Plastic “Magic Carpet” Created – Inspired By Indian-Origin Scientist
“A miniature magic carpet made of plastic has taken flight in a laboratory at Princeton University.
The 10cm (4in) sheet of smart transparency is driven by “ripple power”; waves of electrical current driving thin pockets of air from front to rear underneath.
The prototype, described in Applied Physics Letters, moves at speeds of about a centimetre per second.
Improvements to the design could raise that to as much as a metre per second.
The device’s creator, graduate student Noah Jafferis, says he was inspired by a mathematical paper he read shortly after starting his PhD studies at Princeton…
Harvard University’s Lakshminarayanan Mahadevan, who wrote the 2007 paper in Physical Review Letters that inspired the whole project, expressed a mixture of surprise and delight at the Princeton team’s success.”
