The monitoring module is used for monitoring the posture change of human vertebra, the processing module is used for receiving and processing the monitoring data from the monitoring module and sending a control instruction to the reminding module, the reminding module is used for sending a reminding signal to a user, and the power module is used for providing power for the monitoring module, the processing module and the reminding module.

As shown in fig. 1-4, in the matrix human spinal posture monitoring system of the present invention, the strain gauges of the transverse strain sensor 4 and the longitudinal strain sensor 5 include a rectangular substrate 7, a hairy carbon nanowall 8 disposed on the upper surface of the substrate 7, a plurality of carbon nanotubes 9 disposed on the carbon nanowall 8, and electrodes 10 connected to two ends of the carbon nanowall 8, wherein the substrate 7 is a flexible insulator, the upper surface of the substrate 7 and the carbon nanowall 8 are in a harmonic shape, the carbon nanotubes 9 are vertically disposed on the carbon nanowall 8, the length of the carbon nanotubes 9 is about 1-10 μm, the distribution density of the carbon nanotubes 9 is 1000-5000-, the carbon nanowall 8 is manufactured by a chemical vapor deposition method, the thickness of the carbon nanowall 8 is 0.5-2 μm, the plurality of carbon nanotubes 9 are manufactured by the chemical vapor deposition method, the number of the six-axis sensors 6 is 2-5, the number of the six-axis sensors is 3, the processing module is provided with a wireless communication unit, and the reminding module comprises a vibration reminding device and a voice reminding device.

When the foil gage receives the exogenic action, produces upwards or when downward deformation, certain change can take place for the resistance value, specifically is: when the strain gauge deforms upwards, the carbon nanotubes 9 at the wave trough of the carbon nanotube wall 8 are in mutual 'dense contact', more connecting channels are generated compared with the normal state, the effective conducting length of the connecting channels begins to be reduced, and the resistance value Rx at the moment is reduced according to the resistance law; on the contrary, when the strain gauge is deformed upward, the contact portion between the carbon nanotubes 9 starts to decrease at the valley of the carbon nanotube wall 8 and becomes more sparse than the normal state, so the effective conductive length starts to increase, which can be obtained according to the law of resistance, and the resistance value Rx becomes larger.
