Sensors become the key weapon in the information age

The sensor is a detection device that can transform the detected information into electrical signals or other desired forms of information output in accordance with certain laws to meet the requirements of information transmission, processing, storage, display, recording and control.

It is the first link to achieve automatic detection and automatic control. In order to obtain information from the outside world, people must rely on sensory organs. And relying solely on people’s own sensory organs, their function in the study of natural phenomena and laws and production activities is far from enough. Therefore, it can be said that the sensor is an extension of human features, also known as electrical features. A few days ago, engineers at the University of California, Berkeley, used a flexible and flexible plastic to create a thin electronic skin for the first time. When it was touched, it immediately glowed. The result is expected to make the robot have a more realistic touch; Murata Manufacturing Co., Ltd. (China) ) announced that it will force the MEMS sensor market; Apple also showed its interest in the 3D sensor business.

With the advent of the information age, sensors have become the main means and means for people to obtain information in the fields of nature and production. In modern industrial production, especially in the automated production process, various sensors are used to monitor and control various parameters in the production process so that the equipment operates in a normal state or an optimal state, and the products achieve the best quality; in the basic discipline In the study, the sensor has a more prominent position. Today, sensors have already penetrated into an extremely wide range of fields such as industrial production, space development, ocean exploration, environmental protection, resource investigation, medical diagnosis, biological engineering, and even cultural relic protection. It can be seen that the important role of sensor technology in economic development and social progress is very obvious. Statistics show that the annual revenue of the global smart sensor market will increase at a rate of 10% per year and reach US$6.9 billion by 2018. At present, there are 65 million sensor devices installed worldwide with processors. By 2019, this number will reach 2.8 trillion.
