Zensi, a research startup that uses simple technology to monitor home electricity and water use, has been acquired by electronics company Belkin International Inc. The startup was based on technology developed by Shwetak Patel, a University of Washington assistant professor in the departments of computer science and engineering and electrical engineering.
 
Patel co-founded Zensi in 2008 while pursuing his doctorate at the Georgia Institute of Technology. The startup was initially based on his thesis research and Zensi had licensed technology from Patel's research group at the UW.
