Electronic mustache help you become a cat
Mustache – it is the most natural biological sensors that help to overcome the problem of poor eyesight and hunt at night. The ability to capture even the slightest breath of wind, cats whiskers provide excellent navigation in the dark, and allow insects orient themselves in space.
Given the recent developments in biomimicry , a question only time left is when scientists equip robots with artificial mustache and provide them with similar sensory power. Dzheyvi Ali, associate professor of electrical engineering and computer science at Caltech, Berkeley, pulled it off. Robotic whiskers Dzheyvi appeared in an article in the journal PNAS January 21.
Electronic use a thin mustache nanomaterials instead of hair follicles and nerve endings replace electronic additions. But Dzheyvi claims that his creation is almost identical to the biological counterpart.
“Sensing mechanism is different, but the functionality is very similar,” – he says. ”
To create a common electronic mustache Dzheyvi and his team searched for nanomaterials that are both light and sensitive to deformation. Carbon nanotubes mustache lent its flexibility, and increased sensitivity of the silver particles. Determine the desired proportion of carbon and silver, the team introduced electronic Dzheyvi mustache capable of performing certain actions and deal with specific tasks.
“Especially impressive is that the sensitivity can be adjusted,” – says Mitra Hartmann, associate professor of biomedical and mechanical engineering at Northwestern University. ”
From underwater drones to a reasonable ground bots – Hartmann suspects that artificial mustache find themselves in a huge range of potential applications for robots .
“These whiskers can be used to simulate the” lateral line “fish to increase the stability and maneuverability of underwater vehicles,” – she says. – “, Or may be used as a direct tactile sensors, like the one used as rodents to determine their characteristics whiskers environment.”
Artificial mustache inexpensive and simple to manufacture, says Dzheyvi, so the next step will be the integration of these sensors into more complex systems. Ultimately, researchers will be able to include electronic mustache light wearable sensors capable to fix the slightest movement of the muscles and even pulse.
“Electronic mustache could be part of a robotic arm with a new level of sensitivity,” – says Dzheyvi.
