Shape-shifting materials: Extreme deformation of particle rafts

Written by

Professor Ho-Young Kim has built and modelled particle rafts and soft materials using electronic fields which could be used in soft robotics or biomedicine

How can we bend matter to our will? Folding patterns, as employed in origami, imply severely limited shape-shifting possibilities. These soft materials also need to have the right shape-morphing properties to be useful for their desired application. Professor Ho-Young Kim at Seoul National University has been building and modelling particle rafts – new soft composite interfaces with superior deformability, that […]

Moisture regulation in finger pad ridges can ensure optimal grip

Written by

The ridges on the pads of our fingers, and the fingerprints we produce, have several benefits, including identification purposes. However, this was not the evolutionary purpose of ridged skin on the finger pad, and it is more likely to have evolved to optimise grip and touch. Professor Gun-Sik Park, Seoul National University, has explored how the finger pad has its […]
