Problems solved by technology

The sensor module of the existing back cushions with the function of sitting position monitoring usually requires a power supply for power supply, which increases the size of the back cushion, complicates the structure, and is not conducive to safety and environmental protection. At the same time, the operation of charging or replacing the power supply also causes the use process to cumbersome

Abstract

The invention discloses a self-powered human body sitting posture monitoring back cushion. The back cushion comprises a main body part and a sensing part, the main body part comprises a back cushion base, a stepped groove, a power module, a signal processing module and a communication module, the sensing part comprises a supporting base, a flexible electrode layer, a lower friction layer, a paper folding structure layer, an upper friction layer and an electric lead, the lower friction layer is composed of a lower friction layer base and frustum-shaped protrusions, and an integrated forming process is adopted. According to the self-powered human body sitting posture monitoring back cushion based on the friction nanometer generator principle, electric signals are generated through contact and extrusion between the upper friction layer and the lower friction layer, an external power source does not need to supply power to the sensing module, and the back cushion has the advantages of being simple in structure, safe to use and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of friction nano power generation, in particular to a self-powered human body sitting posture monitoring back cushion. Background technique [0002] With the transformation of the way of life and work, people will keep sitting for a long time every day, and the problem of sedentary is becoming more and more prominent. As the time of sitting increases, people tend to choose more "comfortable" bad sitting postures, such as leaning forward, half lying down, crossing legs, etc. These bad sitting postures will reduce the force of muscles and ligaments, and make bones and joints Under greater force, the joints and bones are under high pressure for a long time, which will lead to serious harms such as cervical spondylosis, lumbar disc herniation, body deformation, vision loss, overweight and obesity. Therefore, it is necessary to detect the sitting posture of the human body, and provide feedback and reminders for ...
