Robots aren’t always the most delicate of machines when handling fragile objects. They don’t have the lightness of touch of humans. But that could be about to change thanks to a new development in smart materials.

Researchers have developed a method for weaving flexible fibers that can be controlled by magnetic fields. Not only can this be used for robot hands to pick up objects like soft fruits, potato chips and worms, but it can also be used in a range of other applications. These include gloves that provide a realistic touch in virtual reality and breathable fabrics.
