A new ‘super-hydrophobic’ surface developed by researchers at Rochester University’s Institute Of Optics that makes water bounce off as if repelled by a magnetic force.

Unlike previous temporarily water-repelling surfaces (like Teflon), this permanently hydrophobic material consists of metal into whose surface microscopic structures are etched with lasers.

Possible applications include waterless toilets, rustproofing and airplane wings that repel ice.

The Aposematic jacket, according to its creator Shinseungback Kimyonghun is a:

‘wearable camera for self-defense. The lenses on the jacket give off the warning signal, “I can record you”, to prevent possible attack. When the wearer pushes a button under threat, the jacket records the scene in 360 degrees and sends the images to the Web.’

Subtle.
