required spatial resolution in
order to aid research on respiratory diseases, leading to a better understanding of how people are affected by various
environmental exposures. Exposure to elevated levels of ground level ozone has negative health impacts on
susceptible individuals, particularly children. Susceptible individuals can readily experience respiratory system
irritation, reduced lung function, inflammation and damage to cells that line the lungs, aggravation of chronic lung
diseases, and possibly permanent lung damage.
The sensors will build upon recent advances in electrochemical sensing technology to create a next generation
product that is significantly smaller, faster, more sensitive, stable and lower cost than any electrochemical sensor
available today. There are three primary aspects to this innovation: integration of a solid polymer electrolyte (SPE)
for leak-free, stable operation; the use of ultra-small electrodes (nano-dots) featuring nanometer length scales for
increased sensitivity; and the use of a unique substrate (nanoscale anodic aluminum oxide) and manufacturing
techniques for low cost, reproducible mass production of the novel sensor architecture. A fourth important aspect
of the proposed work is addressing potential cross-interference through sensor operation. These features are key to
creating a sensor device that is small, low power, sensitive and selective enough for use in accurate and reliable
personal monitors that will dramatically exceed the performance of devices
currently on the market.
Key features of the sensing device include:
o excellent sensitivity to ozone (~10 ppb)
o selective versus NO2 and formaldehyde
o negligible effects from changing humidity levels
o low cost (less than $100 per device)
o stable response over time
o long storage and operational lifetime
