New type of conductive bioplastics has been fashioned by a young researcher, that is to boost the performance of bionic devices, electronic devices and mechanical parts that assist humans in performing difficult, dangerous, or intricate tasks, such as the cochlear ear and the proposed bionic eye. Rylie Green, Biomedical Engineer, University of New South Wales (UNSW) explained that this plastic will enable reach to smaller devices that utilise safer smaller currents and encourage nerve interactions. At present, the electrodes they use are made from metals such as platinum and iridium.
Conductive plastics or polymers are an alternative to metals. They have rough surfaces which encourage the attachment of cells, meaning they offer potential for improved performance and longevity when implanted in the body as electrodes. Additionally, the highly textured polymer surface can pass electrical current to cells more efficiently than smooth metals.
