From artificial limbs to cochlear implants, biomedical advancements are opening up new opportunities for health care. Now, researchers from the University of Delaware are working to further improve the lifetime and effectiveness of those biomedical devices by improving communication between the technology and neural tissue.
In order to improve the devices, researchers worked to develop a direct interfacing material to improve communication between the device and the body. For this, the team focused on a conjugated polymer known as PEDOT.

Compared to other methods, surface modification through electro-grafting takes just minutes. Another advantage is that a variety of materials can be used as the conducting substrate, including gold, platinum, glassy carbon, stainless steel, nickel, silicon, and metal oxides.
“Our results suggest that this is an effective means to selectively modify microelectrodes with highly adherent and highly conductive polymer coatings as direct neural interfaces,” says David Martin, lead researcher.
