Last year was a very hard year with the COVID-19 epidemic, everyone saw the important role of the medical device industry. Meanwhile, the shortage of medical products caused by the epidemic has made medical industry a hot market worldwide. It is found that sensors and its relevant products received a lot of attention since they can enhance the functions of medical devices and ensure better treatment for patients. The application of sensors in the medical industry is very extensive and crucial. The use of sensors can greatly improve the safety, reliability and stability of medical equipment. Common fields that need sensors include respiratory equipment, anesthesia equipment, diagnostic and monitoring equipment, etc.
