Dartmouth College Researchers Invent Real Time Secondhand Smoke Sensor

Published: Mar 21, 2013

Making headway against a major public health threat, Dartmouth College researchers have invented the first ever secondhand tobacco smoke sensor that records data in real time, a new study in the journal Nicotine and Tobacco Research shows. The researchers expect to soon convert the prototype, which is smaller and lighter than a cellphone, into a wearable, affordable and reusable device that helps to enforce no smoking regulations and sheds light on the pervasiveness of secondhand smoke. The sensor can also detect thirdhand smoke, or nicotine off-gassing from clothing, furniture, car seats and other material.
