<p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 12pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">Magnetism is often overlooked
except to show that “opposites attract.” Yet, compared to electric fields, magnetic fields are often capable of greater manipulation of objects both large and small, near and far, visible and invisible.
</span><span style="font-family: Arial; font-size: 12pt; white-space: pre-wrap;">This talk focuses on the development of haptic (tactile) displays using magnetism. First, El-Ghazaly considers 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, she presents how their magnetic elastomer composites can be used to achieve such fidelity.
</span><span style="font-family: Arial; font-size: 12pt; white-space: pre-wrap;">The research involves two key approaches for developing and enhancing magnetic elastomers for tactile manipulation. The first is the development of ultraflexible, thin-film magnetic
elastomer materials formed using nanoscale magnetic particles. The second is the synthesis of very high remanent moment magnetic nanoparticles for inclusion in the elastomer material. With the goal of integrating haptic displays with widespread touch screen
technology, this project illustrates the potential impact of magnetism on providing versatility to these ubiquitous systems and ameliorating user interactions with such technologies in the future.</span></p>
