According to foreign media reports, although you must have heard of health monitoring implanted sensors, most of these devices must be removed surgically once they are no longer needed. The device, invented by a team at Penn State University’s Institute of computing and data science, is thin and flexible enough to detect different forms of nitric oxide (no) and nitrogen dioxide (NO2) in the body. < / P > < p > we know that nitric oxide is naturally produced by the human body and promotes blood flow by relaxing and dilating blood vessels. However, nitrogen dioxide may exist in the environment. If inhaled, it may lead to chronic obstructive pulmonary disease and other diseases. < / P > < p > in general, patients recovering from medical procedures will use external devices to monitor the gas. However, according to Professor Huanyu Cheng, the lead scientist of the study, the device is not only bulky but may not be as accurate as the implantable sensor. However, the biodegradable silicon based materials, the biodegradable silicon-based devices, and other flexible components made by the team. It is possible to determine the concentrations of no and NO2 in the surrounding environment based on the readable changes in the electrical characteristics of the sensor. < / P > < p > to date, tests in humid environments and aqueous solutions have shown that the sensor can operate in adverse physical conditions throughout the patient’s recovery period prior to dissolution. After 12 years, “world class Super project” Shantou Bay Tunnel ushers in a historic breakthrough today
