A New Frontier for Air Sensors 2014

Compact air quality sensor fits in the palm of your hand.

The wearable market has expanded its product line—from smart glasses and smart watches to dozens of different fitness tracker wristbands and T-shirts that interact with the world around you.

What you don’t see in these gadgets is the tiny technologies that make it possible for your T-shirt to light up or for you to tap your wrist and see how many calories you’ve burned.

Similar to how computers shrunk from the size of rooms to the size of your front pocket, sensors have also been developed in ever decreasing dimensions.

One of the major applications for EPA: sensors that measure air quality. Agency researchers and others can use these portable, real-time sensors in the environment to gain a more intricate picture of what’s happening in our communities.

We’ve hosted a competition won by a design for a wearable sensor that estimates a person’s exposure to air pollution. EPA grants fund broad cookstove research, some of which includes the use of air sensors to measure pollution from indoor cookstoves.

Last fall, EPA collaborators published a seminal paper on the sensor revolution in a top journal, Environmental Science & Technology. The journal received more than 5,400 submissions in 2013 on a variety of topics, and EPA’s research won first runner-up for best feature paper.

One of the most important parts of this field of study is the diversity of people interested in the work.

Next week, we’ll hold an air sensors workshop to spark more discussions and continue this important work advancing innovative air sensor technologies by bringing together scientists, policy experts, technology developers, data analysts, and leaders from government, industry, and community groups.

To learn more about the opportunities and challenges that air sensors present, register for the webcast of our workshop on June 9-10.

We’ll live tweet the event from @EPAresearch using #AirSensors.
