Abstract:

Since the development in the early 1980s, atomic force microscopy (AFM) has been one of the most useful tools in the field of nano- and bio-science. AFM is capable of imaging and characterizing various materials with nanometer-scale spatial resolution under any environmental conditions including in air and liquid. My research group applied our understanding of cantilever dynamics to advance the state of art AFM by (i) interpreting the signal generated by a cantilever’s motion; (ii) designing a new cantilever system to obtain more information about material properties; and (iii) developing new (or advanced) techniques to measure multiphysical properties such as piezoelectricity and IR absorptivity. We recently invented a new AFM probe, so-called the inner-paddled cantilever, which enables two independent transduction channels to extend AFM’s capability of material characterization beyond topographic imaging. This talk will highlight the extended capabilities enabled by the new AFM probe. Our advanced capabilities of material characterization using AFM are also actively applied to bio/energy material research. This talk will introduce our recent AFM results of investigating the role of collagen piezoelectricity in bone mineralization and in-situ measurements of battery electrodes.

Dr. Hanna Cho is an Assistant Professor in the Department of Mechanical and Aerospace Engineering at The Ohio State University since 2015. Dr. Cho earned BS and MS degrees in Mechanical Engineering from Yonsei University, South Korea in 2002 and 2004, and a PhD at the University of Illinois at Urbana-Champaign (UIUC) in 2012. Cho’s research laboratory, the Micro/Nano Multiphysical Dynamics Laboratory, is focused on studying nonlinear dynamics in micro/nanomechanical systems to utilize beneficial nonlinear characteristics in developing novel Micro-Electro-Mechanical Systems (MEMS) such as sensing, imaging and energy harvesting; and multi-physical dynamics arising in atomic force microscopy (AFM) to advance state-of-the-art AFM. She is a Young Faculty Award and Director’s Fellowship recipient from Defense Advanced Research Project Agency (DARPA). ​​
