Resistance strain sensor, as early as the late 1930s, shortly after the first strain gauges were made by E.SimmONs and A.C.Ruge in the United States, the adhesive resistance strain sensor was invented in the early 1940s (1944). 
Up to now, it has a history of more than half a century. 
In the meantime, there is a qualitative leap almost every 10 years. 
 
Resistance strain sensor. 
The 1940s and 1950s were the early development stage of the sensor. 
At that time, elastic materials, paper-based wire strain gauges and binders were all in the stage of development and research, and their properties were not perfect. 
Therefore, the accuracy and stability of the resistance strain sensor can not meet the requirements of the measurement technology. 
In the 1950s, after the advent of the foil resistance strain gauge, the temperature characteristics of the strain gauge and the mechanical properties of the binder were improved, the temperature and creep effects of the sensor were obviously suppressed, and the accuracy was improved by about an order of magnitude. 
Foil resistance strain gauge. 
In the mid-1960s, sensors entered the field of measurement. 
In the more than 10 years from the late 1960s to the early 1980s, due to the breakthrough progress made in various technologies closely related to the performance of the sensor, the resistance strain sensor has achieved unprecedented rapid development. 
Force sensor. 
Applied to computer pressure testing. 
After the 1980s, with the technical progress of processing technology and pasting technology, the accuracy and reliability of the sensor have been greatly improved, which has been widely used in the field of measurement technology, and has become an important part of strain electrical measurement technology. 
Now, the sensor has been developed from simply as a conversion element to a multi-functional and intelligent information measurement element. 
In particular, the development of microelectronics and micromechanical technology will bring a broader space for the development of resistance strain sensors. 
Miniature Force Sensor-used in Medical Field. 
High temperature melt pressure sensor. 
High temperature melt pressure sensor is used to measure and control the pressure of high temperature fluid medium in chemical fiber spinning, polyester, rubber and plastic machinery. 
Force weighing sensor. 
The resistance strain force weighing sensor is often called the weighing sensor because it is used in all kinds of electronic weighing instruments, and the one used to measure the experimental load or force is called the force sensor.
