Mystery solved: The case of the slipping finger

Haptics researchers have long known that applying ultrasonic vibrations to a flat, featureless glass plate makes it feel slippery. But they have also long debated why this occurs.

Lattice structure absorbs vibrations

Researchers at ETH Zurich have developed a lattice structure capable of absorbing a wide range of vibrations while also being useful as a load-bearing component—for example, in propellers, rotors and rockets. It can absorb ...
