"Our technology is the only one in China and the only one in the world." There are many stories of challenging technical barriers in Weici Technology. Recently, Weici Technology announced the completion of Series A financing of over 100 million yuan. So far, in two years since its establishment, it has completed four rounds of financing of hundreds of millions of yuan.
is the powerful tool behind the rapid growth of Weici Technology. As a domestic leader in commercial quantum magnetic field sensing technology, it has used the core technology of atomic magnetometers as its platform since its establishment. It has not only broken the US monopoly on commercial technology in this field for many years, but also achieved complete independent control of the underlying technology and core devices. Aiming at the precise diagnosis of major heart and brain diseases and commercial application in the field of brain science , it took the lead in successfully developing high-end medical imaging equipment such as magnetocardiograph and magnetoencephalograph with completely independent intellectual property rights, making my country the first country after the United States. Two countries with the entire industrial chain of quantum biomagnetic field imaging. Cai Bin, the founder and chairman of
Weici Technology, told the Beijing News Shell Finance reporter that Weici Technology hopes that ordinary patients can realize the magnetocardiogram test that has been difficult to popularize because it is too expensive for the benefit of ordinary patients. patients with cardiovascular disease.

Non-invasive magnetocardiogram examination, a powerful tool for early diagnosis of cardiovascular diseases
Weimagnetic Technology’s core technology atomic magnetometer has broken through the "stuck neck" problem that has plagued our country for many years.
If the accuracy of measuring the magnetic field can be "fine" to one billionth of the earth's magnetic field , you can "see" the magnetic field generated by your own heart and brain. Applying this technology to medical treatment can achieve non-invasive detection of cardiovascular diseases, brain diseases, etc. Ordinary people can diagnose related diseases without taking imaging or CT.
To achieve this process requires ultra-highly sensitive magnetic field detection capabilities, the research, development and commercialization of this technology have been monopolized by foreign companies. However, Weici Technology's commercial products have tied with the only American competitor in core technical indicators, and have surpassed them in terms of multi-channel collaborative work, system integration, reliability, and user-friendliness.
"When we were catching up with foreign technical indicators, we found that the difficulty of breaking through the technology itself was only 40%, and 60% of the difficulty was how to put this technology into mass production. During this period, the team weathered the difficulties caused by the epidemic outbreak. Difficulties include delays in progress, being stuck by American suppliers, cultivating domestic suppliers and self-developed equipment," Cai Bin said in an interview with the Beijing News Shell Finance reporter. The quantum magnetic field measurement technology currently mastered by
Weimag Technology can detect magnetic fields of the order of 10 minus 15 Tesla, which is equivalent to one billionth of the earth's magnetic field. At this sensitivity, humans will be able to measure The extremely weak heart magnetic field, brain magnetic field, images, and the resulting magnetocardiogram and magnetoencephalography technology make it possible to detect non-invasive cardiovascular diseases and brain diseases.
This technical route is currently the most sensitive technical means for human magnetic field measurement, which brings broad application prospects. Based on core technology, Weici Technology was the first in China to develop an atomic magnetometer magnetocardiograph for accurate diagnosis of cardiovascular diseases, and obtained the first medical device registration certificate for such a product in China. In external descriptions, magnetocardiography has also become a powerful tool for detecting early cardiovascular diseases.
"China Cardiovascular Health and Disease Report 2020" shows that the number of people suffering from cardiovascular diseases in my country is about 330 million. The use of magnetocardiography technology can not only determine whether there is disease, but also relatively accurately determine the location of the lesion, which can provide a more accurate diagnosis of cardiovascular disease. Compared with detection methods such as CT, magnetic resonance imaging, and coronary angiography, magnetocardiography technology has no radiation, does not cause damage to the human body, and can achieve non-invasive and fast detection. "Using a magnetocardiograph, combined with an AI algorithm, we can extract the heart magnetic field signal of the person being tested, and even the heart magnetic field signal of the fetus in pregnant women, thereby achieving non-invasive detection." Cai Bin said.
"Only spending a few hundred yuan" allows ordinary people to do "expensive examinations"
Shell Finance reporters visited Weici Technology Company and saw that the magnetocardiograph developed by the company is similar in size to the small space capsules used for people to rest in shopping malls. It can be used by an adult to lie on it, and the testing process only takes 90 seconds. The magnetocardiogram pattern of the person being tested will be displayed on the screen of the instrument.
