Modern meat cell impedance spectroscopy is a new technology in meat cell activity detection.In this paper,based on the analysis of pork cell tissue,the pork cell impedance spectrum detection electrode was designed and simulated,and the electrode was made by lithography technology.The cell impedance spectrum was tested by inputting different frequencies of excitation to the electrode,and a rapid pork cell freshness detection system was constructed by analyzing the correlation between impedance spectrum and pork storage time.At the same time,in order to increase the practicability of the portable pork cell detection equipment,the information about the internal reaction of the battery was extracted from the battery electrochemical impedance spectroscopy of the portable equipment based on EIS technology,the relationship between impedance and frequency was analyzed,and various performance parameters of the battery were revealed for battery optimization.
