Sitting posture measuring device, intelligent cushion and intelligent seat

An intelligent cushion, compressing:

• a cushion body;
• and
• a posture measuring device disposed in the cushion body;
• the posture measuring device comprising:
• two fiber optic sensors;
• 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.

An intelligent seat, comprising:

• a seat body;
• and
• a posture measuring device disposed in the seat body;
• the posture measuring device comprising:
• two fiber optic sensors;
• 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;
