Research status and development trend of smart sitting posture correction garment
Significance An analysis based on more than 30 years of data suggests that the number of cases of low back pain is increasing worldwide,and there will be more than 800 million people with low back pain worldwide by 2050.The reason for this phenomenon is that the development of modern education and technology has led to a dramatic change in the way people live and work,and sitting has become the most common posture used today.The sedentary process is accompanied by a variety of poor sitting posture,which causes unnatural bending of the spine and uneven distribution of forces on the spine and back,thus leading to spinal disorders,such as lumbar muscle strain,lumbar disc protrusion,and scoliosis.According to medical research,correcting sitting posture is an effective way to prevent and reduce back pain.Therefore,the development of wearable products for posture correction is necessary.Progress The orthopedic wearable products currently available are categorized according to the way they are worn,and can be divided into head-mounted,miniature wearable and clothing wearable.From the comparison of two garment wearable products,including sitting posture correction belts and sitting posture corrective garment,it was found that the physical stretching of the orthopedic straps will have a strong sense of constraint on the body,and at the same time,the sitting posture correction belts mainly relies on inertial sensors,and the monitoring area is relatively limited.The development of smart textiles for creating smart sitting posture correction garment makes up for the shortcomings of sitting posture correction belts,which combines comfort and functionality and has greater prospects for development.This is followed by a specific analysis of the three key technologies of the sitting posture correction garment system,i.e.,wearable sensing technology,system identification technology,and recognition feedback alerting technique.The monitoring methods of two major wearable sensing systems,microelectromechanical systems and smart textile systems,are described and compared.Based on the types of signal recognized by the wearable sensor,the principle of discriminating bad sitting postures is explained.The feedback methods in the smart sitting posture correction garment are introduced from three senses i.e.,visual,auditory and tactile,and the results show that the multi-sensory recognition feedback mode is more effective.Conclusion and Prospect Smart sitting posture correction garment has great advantages and practical value.It can expand the monitoring area,detailing and focusing on the areas of poor sitting posture,the development of electronic textiles makes smart sitting posture correction garment more comfortable,and it can have the dual function of passive and active posture correction,which can help to improve the poor sitting posture of human body more effectively.In the future,smart sitting posture correction garment should also be developed towards the following directions.① Use of flexibility of electronic equipment.In the future,sensing elements and vibration feedback elements both can try to replace with intelligent textiles,so as to better integrate in the clothing.(2)Enhanced accuracy of the system identification.Since the electrical signal collected by the textile sensor is affected by the sensor material,monitoring position and other factors,it is also necessary to standardize a criterion to obtain an accurate threshold classification for poor sitting posture.③ Focusing of feedback mode.Multi-sensory feedback mode is the focus of future research,the future should be for different groups of people to take different feedback mode,and set up feedback mechanisms that can be adapted to different occasions.④ Enhancement of human-computer interaction.The current clothing only plays the role of monitoring and feedback,but does not realize the real interaction.The future also needs to enhance human-computer interaction,guide the user to exercise.⑤ The safety of the system clothing.Clothing not only needs to be considered for the safety of the use of electronic components,but also needs to protect the privacy and security of users.It is believed that smart sitting posture correction garment will have a good development prospect in the field of healthcare and health monitoring.
