随着科学技术的不断发展，用户对电子设备(如手机，平板)的功能要求越来越高，而压力感应功能成为电子设备进一步提高用户体检的重要功能。电子设备利用压力检测装置实现压力检测后，可以利用压力维度的信息进行电子设备相关应用功能的开发。
压力检测装置一般包括通过支撑件分隔开的两个相对的感应电极，其中一个感应电极位于柔性电路板上，然后柔性电路板通过粘结的方式贴合在金属框上。当有压力施加在该压力检测装置中的、与柔性电路板上的感应电极相对的感应电极时，在支撑件的支撑下，该相对的感应电极会产生结构变形，从而使得这两个感应电极间的感应电容发生变化。根据这两个感应电极间的感应电容的变化可以确定两个感应电极间的距离的变化量，然后根据这个变化量可以确定施加在该压力检测装置上的压力。
其中，由于金属框表面及支撑感应电极的柔性电路板(Flexible Printed Circuit，FPC)的平整度较低，会使得确定的两个感应电极间的距离的变化量的灵敏度较低，从而影响压力感应的性能，最终影响用户的体验。
