According tomedia reports, geckos have been important research objects. Because its feet have a natural adhesion, this allows it to hold almost any surface. Although researchers have been able to mimic the stickiness of geckos, which use rubber bars to grab and release objects, mass production has not been possible.
Now, researchers from the Georgia Institute of Technology have developed a new way to make gecko-inspired bonding materials that are more cost-effective than current methods. The new discovery will make mass production possible and introduce gecko-based adhesive strips into manufacturing and consumers. The polymer is made from a gecko’s attached surface, the researchers said, which can be used to make a wide range of pliers that can clamp objects on the same assembly line.
In addition, this adhesive material can also make hanging pictures easier. Scientists also believe that one day, gecko robots could replace humans cleaning up the facades of high-rise buildings. Researcher Michael Varenverg points out that the gecko adhesive can stick to anything but teflon.
The researchers say the use of gecko attachment and manufactured grabbers has a clear advantage — no need to prepare for a specific surface before being able to grab a target. This adhesive places flat objects such as boxes on the same line as surface objects such as eggs and vegetables. Currently, grabbers on the assembly line use items such as clips, magnets and suction cups, but can only grab a limited range of objects.
In addition, the gecko-inspired gripper is dry, free of glue or sticky material, and can replace many grabbers while filling the capacity gaps left by other grabbers. The material is made by pouring the ingredients onto the template, allowing the mixture to react to form a flexible polymer, and then removing it from the mold. The new method created by the researchers is to pour the material onto a smooth surface, rather than to create the corresponding shape in a set of molds. Unfortunately, there is no indication of a timetable for the commercialization of such materials.
