http://www.mdpi.com/journal/micromachines/special_issues/biomimetic/ Dear Colleagues, The natural world has come to its today’s shape through countless processes of evolution, failure and success determining the very existence of organisms. Nature provides us with a collection of highly functional and adequate solutions to problems organisms have solved. Biomimetics is the activity of investigating nature, getting inspired by it and mimicking certain solutions in an engineering context. Micromachining technology allows mimicking a rich natural world at a scale that is easily observable in our daily lives, yet does not stop to surprise us; water-striders walking on water, flight of flapping wing insects, the mechanics of the mammalian cochlea, object localization by scorpions, or flow sensing using hairs as seen on many arthropods, are just a few examples. Micromachining technology enables the fabrication of features on sub-micron to millimeter scales, it facilitates surface structuring effectively changing interaction with particles and fluids (think of the Lotus effect) and its batchwise fabrication allows for easy fabrication of array structures, as often found in nature, e.g., for sensing and actuation purposes. In short, micromachining allows for mimicking nature on a scale hardly feasible, if at all, by other technologies. For this reason, Micromachines has dedicated this special "Biomimetics Systems" issue to ideas, designs, devices and technology at the microscale that have been inspired by nature.
