High Precision Temperature Measurement for Microfluidic Chip Applications
文献摘要：
Biochemical reaction in microfluidic chip is sensitive to temperature.Temperature precise control in a small size device requires the temperature measurement with high measurement precision.Traditional temper-ature measurement method usually measures the voltage drop of the thermistor,which is excited by a constant current source.This method requires the constant current source with high precision and stability.The output of the constant current source is influenced by environmental factors,resulting in a larger measurement error.To solve this problem,a proportion method,a two-layer filtering algorithm,and a power management technique were applied to improve the temperature measurement precision.The proportion method can reduce the low frequency fluctuation error.The two-layer filtering algorithm can reduce the high frequency fluctuation error further.The power management technique used can improve the system stability.Through testing the temperature measure-ment system built,the experimental results show that the fluctuation error can be significantly decreased from 0.5℃to 0.2℃.
