The Art of Magnetic Manipulation
Magnetism is capable of manipulation of objects both large and small, near and far, visible and invisible. This talk will focus on two ways in which magnetic devices are being developed for manipulation. More specifically, I will present two examples in which we are using magnetism to design extremely versatile devices with applications to haptics and communications. First, we will consider what is needed to make a reconfigurable haptic interface, one that gives the user the sensation that they are feeling what they are seeing on a visual display. True 3D fidelity in a tactile display requires extremely flexible materials that can also be programmed real-time to physically illustrate what is visually displayed on the screen. Here, I will present how our magnetic elastomer composites can be used to achieve such fidelity. The projects discussed will illustrate the impact of magnetism on the design of broadly versatile devices to ameliorate both technology and society in the future.
About Professor El-Ghazaly
Amal El-Ghazaly is an assistant professor in electrical and computer engineering at Cornell University. Her work combines magnetism, ferroelectricity, and waves to create versatile electronic systems for telecommunications, sensing and actuation. Prior to joining Cornell in 2019, she was a postdoctoral fellow at the University of California Berkeley, where she received the University of California President's Postdoctoral Fellowship in 2017. Her postdoctoral research explored ultrafast all-electrical switching of magnetic nanodots for faster computer memories. She earned a Ph.D. in 2016 in electrical engineering from Stanford University, where she was funded by both NSF and NDSEG graduate research fellowships as well as the Stanford DARE fellowship. Her Ph.D. research focused on radio frequency magnetic and magnetoelectric thin-film devices for tunable communications. She received her B.S. and M.S. degrees in electrical and computer engineering from Carnegie Mellon University in 2011.
