Array film pressure sensor-based bad sitting posture and sedentariness identification system

The invention discloses a bad sitting posture and sedentariness recognition system based on an array type film pressure sensor, and relates to the technical field of sitting posture recognition, and the system comprises the array type film pressure sensor, a piezoelectric conversion acquisition module, a method for distinguishing a current user entity through low-power-consumption Bluetooth, and a sitting posture acquisition and processing flow. According to the bad sitting posture and sedentariness identification system based on the array type thin film pressure sensors, the flexible array type thin film pressure sensors are used and can be embedded into flexible supporting objects of a seat, experience is comfortable, and application is simple; a camera is not used, the privacy risk of a user can be avoided, the commercial feasibility is high, an acquisition module uses an in-phase proportion operational amplifier circuit to acquire pressure data, implementation is easy, energy consumption and cost caused b
