A journal article authored by ME PhD student Rachel Vitali was selected as a Featured Paper by the journal Sensors in September 2017. Her paper, titled “Method for estimating three-dimensional knee rotations using two inertial measurement units,” introduces a new way to measure rotations across the knee using data from two IMUs mounted on the shank and thigh. This paper provides compelling evidence of the method's accuracy by comparing to highly resolved measurements from optical encoders. This paper can be found in Sensors, vol. 17, no. 9, September 2017.
