SHORT-DISTANCE MAGNETORESISTANCE IMAGING SENSOR ARRAY

摘要

A low profile magnetoresistive imaging sensor array (71) based on the principle of magnetic induction, which reduces a distance (98) between a medium imaging sensor array (71) and a medium (10) by optimizing the arrangement of an application integrated circuit and a sensing element array and using an electric connection technology which can reduce the distance (98) between the medium imaging sensor array (71) and the medium (10), thereby increasing the resolution of the existing medium imaging sensor. The low profile magnetoresistive imaging sensor array (71) comprises a sensing element array and an application integrated circuit, and also comprises a circuit which provides a power for the sensing element array, a magnetoresistive sensing element array selection circuit, a signal amplification circuit, a digitizer, a memory circuit, and a microprocessor. Additionally, the sensing element array comprises at least one magnetoresistive sensing element.
