1. A posture measuring device, comprising:
two fiber optic;
a signal processing unit electrically connected to the two fiber optic sensors respectively;
a power supply unit electrically connected to the signal processing unit;
a prompting unit and/or a wireless communications unit electrically connected to the signal processing unit; and
a grid stress element;
wherein the two fiber optic sensors are arranged side by side or parallel arranged in front and rear; the fiber optic sensors detect changes in optical signals generated from changes in applied pressures on the sensors, the signal processing unit analyzes a posture of a user on the basis of changes in optical signals generated from changes detected by the fiber optic sensors in applied pressures on the sensors; when the two fiber optic sensors are arranged side by side, the grid stress element is placed on a rear side or a front side of an upper surface connected by the two fiber optic sensors side by side; when the two fiber optic sensors are parallel arranged in front and rear, the grid stress element is placed on a left side or a right side of the upper surface connected by the two fiber optic sensors in front and rear.
