The development of implantable brain-computer interface (iIMC) technology has shifted from a purely research field to clinical applications. Despite the large number of projects on the subject under consideration, key issues such as ensuring long-term operational stability and biocompatibility remain unresolved. High risks of implant rejection and impaired brain homeostasis are still significant obstacles to the certification of such devices. Development of a prototype of a low-power eight-channel implantable brain-computer interface (iIMC) with a closed loop, equipped with wireless data transmission and wireless energy transmission systems. A scientific substantiation of the possibility of using a continuous wireless power transmission system (nBPE) with inductive coupling for iIMC operation has been carried out. The structural scheme of the iIMC has been developed. The main components of the device are described and analyzed. The evaluation of the efficiency and safety of the nBPE system based on experimental data with a model of biological tissues is presented. The concept of an iIMC with an nBPE system proposed in the work can be used to develop an implantable brain-computer interface with a new generation wireless data transmission and wireless energy transmission system that ensures user safety by minimizing the risks associated with the failure of the built-in electric power storage devices and repeated surgical interventions to replace or maintain implants.
