In this paper a new design of MEMS capacitive fingerprint sensors is presented. The capacitive sensor is made of two parallel plates with air gap. In these sensors, the capacitance changes is very important factor. It is caused by deformation of the upper electrode of sensor. In this study with making slots in upper electrode, using T-shaped protrusion on diaphragm in order to concentrate the f...

Interface Electronics for Ultrasonic Transducers by Hao-Yen Tang Doctor of Philosophy in Engineering Electrical Engineering and Computer Sciences University of California, Berkeley Professor Bernhard E. Boser, Chair Ultrasound has long been used for medical imaging. Recent advances of miniaturized MEMS ultrasonic transducers new applications such as gesture recognition, personal fitness devices...

We present in this paper a novel tactile fingerprint sensor composed by a single row of microbeams realized by the way of front side bulk micromachining from a standard CMOS circuit. When the user passes his finger on the sensor, the ridges and the valleys that compose the fingerprint induce deflections in the different microbeams. Using a piezoresistive gauge placed at their base, the deflecti...

Manual fingerprint classification algorithms are very time consuming, and usually not accurate. Fast and accurate fingerprint classification is essential to each AFIS (Automatic Fingerprint Identification System). This paper investigates a fingerprint classification algorithm that reduces the complexity and costs associated with the fingerprint identification procedure. A new structural algorit...

coronary artery disease (cad) is the most important cause of mortality and morbidity in the world. the knowledge of major risk factos can be useful in prevention of cad. there is no known major risk factof in many patients with myocardial infarction (mi). the dermatoglyphic pattern in patients with myocardial infarction is an interesting matter and little information is available about this rel...

autism is a neurodevelopmental disorder originating from early childhood; nevertheless, its diagnosis is in older ages. in addition to heredity, environmental factors are also of great significance in the etiology of the disease. dermatoglyphic patterns, albeit varied, remain stable for a lifetime and yield a large number of patterns upon examination. studies have shown a significant associatio...
