Falls can lead to disability in the elderly and hip fractures are widely known as the last fall of life of the elderly. Falls have always been the first injury in the elderly. According to statistics, about 30% of people aged 65+ years fall each year. The potential risk of falls is no less than that of heart attack and stroke. The number of elderly people in China is growing, with 150 million people over the age of 65. About 40 million elderly people fall each year, and 40% to 70% of injuries caused by falls require medical treatment. Aging will lead to the aging of the body's functions, and the elderly are prone to fractures in the event of a fall. With osteoporosis, the bones of the elderly are relatively brittle, so they are easy to fall. It's estimated that 50% of these elderly people will have some degree of disability after surgery, and 20% of them will die from it. So the hip fracture is also called the final fall of life. As China's aging population continues to accelerate, more and more elderly people are living alone. If these elderly people are injured in a fall, it is likely to cause very serious consequences without on-time assistance. Is there a fall protection device to protect them from falling? S-airbag technology find a better solution to solve the fall problem. They develop a smart wearable anti-fall airbag vest, which is intelligent to detect the body movements of the wearer, and can autocratically deploy the airbag inside to reduce the force impact before they hitting the ground. It offers protection to the body with a soft-landing.
