The development direction of sensors
(1) Development towards high precision: With the continuous improvement of the degree of automated production, the requirements for sensors are also increasing. It is necessary to develop new sensors with high sensitivity, fast response speed and good interchangeability to ensure the reliability of production automation Sex. Recently, few manufacturers can produce sensors with an accuracy of more than one ten thousandth, and their output is far from meeting the requirements.
(2) Development towards high reliability and wide temperature range: The reliability of sensors directly affects the anti-interference performance of electronic equipment, and the development of sensors with high reliability and wide temperature ranges will be a good direction. Increasing the temperature range has always been a major issue. Most sensors have a working range of -20°C to 70°C, while automotive boilers and other occasions require the sensor to work at -20°C to 120°C. The temperature requirements of the sensor are higher in smelting, coking, etc , So the development of sensors for emerging materials (such as ceramics) will be very promising
(3) Development towards miniaturization: The functions of various control instruments and equipment are becoming more and more people. It is required that the volume of each component can occupy as small as possible. Therefore, the volume of the sensor itself is also as small as possible. This requires the development of new materials and Processing technology, the volume of sensors made of silicon materials is already very small. For example, traditional acceleration sensors are made of gravity blocks and springs, which are large in size, poor in stability, and short in life. However, silicon acceleration sensors made of various micro processing technologies such as lasers are very small in size and reliable in interchangeability. Good sex
(4) Development towards micro-power consumption and passivity: Sensors generally convert from non-electricity to electricity. They cannot be separated from the power supply during five operations. In the field or far away from the power grid, they are often powered by batteries or solar power. The development of micro-power sensors and passive sensors is an inevitable development direction, which can save energy and increase system life. At present, chips with low power loss are developing rapidly, such as the T12702 operational amplifier, which consumes 1.5mW of energy, while the working voltage is only 2-5V.
