A plastic microbelt that vibrates when passed by low-speed airflow could lead to a new generation of microscale biomedical devices that are powered by human breath.
The wireless capsule works alongside a belt that also tracks skin temperature, pulse, and respiration rate and is being used this year in the fight against bush fires in Australia.
The 2-inch-wide sensor, which tracks heart rate, respiration, and movement, is non-invasive and wearable.
A team at MIT is using widely available low-res Webcam imaging to measure the human pulse, and is now working on expanding readings to respiration and blood pressure.
German research institute has come up with a PDA that measures your respiration.
