Abstract

The invention discloses a spherical bionic six-axis force sensor. The spherical bionic six-axis force sensor comprises an inner sphere, an outer sphere, a signal conditioning circuit, and six Y beams;the outer sphere is hallow; the inner sphere is arranged inside the outer sphere, and is concentric with the outer sphere; bottom ends of the Y axes are fixedly connected with the inner sphere; two top ends of the Y axes are in close contact with an inner wall of the outer sphere; two strain gauges are arranged at the bottoms of the Y axes, and are symmetrical to each other relative to the Y axes; the inner sphere is fixedly connected with one end of a connecting rod; the signal conditioning circuit is located inside the outer sphere, and is fixedly connected on the connecting rod; and the strain gauges on the six Y axes are in electric connection with the signal conditioning circuit, respectively. The spherical bionic six-axis force sensor disclosed by the invention realizes manual detection on of joint stress.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a spherical bionic six-dimensional force sensor. Background technique [0002] Articular cartilage injury is a common disease. There are many reasons for articular cartilage injury. Once articular cartilage is damaged, joint movement function will be affected. With the intensification of competition confrontation, sports-related joint injuries have an upward trend. In addition, arthritis is a common disease in the elderly after the age of 65, and degenerative osteoarthritis is closely related to age. Clinically, most patients who need joint replacement surgery are elderly patients, and they generally include three types: degenerative joint disease, severe joint damage caused by previous trauma or infection, and patients with bone developmental diseases. Both in terms of quantity and proportion, joint injuries are showing an upward trend, and artificial joint replacement for art...
