摘要： In one aspect, a method for registering a fingerprint profile on a mobile device includes detecting, at a fingerprint detection module having a rectangular shape, a contact from a finger associated with a swipe motion. The method includes responsive to the detected contact at the fingerprint detection module having a rectangular shape, capturing an image of the finger during the swipe motion. The method includes storing the image of the finger captured during the swipe motion as a registered fingerprint profile of an authorized user.

摘要： In one aspect, a fingerprint sensor device includes a substrate and a sensor chip disposed over the substrate. The sensor chip includes an array of sensor pixels configured to generate fingerprint data by sensing ridges and valleys of a surface of a finger contacting the fingerprint sensor device. Each sensor pixel includes a single sensor electrode an amplifier having an inverting terminal electrically connected to the sensor electrode and a non-inverting terminal electrically connected to a drive signal. The drive signal generates electric fields between the sensor electrode and at least one of the ridges and valleys of the surface of the finger contacting the fingerprint sensor device to generate a variable capacitor having a variable capacitance based at least partly on a distance between the sensor electrode and the at least one of the ridges and valleys of the finger.
