Shape-memory metals, which can revert from one shape to a different one simply by being warmed or otherwise triggered, have been useful in a variety of applications, as actuators that can control the ...

Combining materials with different swelling ratios creates structures that transform into tubes when exposed to water. (Courtesy: Yu Bin Lee) Materials that controllably change shape over time – often ...

Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG)Aug 9 2024 A key question that remains in biology and biophysics is how three-dimensional tissue shapes emerge during animal ...

New cell-laden bioink, comprised of tightly-packed, flake-shaped microgels and living cells, the production of cell-rich 4D bioconstructs that can change shape under physiological conditions. Where ...

Engineers have created shape-memory materials made of ceramic rather than of traditional metal. The development opens a new range of applications, especially for actuators in high-temperature settings ...
