In this study the dielectric properties are reported for human skin tissues over the frequency range 1-450 MHz at 36 degrees C. Healthy volunteers, collagen disease patients and dialysis patients are studied in order to investigate, primarily, the variability among (1) different regions of one individual, (2) the same region among different individuals and (3) skin conditions due to diseases. Considerable differences exist among the skin dielectric properties obtained from different regions of one individual body. Although region dependence is observed, larger variability is found even in the same skin region among individuals.
在本研究中,报告了36摄氏度下1 - 450兆赫兹频率范围内人体皮肤组织的介电特性。研究了健康志愿者、胶原病患者和透析患者,主要目的是调查:(1)同一个体不同区域之间;(2)不同个体的相同区域之间;(3)疾病引起的皮肤状况之间的变异性。从同一个体的不同区域获得的皮肤介电特性存在显著差异。虽然观察到区域依赖性,但在个体间的同一皮肤区域中也发现了更大的变异性。
