Stretchable Electrode Could Fit the Brain

Mar-15-17 With help from a soup additive, researchers have created a plastic electrode able to stretch like rubber while still conducting electricity.

The new material, from a team at Stanford University led by Zhenan Bao, relies on a molecule similar to that used to thicken soups in commercial kitchens. When added to a conductive plastic already known to have a high conductivity and biocompatibility, the molecule served to “separate the two tightly wound polymers,” allowing the material to stretch without affecting its conductivity.

The team believes the material could have particular applications in developing brain-computer interfaces able to flex and adapt as the brain changes shape throughout the day.
