Gecko Inspired Adhesion Enables Damage Free Handling Of Sensitive Devices #Biomimicry

Micrsopic pillars inspired by geckos allow adhesion that can be switched on and off making it easier to handle sensitive devices without damaging them. via inm-gmbh

Components with highly sensitive surfaces are used in automotive, semiconductor and display technologies as well as for complex optical lens systems. During the production process, these parts are transferred in between many process steps. Each pick-up and release with conventional gripping systems involves the risk of either contamination of the surfaces with residues from transportation adhesives, or damaging due to mechanical gripping. Suction cup systems diminish residues, but fail in a vacuum or on rough surfaces. Researchers at the INM enhanced the Gecko adhesion principle such that adhesion can be switched on and off in vacuum.
The researchers from the INM will be presenting their new Gecomer® technology at the International Nanotechnology Exhibition and Conference nano tech 2015, Tokyo, Japan.

“Artificially produced microscopic pillars, so-called gecko structures, adhere to various items. By manipulating these pillars, the adhesion can be switched off. Thus, items can be lifted and quickly released,” explains Karsten Moh from the Program Division Functional Microstructures. “This technique is particularly interesting in vacuum, as suction cups fail here,” says Moh. Parts can, for example, be handled in a deposition chamber. With the currently developed adhesion system, objects with smooth surfaces can be lifted and released, having a weight of approximately 100 grams per square centimeter (ca.1.4 lbs per square inch).” In our test runs, the system has proved successful even after 100,000 runs”, says the upscaling expert Moh.
The development group is now working on the gripping of objects with rough or curved surfaces without leaving residues. “Then, we could also move glass lenses without damaging them in the production process,” says Moh. Therefore the investigators focus their work on testing the influence of different triggers like light, magnetic field, electric field or changes in temperature.
