The planes have light skeleton to reduce weight and streamline shape to reduce drag during flight. Better aerodynamic helps the plane to be more fuel efficient.]]> 2022-05-21 15:00:27 UTC https://padlet.com/wong19991008/Bookmarks/wish/2193965789 wong19991008 https://padlet.com/wong19991008/Bookmarks/wish/2193982364 Microneedles are inspired by the mosquito's ability to pierce the skin painlessly with its proboscis. In contrast to hypodermic needles, microneedles only penetrates the dermis layer and is able to draw blood or deliver drug while minimizing the pain during the process.]]> 2022-05-21 15:28:04 UTC https://padlet.com/wong19991008/Bookmarks/wish/2193982364 wong19991008 https://padlet.com/wong19991008/Bookmarks/wish/2193987240 The design of bullet train was inspired by the king fisher bird. Bullet train used to create a loud sound called tunnel boom when it exits a tunnel because of the air pressure building up in the tunnel and then released. However, the problem was solved when the head of the train was redesigned to mimic the kingfisher's sharp beak. The new design not only solves the problem, but also makes the train faster while using less electricity.]]> 2022-05-21 15:35:27 UTC https://padlet.com/wong19991008/Bookmarks/wish/2193987240 wong19991008 https://padlet.com/wong19991008/Bookmarks/wish/2193992250 Self cleaning materials imitate the ultrahydrophobicity of lotus leaf known as the lotus effect. This characteristic allows dirt particles to be picked up by water droplets due to microscopic architecture on the surface that minimizes the droplet's adhesion to the surface, therefore achieving the "self cleaning" effect. The use of this technology helps to reduce the energy and resources needed for cleaning.]]> 2022-05-21 15:43:33 UTC https://padlet.com/wong19991008/Bookmarks/wish/2193992250 wong19991008 https://padlet.com/wong19991008/Bookmarks/wish/2193994477 Solar panels mimic the photosynthetic ability of plants by converting sunlight into usable energy. They convert sunlight into electrical energy with photovoltaic panels or mirrors that concentrate solar radiations. Solar panels do not produce any emissions and pollution, therefore they are a sustainable source of energy.]]> 2022-05-21 15:46:49 UTC https://padlet.com/wong19991008/Bookmarks/wish/2193994477 wong19991008 https://padlet.com/wong19991008/Bookmarks/wish/2209694422 Some animals have the ability to change the color of their body according to the surroundings to hide themselves from predators or sneak up on prey. Military camouflage uniforms use this principle to blend in with the environment. It allows soldiers to hide in plain sight and difficult to be detected by enemies. ]]> 2022-06-03 02:37:23 UTC https://padlet.com/wong19991008/Bookmarks/wish/2209694422 wong19991008 https://padlet.com/wong19991008/Bookmarks/wish/2209767043 The invention of Velcro hook-and-loop fastener was inspired by burrs. A burr is the seed or fruit of a plant that has tiny hooks on it and clings to fabric or fur. Velcro uses this feature to stick to the loop with its hook. This adhesive characteristic is completely chemical free and does not produce any pollutants.]]> 2022-06-03 04:10:32 UTC https://padlet.com/wong19991008/Bookmarks/wish/2209767043
