Recent years have witnessed an explosion of chemical and physical sensing technologies driven by the Internet of Things (IoT), the advent of commercial wearable technologies and the rise of point of care diagnostics .  Business analysts expect  these trends to continue to grow substantially over the next decade.  This growth will provide ever increasing opportunities in sensor science and technology, particularly those aimed at wearables, as well as medical diagnostics and general health and wellness awareness in the home and environment. 

This presentation will review some of our recent work in the area of next-generation electrochemical gas sensors for environmental and health/safety applications.  Specifically, we will present on new hardware developed for wearable and other applications requiring ultralow power operation and its application to several areas including ozone monitoring for asthma sufferers, wearable environmental gas sensors and the detection and characterization of odors.
