Advances in robotic, electronic, and computer technologies have changed not just our daily life but also biomedical prostheses. Human intention can be delivered to operate artificial prosthetic devices as commanding signals through so called ‘brain-machine interfaces (BMIs)’ or ‘peripheral nerve interfaces (PNIs)’. The PNI designs vary from less invasive cuff electrodes, to higher selective intraneural electrodes, and to regenerative electrodes. Challenges of the current PNIs, however, are forming chronically functional biotic-abiotic interfaces because their electrode components are mainly composed of hard materials such as metals and ceramics. To prevent the functional failures, wide ranges of soft conducting materials such as conducting polymers, conducting hydrogels, carbon nanotubes, graphenes, and natural polymers are tried. I will discuss the pros and cons of these new materials and briefly introduce our recent efforts to develop chronically implantable PNIs. |
