Abstract
In the field of micro-electromechanical systems (MEMS) for autofocus camera systems, a MEMS device comprises a fixed part, a movable platform with an image sensor, and temperature sensors on both the platform and fixed part. A processor calculates the temperature difference to determine the platform's displacement. This method eliminates the need for additional capacitive or piezoelectric components, reducing complexity and cost. The described technology is particularly useful in consumer electronics, such as smartphone and automotive cameras, where precise focus control may be vital.
