Researchers from the MIT developed a perovskite thin-film material whose electrical properties can be switched between metallic and semiconducting, simply by applying a small voltage. The material then stays in its new configuration until switched back by another voltage.

This type of material could lead to a new memristor design as it can retain information when the power is switched off. This is still an early-stage development, but one that we should keep an eye on.
