Antibacterial Power of Black Silicon

Antibacterial Power of Black Silicon | Biomimicry | Scoop.it

"Earlier this year, we reported about a finding which revealed that physical structure of Psaltoda claripenniscicada wings can shred certain types of rod-shaped bacteria. After analyzing the surface, researchers at the Swinburne University of Technology used biomimicry to create a surface with similar properties. This nanosurface could lead to development of a new generation of nanostructured antibacterial materials. 

“Based on this discovery, we investigated other insects that may possess similar surface architectures that might kill more bacteria, in particular the deadly strains of the Staphylococcus aureus or golden staph bacterium”, said Elena Ivanova, microbiology professor at the Swinburne University of Technology. Their search led them to the wings of the Diplacodes bipunctata (Wandering Percher dragonfly), whose spike-like nanostructure destroys both rod-shaped and spherical bacteria."

BionicOpter Dragonfly Drone Flutters About, Blows Minds

BionicOpter Dragonfly Drone Flutters About, Blows Minds | Biomimicry | Scoop.it

"After crafting a machine last year that soared around like a herring gull, now the company [Festo] has created BionicOpter. The 17.3-inch long dragonfly drone can flutter through the air in any direction, and even hover, just like its biological inspiration. Its four carbon fiber and foil wings beat up to 20 times per-second, propelling it through the air as if it were swimming rather than flying."

Revamped Wind Turbine Takes Design Inspiration From Dragonflies

Revamped Wind Turbine Takes Design Inspiration From Dragonflies | Biomimicry | Scoop.it

"When compared to traditional turbines, the Dragonfly Invisible Wind Turbine can withstand stronger winds, and is capable of functioning in low-intensity winds. The technique lies in the slim-line design of the turbines, which is developed to mimic the form of a dragonfly in flight and how it can glide through gale-force winds."
