The present invention relates to capacitive sensor packaging. An apparatus comprises a fingerprint sensor having a set of capacitive elements configured for capacitively coupling to a user fingerprint. The fingerprint sensor may be disposed under a control button or display element of an electronic device, for example one or more of a control button and a display component. A responsive element isresponsive to proximity of the user fingerprint, for example one or both of a first circuit responsive to motion of the control button, and a second circuit responsive to a coupling between the fingerprint and a surface of the display element. The fingerprint sensor is disposed closer to the fingerprint than the responsive element. The control button or display component may include an anisotropic dielectric material, for example sapphire. 本申请涉及电容传感器封装。种装置包括指纹传感器，该指纹传感器具有被配置成以电容方式耦合到用户指纹的组电容性元件。指纹传感器可以安置在电子设备的控制按钮或显示元件下面，例如，控制按钮和显示组件中的个或多个下面。响应性元件对用户指纹的接近敏感，例如，对控制按钮的运动敏感的第电路，以及对指纹和显示元件的表面之间的耦合敏感的第二电路中的个或两个。指纹传感器被安置在比
