Biomimicry breakthroughs




Phonology in progress

Le suffixe -ion et ses dérivés

Lorsqu’on ajoute le suffixe -ion à un mot, l’accent tonique se place sur la syllabe avant -ion.

Ex : refrigerate /rɪˈfrɪdʒəˌrεɪt/refrigeration /rɪˌfrɪdʒəˈrεɪʃən/, transporttransportation, accumulateaccumulation

“Biomimicry: How Nature Solves Problems”, David Camacho, Inherit the Earth, 2018.

Michael Pawlyn, a British architect noted for his work in the field of biomimetic architecture, thinks that through biomimicry we can radically increase our resource usage efficiency. Following his lead, let’s take a look at some examples of how biomimicry has been applied in the real world:

Heat resistant vaccines: Tardigrades (micro-animals) can dry out for up to 120 years and then come back to life. They fully dehydrate when the environmental conditions are adverse, by entering into a standby process that protects the physical and chemical structures of their bodies. By studying this, the company Biomatrica created a product that maintains live vaccines without the need for refrigeration.

Shinkansen Bullet Train: one of the fastest trains in the world – it is able to travel up to 320 km/h. Unfortunately, because of the air pressure accumulation, the vehicle used to cause a great sonic boom each time it emerged from a tunnel. The imminent solution was later found in the kingfisher bird, an animal that is able to dive into water producing almost no splash at all. By simulating the bird form in the front of the train, the shotgun-like sound was solved, and not only this, the efficiency of the train was improved – 15% less energy use and 10% greater speed.

Blades and whales: Humpback whales are usually characterized by their size and great agility. The bumps or tubercles on the edge of their fins are one of the reasons these animals are so quick in the water. Inspired by this, Frank Fish, an appropriately named biology professor at Westchester University in Pennsylvania, added similar bumps to turbine blades and obtained great results: increased speed, reduction of noise and a boost of air power up to 20%.

Painless needles: have you ever noticed how the mosquito is able to suck blood without causing any pain? Well, a painless needle that mimics the mosquito has been built by Suman Chakraborty of the Indian Institute of Technology in Kharagpur and Kazuyoshi Tsuchiya of Tokai University in Kanagawa. The needle will be able to draw blood, inject drugs, and to check glucose level on diabetic patients.

Velcro: after going on a walk, George de Mestral, a Swiss engineer, realised how many burdock seeds had clung to his coat and to his dog fur. Inspired by this, he studied the seed structure and mechanism, imitated it and created velcro.
