A system (28) for addressing an array (50) of resistive sensors is provided, where each sensor (56) has a variable resistance that assumes a predetermined value in accordance with a characteristic of an object being measured by the sensor, and the sensors are arranged in an array having rows (52) and columns (54). The system addresses a predetermined sensor in the array by applying a first predetermined voltage to select a particular row of sensors having the predetermined sensor and by applying a second predetermined voltage to select a particular column of sensors having the predetermined sensor. The system also limits the current (64) through sensors in the array that are not the predetermined sensor. A method of addressing a sensor within an array of sensors is also provided. |
