36 KR recently learned that moment Qiao Industrial has completed nearly 10 million yuan seed round financing, the investor is Guoxin Xihai Fund, Inspur Capital as a long-term exclusive financial adviser, this round of financing is mainly used for digital factory construction and production line laying.

Established in November 2023, the company focuses on the research and development of flexible fiber sensor technology. By combining a number of innovative technologies such as fiber pressure sensor, fiber electrode and tension sensing fiber with related algorithms, the perception, transmission, calculation and control of ECG, pressure and tension signals are completed.

0190-01401 In terms of technical principles, traditionally, flexible sensors are mostly thin film pressure sensors, through resistance, capacitance, piezoelectric and other induction mechanisms, through the sandwich structure of the sensing material coating on the flexible substrate to achieve sensing characteristics. However, due to the limitations of substrate materials and processes, such sensors have obvious limitations in foldability, elasticity and permeability. In the long-term use of large-area scenes, it is also faced with the problem that it is easy to fall off and the change of the thickness of the sensing layer needs to be calibrated regularly.

Zhang Jingqi, CEO of Moment Qiao Industry, introduced to 36kR that compared with similar technologies, the essential difference of flexible fiber sensor technology is that the electrode coating, piezoresistive coating, and coating substrate all achieve fibrosis. The form of the fabric makes its flexibility, foldability, breathability, comfort and durability are improved, the minimum folding radius is less than 0.2 mm, and the application scenarios are also expanded and enriched.

In terms of conventional sensing performance, the flexible sensor has passed several durability tests such as Z-folding, kneading, and high-strength impact of 3 mpa, and its reliability is guaranteed, and there is a great breakthrough in the sensor range.

“The upper limit of the range of piezoresistive and capacitive pressure sensors on the market is basically about three or four hundred kpa, but the range of the fabric sensor can reach about 10 times this value,” Zhang Jingqi explained, the principle is mainly in the fiber configuration of the sensor, “the multi-layer structure inside the fiber produces more conductive channels when under pressure. The electrode fiber and piezoresistive fiber structures create more occlusion, and as a result, the resistance between the electrode fibers is reduced and the sensing range increases.”

0190-01401 In addition to technology research and development, it is more important to land flexible sensors to industrial standards and achieve mass production. In this regard, relying on China’s local textile factories, after thousands of proofing experiments, Qiaoqiao Industry has optimized the spinning nozzle, equipment link and temperature and humidity control of textile machines, and achieved the improvement of production efficiency and consistency, and the production yield has reached 95%.

According to the core application scenario, at present, the company has laid out three product lines: the care series aimed at old-age medical care, the industrial vehicle series applied to automobile enterprises, and the precision series focusing on robot skin and scientific research.

Old-age medical bedsore pad is the first product of “Care series” to achieve scale production and delivery. By obtaining the real-time pressure distribution map of the whole person in bed, recording the duration of pressure in different parts of the human body, and linking it with the nursing AI nursing assistant developed by Qiaoqiao, the product can not only monitor and warn the risk of bedsore in real time, but also warn the risk of stroke according to the data such as breathing and shaking, and integrate relevant information into the background management system. Family members, nurses, nurses, deans and other relevant personnel can understand the status of the elderly through different ports of the APP and implement care.
