Out of plane displacement is a major source of error in quantitative blood flow and elasticity imaging. The use of a 1.5 matrix array is investigated forming a 3/spl times/3 matrix of partially overlapping beams allowing us to estimate the 3D displac

A new type of fingerprint sensor is presented. The sensor maps the acoustic impedance of the fingerprint pattern by estimating the electrical impedance of its sensor elements. The sensor substrate, made of 1-3 piezo-ceramic, which is fabricated inexp

A new type of fingerprint sensor is presented. Based on 1-3 piezo composites the sensor provides resolution up to 50 um. Using FE modeling the study presents the numerical validation of the basic principle, an optimized pillar aspect ratio, spatial r

Recent progress reported from different groups have shown that 3-D ultrasonic imaging is possible using electronic beam steering with 2-D matrix arrays having rare and random array patterns. In simulation studies Turnbull et al (1990) have shown that
