    • Disclosed is a device for varying capacitance which pertains to the field of application of electronic devices and components. The technical essentials of the present invention lie in that: two dielectrics are disposed in parallel with an isolation layer interposed therebetween; the two dielectrics each are connected to an electrode at the same one end face thereof; the other end face of each of the two dielectrics is provided with an elastic conductive pad; a gasket is provided between the two dielectrics and the elastic conductive pads. The relative position and compressed area between the elastic conductive pads and the dielectrics vary according to the magnitude of the external force so that the capacitance between the electrodes of the dielectrics is varied accordingly within a certain range. Therefore, once the value and the variation of the capacitance between the electrodes are measured, the magnitude and the status of the external force which brings about the variation of the capacitance can be obtained. The device of the present invention has a simple structure and high sensitivity. Also, it has a definite zero initial value and a maximum value of the capacitance, and therefore is easy for handing and measurement.
    • 公开了一种用于改变电容的装置,其涉及电子装置和部件的应用领域。 本发明的技术要点在于:两个电介质与插入其间的隔离层平行设置; 两个电介质各自在同一个端面连接到电极; 两个电介质的每一个的另一个端面设置有弹性导电垫; 在两个电介质和弹性导电垫之间提供垫圈。 弹性导电垫和电介质之间的相对位置和压缩面积根据外力的大小而变化,使得电介质的电极之间的电容相应地在一定范围内变化。 因此,一旦测量了电极之间的电容的值和变化,就可以获得导致电容变化的外力的大小和状态。 本发明的装置结构简单,灵敏度高。 此外,它具有确定的零初始值和电容的最大值,因此易于处理和测量。
