Abstract

The invention discloses a spherical bionic six-dimensional force sensor, comprising an inner ball, an outer ball, a signal conditioning circuit and six Y-shaped beams, the outer ball is hollow, and the inner ball is arranged inside the outer ball and connected with the outer ball The outer ball is concentric, the bottom end of the Y-shaped beam is fixedly connected to the inner ball, the two top ends of the Y-shaped beam are attached to the inner wall of the outer ball, and the bottom of the Y-shaped beam is provided with Two strain gauges, and the two strain gauges are symmetrical about the corresponding Y-shaped beam, the inner ball is fixedly connected to one end of the connecting rod, the signal conditioning circuit is located in the outer ball and fixed on the On the connecting rod, the strain gauges on the six Y-beams are respectively electrically connected to the signal conditioning circuit. The spherical bionic six-dimensional force sensor of the present invention realizes manual detection of joint force.

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...
