-MIT Spectrum, by Elizabeth Thomson -June 3, 2014: -- Trucks and other heavy-duty vehicles could run more efficiently while cutting tailpipe emissions, thanks to a discovery in an MIT lab that, with the help of the Institute’s entrepreneurial ecosystem, is now the focus of a start-up that has drawn attention — and funding — from the National Science Foundation and the Department of Energy... Alexander Sappok PhD ’09, was a graduate student in mechanical engineering at MIT’s Sloan Automotive Lab when he and Dr. Leslie Bromberg realized that the radio-frequency (RF) signals key to transmitting data to and from cell phones and other wireless devices might also solve a problem in the automotive industry. Their basic concept: The signals could be analyzed to monitor the buildup of soot in the high-tech filters that prevent trucks and buses from spewing black smoke along our roadways... “It turns out that the carbon in soot is really good at absorbing RF signals. So the more soot in the filter, the weaker the RF signal gets, and we can measure that directly in real time,” says Sappok, president of Filter Sensing Technologies (FST), the company he started in 2008 while still a student...
