摘　　要：将生理参数测量功能嵌入到手机等移动设备是移动健康的发展趋势。该文研究了皮肤水分和人体脂肪含量两种生理参数的测量方法,设计了可贴在手机表面的、方便嵌入手机的测量电极。数据处理方面,实验探索方便快速的测量方法,皮肤水份和全身体脂测量结果,与商用产品相比,均方误差小于4%,相关性高达0.9以上。此外,局部体脂测量表明,局部体脂含量与局部体阻抗间有接近线性的正相关关系。Integrating physiological parameters measurement into mobile devices is a development tendency of mobile healthcare. Measurement methods for skin moisture and body fat content are studied in this paper. Electrodes are designed for easy integration into mobile devices, and can be embedded in the cover of the mobile phone. Experiments were conducted to obtain a fast and easy measurement method. The results of evaluation show that the measurement system can achieve the same accuracy as commercial products （with correlation above 0.9 and root mean squared error below 4%） in skin moisture and body fat content measurement. Measurement of local-area body fat content showed a nearly linear positive correlation between local-area body fat content and local-area body impedance.
