Cambridge, Massachusetts–based Axoft designed its novel Fleuron material for use in implantable brain-computer interfaces (iBCIs). Fleuron, which is 10,000 times softer than the polyimide material used in existing iBCIs, the company says, offering superior biocompatibility while reducing tissue scarring and lead migration over time.

Fleuron resembles a rubber-like version of Teflon, offering longitudinal stability as a thin-film material.
