Summer nature inspires inventors
Summer is the perfect time to innovate! Did you know that some of the most innovative solutions in technology and design are inspired by summer nature? After all, plants and animals have qualities that beat even the most inventive minds of engineers.
Biomimetics is a field of research that seeks to solve practical problems by modelling structures, functions and materials found in nature. Here are a few examples of how nature's masterpieces have found their way into innovations.
Inspiration for solar panels from butterfly wings
Nanostructure mimicking butterfly wings reduces the reflectivity of solar panels, allowing the panel to produce more energy. Marko Huttula at the University of Oulu is researching the topic.
An uncoated panel reflects 35 % of the light that hits it. A nanostructure imitating butterfly wings would reduce the reflection to 5 %. In Huttula's study, the reduction in reflection led to a 66 % increase in the maximum current that the cell could deliver.
Burdock burrs inspired Velcro
Anyone who has removed burdock burrs from their clothes knows how tightly they stick. Swiss engineer Georges de Mestral wondered the same thing when he removed burdock burrs from his clothes. It was these little nuisances that gave him the idea: a Velcro strip with one side full of tiny hooks and the other with a fluffy gripping surface. Velcro is now commonly used, for example, in textiles.
The structure of the hedgehog's spines revolutionises the impact resistance of helmets
The structure of hedgehog spines and their ability to absorb shocks is revolutionising the impact resistance of helmets. The materials and structures inspired by these spikes offer better protection in helmets for cycling and motorbike helmets, for example.
Blue mussel protein straps and wound care
The strong and flexible structure of mussel protein bands has provided a model for new medical adhesives that can be used to treat surgical wounds. These materials improve wound healing and reduce complications.
Thermite mound’s cooling system inspires architecture
The ingenious design of termite mounds keeps their interiors cool even when it is scorching hot outside. This passive cooling system has inspired architects to design energy-efficient buildings that stay cool without air conditioning.
The lotus effect
Lotus leaves are known for their ability to repel water and dirt. This property has inspired the development of self-cleaning surfaces and materials that can be used in applications such as windows and vehicle coatings.
Why reinvent the wheel when you can take a cue from nature? Nature is full of innovations that can improve our quality of life and solve complex problems. So next time you're enjoying a summer day outdoors, look around — you might just find inspiration for your next invention!
