This paper, on the basis of the electrostatic discharge test of mobile user terminals and electrostatic parameters measurement of human body, got electrostatic potential of human body in different condition. The results show that the main factors effecting human body electrostatic are environmental relative humidity, humans dressing, human activities and so on. Then error between the experimental measurement data and the theoretical analysis result are analyzed. Finally proposed some protective measures according to the harm of human body electrostatic to mobile user terminal.
