Abstract

A unique solid-state optical sensor configuration has been invented that can serve as a development platform for a host of chemical and biochemical sensors in either gaseous or liquid environments. We present results from measurements from the first adaptation of the device to oxygen sensing via fluorescence quenching and note the distinct advantages over existing electrochemical and more recent fiber-optic methods. The platform technology itself features greatly enhanced energy efficiency, high sensitivity, low-power consumption, ease of miniaturization, low cost, high-volume manufacturability using standard methods, very fast response/recovery profiles, and high reliability. The oxygen sensor embodiment has been demonstrated to operate well over the temperature range from -20 to 50 degrees C, not to be interfered with by other common gases including water vapor at high levels, and capable of response times less than 100 milliseconds.
