Abstract

The invention discloses a sensor for measuring occlusal force, which belongs to the force sensor. The sensor comprises a fixed area of an elastomer structure, a patch area and an occlusion area, wherein the patch area comprises a patch area for measuring the occlusal force of an upper jaw and a patch area for measuring the occlusal force of a lower jaw, both the patch area for measuring the occlusal force of the upper jaw and the patch area for measuring the occlusal force of the lower jaw are respectively and fixedly provided with a plurality of strain gauges, the elastomer structure is also provided with a through hole, and both the patch area for measuring the occlusal force of the upper jaw and the patch area for measuring the occlusal force of the lower jaw are respectively arranged on the edge of the through hole; the elastomer structure of the sensor is provided with the through hole, and two groups of strain gauges are arranged on two sides of the through hole to form a Wheatstone bridge, so that the measurement precision and sensitivity of the sensor can be effectively improved; moreover, the two Wheatstone bridges are simultaneously accessed to a sensing signal receiving device through a junction terminal, so that the measurement performance of the sensor in use is stable. Meanwhile, the sensor is simple in structure, easy to manufacture and high in sensitivity.

Description

[0001] technical field [0002] The present invention relates to a force sensor, and more particularly, the present invention generally relates to a sensor for measuring bite force. [0003] Background technique [0004] The bite force is the chewing pressure generated by the muscles when the upper and lower teeth are in contact. This force is transmitted from the teeth to the periodontal tissue and then to the jawbone. Generally calculated in kg. The bite force of different animals varies greatly, even the same animal has different bite force in different periods, such as: the bite force of a common tiger is 499kg, the bite force of a lion is 454kg, the bite force of a wolf is 318kg, etc. . In the early 1980s, Israeli Arcan and American Azndman invented the optical occlusal method, and the optical occlusal film and optical occlusion instrument were produced by the American Vishay Company, which can conduct semi-definite quantitative analysis of occlusal contact. Combini...
