85‐3: <i>Invited Paper:</i> Magnetically, Vertically‐Aligned Conducting Ferromagnetic Particles for Electrical and Heat Conduction in Stretchable Electronics

My group spent several years to develop sensor and bonding materials based on composites with conducting ferromagnetic particles for flexible/stretchable display and soft electronic skin applications. Vertically aligned conductive particles provides excellent electrical conducting paths without electrical short in lateral direction up to 10 micro meter scale and pressure sensitive resistive paths up to 100 dpi resolution even without lateral patterning. In addition, such composites can be used for temperature sensing material because they change in their physical dimensions with temperature, leading to resistance change with temperature. In this invited talk, my group's most recent result in micro scale display integration and high‐ resolution sensor implementation based on the composite material that we developed.
