Great and exciting innovation from MicroTau, the company that is trying to “solve human problems with natures surfaces”. MicroTau, an advanced manufacturing company utilises nature's already existing unique and practical surfaces to be able to directly print biomimetic patterns to surfaces, think anti-reflective moth eyes for example. Their microfabrication has been utilised so far in industries such as aviation, shipping, healthcare and aerospace. By mimicking low-drag shark skin "riblets" in microfabrication the company has been able to exhibit a 7% drag reduction and combat fuel burn for the US Airforce.
