项目摘要

The water content in the stratum corneum could be one index to evaluate the skin health, we have developed a microsensor and a small measurement system, and discuss the influence to skin from the environment of daily living conditions. The dimensions of the sensor which we developed is 5mmX5mm and a gap of about 15 μm between two electrode strips, This distance of electrodes is significantly smaller compared to conventional skin impedance measuring systems, If the film side of the sensor chip is pressed onto human skin, the change of capacitance can be used as a measure for the water content of the skin. We also developed another type sensors which had protection membrane and fine connection. We developed a new measurement method. It gives different frequences current and measure the electric characteristic each of frequences, we made new parameter to know the water content to check the relation between frequences and measured data. Finaly, we developed the small portable electric circuit and connected to a computer to realize a new measurment method. We compare measuring results on normal skin, atopic (dry) skin and skin moisturized by a humectant, we got good results. We. totally developed microsensor system for water content and established basic technology to measure skin functions.

角膜层中的水含量可能是评估皮肤健康的一种指数，我们开发了一个微传感器和一个小的测量系统，并从日常生活条件的环境中讨论对皮肤的影响。我们开发的传感器的尺寸为5mmx5mm，在两个电极条之间的间隙约为15μm，与传统的皮肤阻抗测量系统相比，电极的这种距离要小得多，如果将传感器芯片的膜侧按下人类皮肤，则可以将动力的变化用于皮肤的水含量。我们还开发了另一个具有保护膜和良好连接的传感器。我们开发了一种新的测量方法。它给出了不同的频率电流并测量每个频率的电特性，我们制作了新的参数，以了解水含量以检查频率和测量数据之间的关系。最后，我们开发了小型便携式电路，并连接到计算机以实现一种新的测量方法。我们比较了对正常皮肤，特应性（干燥）皮肤和皮肤的测量结果，我们得到了良好的效果。我们。完全开发了用于水含量的微传感器系统，并建立了基本技术来测量皮肤功能。
