Smart insole predicts disease

Recently, a wearable smart insole was launched at Nanjing Chuangsen Medical Technology Co., Ltd. in Zijin (Jiangning) Science and Innovation Zone. Chuang Technology CEO Li Qin introduced that the core of this technology is a kind of special fabric with sensing function. It can measure pressure distribution and other indicators according to people's walking and is applicable to medical, sports, military and other fields.

Diabetic foot refers to a lesion caused by destruction of the foot or lower extremity of diabetic patients due to factors such as diabetic vasculopathy and (or) neuropathy and infection. According to statistics, 15% of the world's diabetic patients develop foot ulcers at least once in their lifetime. In the United Kingdom, 10.2% of diabetic patients have had foot ulcers, and China is also more than 10%. The most severe patients are even amputated.

Li Qin said that their R&D team is a group of undergraduate students enrolled at Zhejiang University, with doctoral and master's degrees in the United States, the Netherlands and other prestigious universities completed the "returnees", team members in foreign countries to focus on research and development in this area, the current project is Included in Nanjing 321 talent projects.

Why smart insoles can predict disease? The reason is that the fabric for making insoles is magical. This fabric is made of polymer nano-cloth as a medium and has a sensing function. Every step, the stress point and pressure of the foot will be uploaded in real time. To the cloud. “The future is the era of big data viewing. It seems that unrelated masses of information are transmitted to the cloud for analysis. This is a valuable first-hand information. For example, to determine the probability of diabetic foot, if a certain part of the foot is continuously under pressure, Long, it will cause blood vessels to fail, the probability of ulceration will be higher. We will remind patients, in addition, based on these data, we can also tailor the physical therapy insoles for patients to ease the pressure on the affected area.” Li Qin introduced .

Smart insole is not only a medical aid, but it can also be used in sports, such as stress from the foot, to determine whether the athlete's posture is in the best condition and whether there is room for improvement. In the military field, the rear command can not only locate the geographical position of the soldier, but also judge the topography and landform based on the forces of climbing and downhill.

According to reports, Chuangsen Technology has already obtained angel funds and is in the process of industrialization. In order to maintain its innovation drive, the company has established a close cooperation relationship with the Department of Information and Electrical Engineering of Zhejiang University and the embedded laboratory of the State University of New York at Buffalo. “At present, smart insoles have potential overseas orders and are considered by US medical institutions. It is expected that trial sales will begin next year. In the future, we plan to develop extended products such as sensing sheets,” said Li Qin.
