Embodiment Construction

[0037] like image 3 As shown, a flexible back posture correction device includes: a sitting posture state signal acquisition unit, a signal conversion unit, a data processing unit, a Bluetooth transmission module, a mobile phone APP, and a button battery;

[0038] The sitting posture state signal acquisition unit includes a flexible piezoresistive sensor, such as figure 1 As shown, the flexible piezoresistive sensor includes two membrane assemblies, the membrane assembly is composed of PDMS and the rGO layer coated on the front of PDMS, and the membrane assembly is prepared using 240 mesh sandpaper (GB / T9258-2000) as a template. The front has a ridge structure, and the heights of each ridge are different, but the overall height distribution is approximately normal; the two membrane modules face each other, some of the ridges are in contact, and some of the ridges are not in contact;

[0039] When there is a relative movement between the two membrane components, the peak ridg...

Abstract

The invention provides a flexible back posture correcting tool which comprises a sitting posture state signal collecting unit, a signal converting unit, a data processing unit, a Bluetooth sending module, a cell phone APP and a button cell. The sitting posture state signal collecting unit comprises a flexible pressure resistance sensor. The flexible pressure resistance sensor comprises two membrane assemblies. Each membrane assembly is composed of a PDMS and an rGO layer coated on the front face of the PDMS. The front face of each membrane assembly is of a peak ridge structure. The front facesof the two membrane assemblies are opposite, and the peak ridge structures of the two membrane assemblies make contact with each other. The flexible pressure resistance sensor fits and makes contactwith the back according to the muscle distribution, the peak ridge structures in the flexible pressure resistance sensor generate contact deformation according to muscle motions, a series of electricsignals are generated, and the sitting postures are monitored in real time. The sitting posture state can be most visually and accurately reflected, and the flexible back posture correcting tool is suitable for people of all ages.

Description

technical field [0001] The invention relates to sensor, signal processing technology, motion feedback technology, field of sports medicine, wireless sensor network, internet of things and other fields. In particular, it relates to a flexible and wearable motion regulation instrument based on a piezoresistive sensor with a peak-ridge structure and the motion regulation method belongs to the field of intelligent control. Background technique [0002] In recent years, as the symptoms of diseases caused by incorrect sitting postures during computer office work have increased day by day, people have paid more and more attention to maintaining correct sitting postures. Incorrect sitting posture is not only bad for mental outlook, but also easy to cause back pain, and even affect the spine and compress nerves. However, it is difficult to develop the habit of correct sitting posture relying on self-consciousness. It is often necessary to use some external traction posture correctio...
