Abstract
The sensor can simultaneously detect the force value information of three dimensions in the three-dimensional space. With the progress of science and technology and the development of the Internet, the sensor is widely used in many fields such as medical rehabilitation and aerospace. The three-dimensional force sensor based on the measuring principle of resistance strain gauge, capacitance type and piezoelectric type is introduced. Because of its advantages of high precision, mature technology and wide measuring range, the three-dimensional force sensor becomes the most mature kind of sensor. At present, the main goal of the elastomer design of the sensor is to improve the measurement accuracy of the sensor and reduce the coupling error between dimensions. Finally, the development trend of the three-dimensional force sensor is prospected based on the research and application status of the three-dimensional force sensor.
