我们提出了一种电容型柔性微传感器，用于测量人体皮肤竖毛引起的突然情绪和环境变化。由于皮肤体积大、重量重，现有的皮肤毛发监测方法只能通过对皮肤的物理扰动刺激来进行客观、定量的测量。所提出的柔性皮肤竖毛监测传感器由3×3螺旋共面电容器阵列组成，该电容器阵列使用导电聚合物，具有高电容密度和足够薄的厚度以附着于人体皮肤。以人体皮肤鸡皮疙瘩为模型，对皮肤竖毛监测传感器的性能进行了表征，在0~326μm范围内，对人体皮肤鸡皮疙瘩形变的灵敏度为-0.00252%/μm，非线性为25.9%.我们还验证了在受试者的前臂背侧连续两次持续时间为3.5s的人体皮肤竖毛，从而导致对于145μm和194μm的竖毛强度的电容变化分别为-6.2fF和-9.2fF。
We present a capacitive-type flexible micro sensor for measurement of the human skin piloerection arisen from sudden emotional and environmental change. The present skin piloerction monitoring methods are limited in objective and quantitative measurement by physical disturbance stimulation to the skin due to its bulky size and heavy weight. The proposed flexible skin piloerection monitoring sensor is composed of 3×3 spiral coplanar capacitor array using conductive polymer for having high capacitive density and thin enough thickness to be attached to human skin. The performance of the skin piloerection monitoring sensor is characterized using the artificial bump, representing human skin goosebump; thus, resulting in the sensitivity of -0.00252%/μm and the nonlinearity of 25.9% for the artificial goosebump deformation in the range of 0~326μm. We also verified two successive human skin piloerection having 3.5s duration on the subject's dorsal forearms, thus resulting in the capacitance change of -6.2fF and -9.2fF for the piloerection intensity of 145μm and 194μm, respectively.
