Sensor Technology: A Critical Cutting Edge of Exposure Science
We begin with a useful thought experiment: what will be the state of exposure science 10 years from now? In considering this question, it is hard to imagine sensor technologies not being an important theme. We believe that sensor technologies do, and will continue to, define the cutting edge of exposure science, now and in the future. In this issue, we see the breadth and depth of sensor use and methodological development that spans across the globe. It provides a robust snapshot of the diverse and varied approaches in which sensors can provide actionable data leading to health protective changes. In this special issue, these topics are delineated into four broad categories of work: associations between sensor measurements with health endpoints, characterizing microenvironments of individuals, and two areas of assessment in locations where there is limited data – one that evaluated traffic-related pollutants, and another assessing clean cook stove efficacy and policy.