Shell Finance reporter learned that Weimag Technology’s current main technical route is the “atomic magnetometer technology” in magnetic field measurement, and it has also gone through a difficult entrepreneurial journey to break the “stuck neck” problem. The commercialization scenario of
magnetocardiogram has been implemented at home and abroad for decades, but the "superconducting quantum interference magnetometer" technical route is used for magnetic field measurement.
Cai Bin said that instruments that use superconducting technology to measure cardiac and brain magnetic fields require strict conditions. In addition to the need for a low-temperature environment for the equipment itself, additional shielding rooms need to be built, with a total weight of about tens of tons and a long construction period. Up to 4 to 6 months. In terms of underlying technical barriers, Weici Technology focuses on commercializing and miniaturizing products, shrinking products that are huge, expensive and weighing one ton into the size of a tablet, and reducing the selling price to only tens of thousands of dollars. In the past few years, there was only one American company in the world with products of the same level. It had formed extremely high technical barriers in terms of measurement principles, underlying algorithms, device preparation, material ratios, mass production processes, etc. For this reason, Weimag Technology The technological breakthroughs achieved are particularly valuable.
Cai Bin told Shell Finance reporters that the current price of foreign magnetocardiography equipment purchased in China is about 1,000 yuan per use, and the price of magnetic brain testing is several thousand yuan. Weici Technology is committed to making cardio-magnetic and brain magneto-magnetic equipment get rid of bulky size, harsh installation conditions and high maintenance costs. At the same time, the cost of equipment is lower, so that ordinary people can also perform cardio-magnetic and brain magneto-diagnosis. degree, "Our goal is to allow ordinary patients to spend a few hundred yuan to achieve magnetic heart testing and brain magnetic testing."
Gathering elites to enter the medical field and building higher technical barriers
Although it has only been established for two years, Weici Technology has Already have a halo. Its strong R&D team, with core members composed of executives from Fortune 500 companies, national high-end talents from Tsinghua University, Nanjing University, high-level innovative talents, postdoctoral fellows and doctors, has expertise in measurement, quantum. It has more than 20 years of technology accumulation in physics , medical imaging, etc.
Cai Bin graduated from Beijing University of Aeronautics and Astronautics. After studying in the UK, he studied all the way to a postdoctoral degree. When he was a student, he was engaged in aerospace precision measurement. Since then, he has been engaged in measurement technology work in the British National Advanced Manufacturing Technology Center, the British Jaguar Land Rover and other institutions. In more than ten years of foreign work experience, Cai Bin has practiced most how to combine a bottom-level technology to quickly realize product transformation. In his view, this experience is very important for the rapid development of Weici Technology.
In 2018, Cai Bin received an invitation from a domestic precision measurement project and returned to China to overcome technical difficulties. In order to meet the country's technical requirements, he assembled a number of top domestic talents in this field and established a research and development team covering quantum physics, optical engineering, precision measurement, integrated circuits and other fields. After completing the project requirements, Cai Bin realized that precision measurement technology could also play a huge role in the field of people's livelihood, so he established Weimag Technology in 2020 and led the team to prepare for commercialization in the medical field.
“When our company was just established, we encountered the outbreak of the new coronavirus pneumonia, and many processes were forced to be delayed.” Cai Bin told Shell Finance reporters, “Due to the cutting-edge nature of the non-magnetic technology field, many equipment and supply chains are firmly controlled by the United States. This forces us to cultivate domestic suppliers and conduct research and development of production equipment ourselves. In fact, this test for our technical team is not only in quantum physics and optics, but also in all cross-cutting fields. For example, we are in In terms of materials science, we have made breakthroughs in the purification and doping of alkali metal , and we have also conducted self-research on the packaging of optoelectronic chips and laser and other production line equipment. In the process, we have created higher technical barriers. "
In the future, Cai Bin believes that the goal of Weimag Technology will not only be in the medical field, but also the application scenarios of magnetic field measurement technology itself will be more diverse, such as using drones to carry our magnetic field detection equipment for mineral exploration, non-destructive testing, geological disaster early warning, Security testing, etc.
