Abstract
An implantable flexible electrode includes an implantation assembly and a proximal contact part. The implantation assembly is made of a flexible material, and includes an auxiliary implantation part, a microelectrode part, a macroelectrode part, and a lead part electrically connected to the microelectrode part and the macroelectrode part, a macroelectrode site of the macroelectrode part is used to record local field potential information after implantation, a microelectrode site of the microelectrode part is used to record single-unit action potential information, and the dimension of an end of the microelectrode part distal to the macroelectrode part is smaller than the dimension of an end of the microelectrode part proximal to the macroelectrode part. The proximal contact part is electrically connected to the lead part. The implantable flexible electrode enables simultaneous recording of local field potential information and single-unit action potential information to provide comprehensive information about neural activity.
