Sensor is the core component of information technology and the only functional device for data acquisition. The data it collects can ensure the smooth operation of the entire sensing, transmission and processing information system. With the rapid development of emerging technologies such as artificial intelligence and the Internet of Things, the sensor market, including NTC temperature sensors, is expanding. Relevant data show that the market size of my country's sensors has exceeded 200 billion yuan in 2019, and it is expected to reach nearly 300 billion yuan in 2021.
As the "sentinel" of data collection, sensors also play a very important role in the medical field. Medical sensors integrate various 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 medical sensors, and different types of medical sensors can play different roles in the medical field. Generally speaking, medical sensors have various uses such as detecting biological information, clinical monitoring and controlling the physiological processes of the human body. Guo Meng, secretary general of the Sensitive Components and Sensors Branch of China Electronic Components Industry Association, said in an interview with a reporter from China Electronics News that in the process of fighting against the new crown pneumonia epidemic, medical sensors are used in pathological detection, personnel physiological parameter monitoring, life support. Fields such as systems and environmental control have played an extremely critical role.
According to the working principle, medical sensors can be divided into chemical sensors, biological sensors and physical sensors. NTC temperature sensors belong to the category of physical sensors. This year, NTC temperature sensors have played a very important role in medical equipment in the fight against new coronary pneumonia. For example, the NTC temperature sensor required in the ventilator, due to viral infection, dyspnea 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 capacity, and prevent the alveoli from collapsing, thereby changing ventilation. And ventilation function, to achieve the purpose of assisted 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 sensors such as gas mass flow, pressure, humidity, temperature and magnetism to monitor and control indicators such as airflow, pressure, temperature and humidity, and support and ensure 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, the NTC temperature sensor is not limited to the diagnosis and treatment of the new crown pneumonia epidemic or medical diseases. It can realize the detection of daily health status and escort people's life and health.
