摘　　要：目的:研制人体脂肪自动检测仪.方法:利用高频恒定电流将人体阻抗转换成电压测量,用电阻抗和体重指数相结合的方法计算脂肪率,单片机处理和显示.结果:180例正常人脂肪率均值,男性20.4±5.7(%),女性25.7±5.1(%).结论:仪器的测量结果合理,可用于判定人体肥胖的程度.Objective:To develop the body fat ratio detector.Methods:Using high frequency and constant electric current to divert the body electric impedance into voltage and then survey.Employed the combination of electric impedance & body mass index to determine the fat ratio of the overweights,and used chip (microprocessors) to process and display.Results:Among 180 normal average fat ratio cases,we got 20.4±5.7(%) of male,and 25.7±5.1(%) of female.Conclusion:The results are reasonable with this detector and can be used to measure the body fat ratio.
