Sensors located in the forefront of information systems, whose performance and reliability of output information is essential for the quality of the information system. Sensor technology rapidly bound to the rapid development of science and technology, changes in the human environment and to the future expansion of space play a decisive role.
The sensors now more widely used in the practical engineering application, the basic components of sensors:sensitive components、conversion components、measuring circuit. Mainly used to measure pressure, gravity, displacement, strain, torque and so on. The classification of sensors is no uniform method, different scientific and technological fields and different industries,the hundreds of thousands of sensors of classified has always been a science. Scientifically and correctly classified depends on the extent and level of sensor knowledge. This paper presents the design of resistance strain sensor and processing technology, through the change of resistance parameters by non-electricity measuring electricity.
