Team of researchers devise new method for stacking microscopic marbles to produce wearables

a. Bend Induced Oscillation Shearing

b. Bend Induced Oscillatory Sharing

c. Bend Induced Oscillatory Shearing

d. None of the above

 

A team of researchers devised a new method for stacking microscopic marbles into regular layers which produce intriguing materials scattering light into intense colours and which change colour when twisted or stretched.

• Team led by University of Cambridge used a new method called Bend Induced Oscillatory Shearing to produce hundreds of metres of material called “polymer opals” on roll-to-roll process
• Results have allowed sheets to be manufactured on industrial scale, opening up apps from smart clothing for people or buildings to banknote security.
• The brightest colours in nature can be found in opal gemstones, butterfly wings and beetles. Materials get their colour from the systematically ordered microstructures contained
• When stretched, the material shifts into the blue range of the spectrum and red when compressed. The material returns to original colour on release.
