MULTI CHANNEL REAL TIME FEEDBACK SYSTEM BASED ON MICROCONTROLLER FOR NEURAL STIMULATION

摘要

PURPOSE: A multi-channel real-time feedback system for stimulating nerves is provided to reduce delay time from the detection of a nerve signal to the output of final electrical stimulation using a general microcontroller unit (MCU), thereby constructing cheap and small feedback system. CONSTITUTION: A multi-channel real-time feedback system (1) for stimulating nerves comprises: a micro-nerve cell chip with electrode channels to acquire an electric signal generated from cultured nerve cells; an amplification unit (20) which amplifies the electric signal acquired from the electrode of the micro-nerve cell chip; a nerve signal processing unit (30) with one or more MCUs which receive and measure the amplified electric signal and generate a new stimulation waveform based on the measured electric signal; and a switching unit (40) which selectively provides the generated stimulation waveform to the electrode channels of the micro-nerve cell chip.
