Research article by Aneesh Koka and Dr. Henry A. Sodano entitled “High-sensitivity accelerometer composed of ultra-long vertically aligned barium titanate nanowire arrays” has been published recently in Nature Communications. A brief summary of the article is presented as follows
"Aligned piezoelectric nanowires show great promise for sensing applications, however it is yet to be demonstrated that they can be used as an accurate dynamic sensor. Here, Koka and Sodano demonstrate the first synthesis of vertically aligned arrays of ultra-long (~45 µm) barium titanate nanowires and their application as a nano electromechanical system accelerometer that offers high sensitivity"
