is primarily amorphous carbon. This research also incorporated a high-precision, rapid-responding, full-range, relative humidity micro sensor (Hydrometrix HMX 2000) coupled with a thermistor temperature sensor diffused into the silicon die. The sensor

. The first set of powder samples (extracted gelatin, air-dried skin, and silica gel-dried skin) were equilibrated in desiccator maintained at 11.3% relative humidity environment by placing saturated lithium chloride solution (293 K). The equilibration

vessel, the glass tube was filled with 50 μL of water to obtain 100% relative humidity (RH) or a saturated salt solution to obtain humidities below 100% RH. When the substances were tested in the absence of moisture, the glass tube was empty. The

and ambient relative humidity during the day or year or season are also reflected in large variations in skin admittance, mainly because of changes in skin hydration [ 5 ]. In recent years, there is a growing interest in employing the

increases with increasing temperature. Relative humidity is the ratio in percentage between the absolute humidity and humidity at saturation: At saturation, p = P, and the relative humidity is 100%. For example, a pure cotton paper in a
