Henrik Rödjegård is the CTO of the Swedish NDIR gas sensor producer Senseair. He is also an adjunct professor in electronics design at Mid Sweden University. Henrik started his professional career with a Ph.D degree in solid state electronics from Chalmers University of Technology, Göteborg, Sweden in 2005. His thesis focused on MEMS technology and analogue electronics for inertial sensors such as accelerometers and gyroscopes. The technology developed during that period is still used for navigation of new satellites. Since 2006 Henrik has been part of the research team at Senseair improving gas sensing technology. This includes low-cost carbon dioxide sensors, greenhouse gas mapping and alcohol breathalyzers without mouthpiece for vehicle integration.
