Selection and biocompatibility of electrode in spinal cord stimulator system

The spinal cord stimulator (SCS) is a highly effective technology for treating neurological illnesses. It is mainly composed of a pulse generator and electrode. The electrode selection is crucial because it ensures not only the proper transmission of stimulation but also the safety of the human body. This paper primarily introduces the current market electrodes, their benefits, drawbacks, and future development directions, as well as potential difficulties and biocompatibility. This paper intends to provide readers with a more thorough understanding of SCS electrodes and their problems, so that they may make more informed decisions about SCS electrode development in the future.
