摘要

木材是一种广泛使用的材料。木材含水率的评估至关重要，因为含水率值的变化会导致材料的收缩或膨胀，从而导致腐烂或真菌生长。提出了一种低成本的平面电容式传感器，可以快速、无创地测量木材湿度。该传感器被图案化为FR4衬底上的螺旋电极。测定了5种木材样品在0 ~ 82%范围内的含水率。因此，本研究探讨了利用平面电容结构测定木材含水率的可行性。

Wood Moisture Content Measurement using planar Capacitive Sensors

Wood is an extensively used material. Assessment of wood moisture content is crucially essential as variations in moisture content values causes shrinkage or swelling of the material leading to decay or fungi growth. A low-cost planar capacitive transducer is proposed that provides quick and noninvasive measurement of wood moisture. The sensor is patterned as a spiral electrode over FR4 substrate. The content of moisture in 5 species of wood specimens in the range of 0– 82% has been examined. Thus, the research investigates the feasibility of wood moisture content determination using planar capacitive structures.
