We know that the air we breathe in isn't the cleanest. Polution is everywhere. But wil lyou be willing to wear this RTI International's Micro PEM - personal exposure monitor, which measures the adverse affects of breathing in all that poison.

Hopefully we don't have to be all wearing this one day when the air quality becomes so bad. The MicroPEM will measure the levels of pollutants in the air as well as an individual's physical activity using acceleration and motion sensors.

Researchers will be able to calculate a person's varied breathing rates as they perform different levels of physical activity.
