Nanomaterial Characterization Using Actuated Microelectromechanical Testing Stages, Joseph James Brown
Mechanical Engineering Graduate Theses & Dissertations
In this work, microfabricated mechanical systems have been created in a variety of forms and operated to perform nanomaterials characterization tests. A simplified integrated test system was developed and used to collect data from a range of materials including gallium nitride nanowires. A new force estimation approach was developed which enables estimation of the forces provided by electrothermal microelectromechanical (MEMS) actuators, and with knowledge of a material specimen cross-section area, an estimation of the engineering stress within the nanomaterial specimen.
In an expanded design, a MEMS micromanipulator probe interfaced with a removable specimen holder, also known as a test coupon ...
