Slug mucus sticks well to wet tissues, which appeals to surgeons. David J. Mooney of Harvard University made a glue similar to slug snot, and "tested the adhesive on pig skin, liver, heart, and cartilage and found that it was stronger than both cyanoacrylate (superglue) and a surgical sealant called CoSeal," reports Chemical and Engineering News.
Mooney and his colleagues came across a paper analyzing the material properties of mucus from a type of slug (Arion subfuscus). The sticky mucus has two components: polycations that help the mucus adhere to surfaces through electrostatic interactions and covalent bonding, and a tough matrix that absorbs and dissipates stress. This combination allows the slug to stick strongly to a surface by resisting forces—such as those from wind, rain, or the beak of a hungry bird—that could dislodge it.
Biomimicry continues to make amazing strides. Festo just released footage of their OctopusGripper being put through the paces.
Poking a golden tortoise beetle (“goldbug”) triggers the insect’s color to change from gold to a red-orange. Inspired by the natural system underlying that insectoid superpower, MIT researchers have developed flexible sensors circuits that can be 3-D printed. Eventually, the technology could lead to sensor-laden skin for robots. From MIT News: “In nature, networks of […]
A team of roboticists from Caltech and Urbana-Champaign have built a biomimetic “bat bot” that uses nine joints to deform a foot-wide wing membrane to achieve breathtaking aerial maneuvers.
