To test the idea, the researchers measured the density of sweat pores. Because they knew that touch receptor cells cluster around sweat pores.
为了验证这一想法，研究人员又测量了志愿者指尖的汗毛孔密度，因为他们知道触觉受体细胞总是聚集在汗毛孔周围的。
Because the resistances between the remaining trace and non-remaining trace are different in paper, we can test remaining trace on paper by testing the resistance of invisible fingerprints of sweat.
由于纸张上有无残留痕迹处的阻抗不同，因此可以通过测试纸张有无汗潜指纹纹理处的阻抗，来实现检测纸张上残留痕迹的目的。
