摘　　要：柔性器件的机械柔韧性、可拉伸性、形状适应性及制造的可扩展性较强.然而,柔性器件所需的材料制作门槛较高且成本昂贵.以纸张为基板,利用石墨的压敏特性,采用简单工艺制作了纸基重力测量器.石墨电阻的阻值变化与重物的质量成正比,因而可以通过测量电阻的变化值反映重力的大小.该测量器的制作简便,成本低廉,复现率较高,且能够满足物理实验教学需求.Flexible sensors are stronger on mechanical flexibility,stretchability,shape adaptability,and manufacturing scalability.However,the fabrication for materials required for flexible sensors is high-qualified and costly.This paper employed paper as the substrate and utilized the pressure-sensitive properties of graphite to fabricate a novel paper-based gravity sensor through a simple fabrication process.Research findings indicated that the resistance change was directly proportional to the mass,thus the gravity’s magnitude could be reflected by measuring the resistance change.This type of flexible sensor has the advantages of simple fabrication process,low cost and high reproducibilit.It could meet the requirements of physics experimental teaching.
