摘要：
Water content detection is important for our daily life. For environmental detection, the relative humidity is an index for comfortable living atmosphere. For skin health, the water content in stratum corneum is a parameter to diagnose the skin condition. This paper mainly describes a moisture sensor for determination of human skin moisture. The skin moisture sensor is based on the conventional humidity sensor structure (interdigital capacitance, IDC), and the moisture sensor is also sensitive to the environmental humidity. Therefore, the effects of the environment, temperature and humidity, are discussed to find the appropriate operation conditions for skin moisture detection. Besides, the application of the moisture sensor for the environment detection is also described. The IDC structure is fabricated by using printed circuit board (PCB) technology which simplifies the bonding technique and reduces the cost. (C) 2008 Elsevier B.V. All rights reserved.
