A pocket-sized illusion runner done of cosmetic has taken flight in a laboratory at Princeton University.
The 10cm (4in) piece of chic clarity is driven by "ripple power"; waves of electrical stream pushing gaunt pockets of air from front to back underneath.
The prototype, described in Applied Physics Letters , moves at speeds of about a centimetre per second.
Improvements to the pattern could elevate that to as sufficient as a metre per second.
The device's creator, connoisseur tyro Noah Jafferis, says he was desirous by a arithmetic paper he read before long after starting his PhD studies at Princeton.
He deserted what would have been a select plan copy electronic circuits with nano-inks for a that seemed to have more in common with 1001 Nights than 21st-Century engineering.
Prof James Sturm, who leads Mr Jafferis' investigate group, conceded that at times the plan seemed foolhardy.
"What was tough was determining the correct poise of the piece as it misshapen at high frequencies," he told the BBC.
"Without the skill to envision the expect way it would flex, you couldn't feed in the right electrical currents to obtain the thrust to work properly."
What followed was a two year digression attaching sensors to every segment of the element so as to fine-tune its opening by a array of intricate feedbacks.
But once that was mastered, the waveform of the undulating suited that prescribed by the theory, and the wafting motions gave life to the minuscule carpet.
In the paper describing the design, Mr Jafferis and his co-authors are clever to keep the word "flying" in inverted commas, since the consequent appurtenance has more in common with a hovercraft than an aeroplane.
"It has to keep shut to the ground," Mr Jafferis explained to the BBC's Science in Action, "because the air is then trapped between the piece and the ground. As the waves pierce along the piece it essentially pumps the air out the back." That is the source of the thrust.
Harvard University's Lakshminarayanan Mahadevan, who wrote the 2007 paper in Physical Review Letters that desirous the entire project, voiced a combination of astonishment and pleasure at the Princeton team's success.
"Noah has vanished over the elementary theory and obviously built a device that works," he told the BBC "And what's more, it behaves, at least qualitatively, as you had predicted."
Mr Jafferis points out that the antecedent is paltry since minuscule conducting threads anchor it to complicated batteries, so it's giveaway to pierce usually a couple of centimetres. But he is already working on a solar-powered ascent that could openly fly over considerable distances.
The value of this type of propulsion, he argues, is that different jets, propellers and hovercraft, there are no relocating components similar to cogs and gears that massage against any other.
"The preferred use would be a few type of dusty, soiled mood where relocating tools would obtain gummed up and stop," he explained.
That said, he laughingly admits that with the existing materials, a drifting runner absolute enough to bring a person would need a wingspan of 50 metres - not the most appropriate van to take on the streets just yet.
On the other hand, rough calculations indicate that there is enough sky on the world Mars to send buoyant rovers scudding over its dry surface.
Meanwhile, Prof Mahadevan looks deliver to sophisticated improvements in the nearby future, suggesting the draw close could growth to "mimicking the pleasing two-dimensional undulations of the movement or manta ray".
