“…According to this array concept and the small size of each cell, the design issues encounter different challenges compared to other typical MEMS capacitive sensors and actuators which assist from only one capacitive element (such as the works of Nabipoor andMajlis 2004 andGanji andMajlis 2006). Each sensor cell acts as a pixel to record the pressure amount induced by the ridges on the fingertip to make a grayscale image of the fingerprint (Fig.…”

Sensitivity improvement is a challenging issue in miniature pressure sensors. To improve sensitivity and linearity of the device, a wide micro beam structure has been proposed to gauge capacitance changes caused by the applied pressure in a capacitive MEMS fingerprint sensor. Bending behavior of the device and the effect of the protrusion geometry on partial loading of the micro beam has been analytically investigated. Based on the idea of efficient loading of the wide micro beam, an improved design for the capacitive fingerprint sensor is developed to increase sensitivity. It is shown with FEM simulations that the micro wide beam design is superior to the common membrane based MEMS fingerprint sensors in terms of sensitivity and linearity.
