Sensors also play a very important role in the medical field. Medical sensors integrate a variety of advanced technologies such as nanotechnology, biotechnology, power supply technology and new communication technology, and have obvious advantages such as high sensitivity, miniaturization, convenience, low cost and interconnectivity. There are many types of sensors for medical applications, which can play different roles in the medical field. Generally speaking, medical sensors have multiple purposes such as detecting biological information, clinical monitoring, and controlling the physiological processes of the human body.
According to the working principle, medical sensors can be divided into chemical sensors, biological sensors and physical sensors. Temperature sensors belong to the category of physical sensors. This year, temperature sensors have played an important role in medical equipment in the fight against the coronavirus. For example, medical temperature sensors required in the ventilator. Due to the virus infection, breathing difficulties is a typical symptom of critically ill patients, and the ventilator can keep the alveoli at a certain pressure at the end of expiration, increase the functional residual volume, prevent alveolar collapse, thereby changing the ventilation and the ventilation function realizes the purpose of assisting breathing therapy for patients. Multiple sensors are designed and installed in the ventilator to control airflow, pressure and humidity in real time, continuously and accurately, and maintain the patient's continuous breathing function. Therefore, breathing equipment will use gas mass flow, pressure, humidity, temperature, and magnetic sensors to monitor and control airflow, pressure, temperature and humidity and other indicators, while supporting and ensuring stable motor control system operation.
With the improvement of people's living standards, people will pay more and more attention to their own health problems. At present, more and more smart electronic devices are linked to health detection, and the realization of health monitoring or other functions is inseparable from the cooperation of sensors. In other words, temperature transducer is not limited to the diagnosis and treatment of the coronavirus epidemic or medical disease. It can realize the detection of daily health status and protect people's lives and health.
