Shape-Shifting Materials for Programmable Structures
In this paper we discuss how the jamming phenomenon of granular materials might be exploited to achieve programmable matter – a robotic material that permits user specified shape changes. Opportunities for applying this research to the field of architecture are discussed. Experimental results are presented, which reveal the performance of a wide variety of materials under jamming conditions.
متن کاملShape-Shifting Droplet Networks.
We consider a three-dimensional network of aqueous droplets joined by single lipid bilayers to form a cohesive, tissuelike material. The droplets in these networks can be programed to have distinct osmolarities so that osmotic gradients generate internal stresses via local fluid flows to cause the network to change shape. We discover, using molecular dynamics simulations, a reversible folding-u...

mechanism of oceanic control of climate. They constitute a repository for heat, fresh water and gases such as carbon dioxide, all of which are exchanged at the ocean–atmosphere interface.On the largest scale, the water masses spread and fill the ocean basins. These huge bodies of water are also the engines of large-scale ocean circulation, one that is primarily driven by so-called North Atlanti...
متن کاملEarly shape-shifting FRET probe.
I am gratified by the positive response to my recent review article (1), especially when it comes from the scientific group that made very significant contributions to the field of fluorescence resonance energy transfer probes. The papers mentioned in the letter are important and were not cited in the review because they were published after the final version of the review had already been subm...
متن کاملShape Change Through Programmable Stiffness
We present a composite material with embedded sensing and actuation that can perform permanent shape changes by temporarily varying its stiffness and applying an external moment. Varying stiffness is a complementary approach to actuator-chain based approaches that can be accomplished using a large variety of means ranging from heat, electric field or vacuum. A polycaprolactone (PCL) bar provide...
