Configuration, trends, and applications of wireless epicortical and intracortical neuronal recording systems. (IMAGE)
Caption
A typical configuration of wireless neuronal recording systems consists of five modules: (1) implantable electrodes for neural signal acquisition; (2) processing chips and controller for signal amplification, filtering, multiplexing, digitization, and controlling the parameter setting; (3) wireless data transmission to computers or other portable equipment for further data analysis; (4) power supply by wireless charging or inductive coil for system power consumption; (5) package for ultracompact size and long service life. The wireless neuronal recording system is rapidly developing towards miniaturization, integration, and intelligence, benefiting from the micro-electromechanical systems (MEMS), integrated circuits (IC), wireless transmission and powering, and machine learning algorithms. It can not only be applied to healthcare and interaction for people with severe motor impairment, but also has the potential on entertainment and military scenarios in the future.
