We miniaturize electrochemical gas sensors on microchips for the first time using a combination of our MEMS-like sensor designs and novel materials. For 50 years, electrochemical gas sensing has become the gold standard, but this technology has yet to become "chipified" like so many other sensing technologies found in our devices today. We bridge this gap for the first time in history and will not only replace the millions of electrochemical gas sensors used today, but unlock new markets where only a microchip sensor can be used. We have already begun to do this with our customers.v
