Computer scientist Shreta Chalen (人名) and his team are developing new sensing systems.

“Initial focus was really around energy and water monitoring. ”

They built a new generation of smart sensors that monitor electronic interference on a home’s power line or water pressure changes in the plumbing. Most of these technologies has already found industrial applications. And for Chalen’s team, turn their attention is about adapting the technology for personal health monitoring.

“So how do we take this noise and make it into a signal of interest? …Was kinda… kinda the core of what we did for many years. And we are taking that work and applying it into other domains.”

They are looking to take advantage of all the functionality built into our smartphones. With the users’ permission, this app can use a microphone, built into most smartphones, to listen to background noises. (coughing) Such as coughing, searching for patterns that suggest that a trip to the doctor might be in order.

“With constructive models, we are trying to understand how sound works, how it… what its patterns are. We give a whole bunch of examples of different kinds of audios, things like, uh, people talking, people laughing, sneezing and of course, coughing.”

This app uses a phone’s camera to check HU levels in blood, by analyzing the colors of capillary fluids through the skin.

“Generally, what happens is that phronimids might be a little less red and we took advantage of that, by say, putting your finger over a camera of the phone, the camera of the phone can actually see the coloration of the blood.”

And this test uses the camera to tell parents worried about jaundice in new born infants.

“Now, jaundice is something that doctors, who have seen tons of babies have, they just just can’t figure out at a very basic level of, is this baby… do they need to get treatments or they are in a good condition. Well, the first-time parents have no idea what the jaundice might necessarily look like. ”

　　The researchers say the built-in sensors found in smart phones are already commonplace, but the applications and their implications for our health and well-being may be more far reaching than we ever imagined.
