This week on Engineering Newswire, brought to you by Mouser Electronics, the electronic components distributor with the widest selection of the newest products, we’re digging ditches with Big Bertha, using self-cleaning super glass, making a mini Mona, and electrifying hydrogels to make soft robots. This episode features:

  • Researchers at North Carolina State University have further developed soft-robotics research by using hydrogels – a polymer substance that is almost entirely water.
  • The SR 99 tunneling machine, also known as Bertha, has started her two-mile journey through downtown Seattle with her 5 story-tall cutter-head.
  • Researchers at the Georgia Institute of Technology have "painted" the Mona Lisa on a substrate surface about 30 microns in width – that is one-third the width of an average human hair.
  • A team from the Wyss Institute for Biologically Inspired Engineering at Harvard University has reported a new transparent, bioinspired coating that makes ordinary glass tough, self-cleaning, and incredibly slippery.
