MIT Youth List Review Gao Wei: Monitoring sweat sensor finalists in the "inventor" list
Previously, Dr. Gao Wei, a postdoctoral fellow at the University of California, Berkeley, had an idea: If there is a sensor that can detect the daily health of the human body, then people can keep abreast of their health problems. Gao Wei, who was in his early 30s, grew up in the rural area of ​​Xuzhou. He experienced a sudden death and was a cerebral thrombosis. He didn't know anyone at night and died a few months later. Now, he is witnessing the idea becoming a reality, and the fully flexible sweat sensor developed by him is available. This wearable sensor is shaped like a sweat-absorbent belt, and is equipped with a Bluetooth-equipped printed circuit board, 5 sensors with a diameter of 3 mm, a lithium battery that can support 10 hours of use, and body information by detecting sweat. And wirelessly transfer the data to the app on the phone. In August, the MIT Science and Technology Review's annual Young Heroes list was announced. Gao Wei was selected as one of the six Chinese on the list with this sweat sensor. Gao Wei Every year, 35 "World Outstanding Young Innovators" over the age of 35 are selected on the list. Gao Wei's postdoctoral tutor Ali Javey was one of the finalists seven years ago. This year, Ali Javey nominated Gao Wei to the MIT Technology Review. Gao Wei said that many of his idols in academia and science and technology have been on the list, and now he has added this award to his resume. After completing his studies at Huazhong University of Science and Technology and Tsinghua University, Gao Wei went to the University of California, San Diego to study for a Ph.D., and in 2014, he began his postdoctoral research at Berkeley, California. From this time, he began to use sweat sensors as research directions. Wearable sweat sensor Wearable sensors are becoming a trend, and Gao Wei also believes that it will play a pivotal role in personalized medical care in the future. However, unlike the sensors on the market that detect physical activity and life characteristics such as heart rate and body temperature, Gao Wei introduced to the author that the biggest highlight of this sweat sensor is to detect health from the molecular level, that is, to use human body fluids. The content of chemical components reflects the characteristics of life. a few microliters of sweat, non-invasive detection of disease It is very common to use body fluids to detect physical conditions. Most hospital tests rely on various body fluids. But Gao Wei's idea is daily, no need to go to the hospital for testing, which means that non-invasive testing is preferred. In this way, blood with body information is excluded, and obtaining blood means that there is a wound, which is not practical for daily real-time detection. In addition, what other body fluids, carrying a lot of life information, and easy to obtain? Gao Wei saw the possibility of sweat. The chemical composition of sweat is diverse and easy to obtain. In the initial version of the sweat sensor, Gao Wei set five detection dimensions: glucose, lactic acid, sodium ion, potassium ion and body surface temperature, and also continuously added heavy metal, chloride ion and other detection objects. These specific test subjects can peek into the secrets of the body. Gao Wei said that it is already medically convinced that sodium ions in the blood can detect the dehydration of the body, and chloride ions can be used to diagnose cystic fibrosis. Glucose in the human body is associated with glucose in the blood and can be used to detect diabetes. But Gao Wei admits that sweat is not a body fluid that has been studied on a large scale. There are still many unknown things. Although the trend is optimistic, it takes more time. On the one hand, the connection between sweat and blood in various components needs to be confirmed by a large number of clinical trials. On the other hand, sweat may be a rich mineral of life information, and more detection dimensions have yet to be developed.
