Two-dimensional wireless passive implantable sensor with helical dimension decoupling

Abstract

The present invention discloses a spiral inter-dimension decoupling two-dimensional wireless and passive implantable sensor. The sensor comprises a tension and pressure shaft, a reverse the expansionshaft, a sliding shaft, a spacing end cap, an axial deformation ring, an upper deformation ring, a lower deformation ring and a support pillar; when the spiral inter-dimension decoupling two-dimensional wireless and passive implantable sensor is used, when the axial force is coupled with a torsional force, the coupled axial force and torsional force allow the axial deformation ring to generate stress and allow the upper deformation ring and the lower deformation ring to generate stress to allow magnetostriction materials to generate stress, generate an inverse effect under the effect of applying of an excitation magnetic field and detect the change of the magnetic field through a detection coil so as to solve the problem that a current mechanical structure sensor is difficult to perform component solution of the tension or the pressure and the torsional force through measurement for a coupling force between the tension or the pressure and the torsional force.

Description

technical field [0001] The invention relates to a two-dimensional wireless passive implantable sensor decoupling between spiral dimensions, which belongs to the field of multi-dimensional structure sensors. Background technique [0002] When measuring force, since tension or pressure is often coupled with torsional force, it is difficult to solve the mechanical component between tension or compression and torsion with a single sensor structure. [0003] Most of the mechanical sensors at this stage need to be connected to a power supply and transmit measurement data by wire. This kind of sensor is difficult to apply to the application direction of medical human implantation. [0004] Medical sensors implanted in the human body need to have high battery life and low energy consumption, so as to minimize the medical trauma caused by the installation and battery life of the human body. Contents of the invention [0005] The purpose of the present invention is to provide a two...
