Shower head type inter-dimensional decoupling two-dimensional wireless passive sensor

Abstract

The present invention discloses a shower head type inter-dimensional decoupling two-dimensional wireless passive sensor, comprising a sensor bearing joint, an upper supporting cylinder, an upper showerhead rigid structure body, a rigid connecting circular plate, a curved rectangular bearing body, a curved rectangular variable ring, a lower showerhead rigid structure body, a torque deformation structure body, a curved rectangular transmission rod and a sensor bearing shaft. The shower head type inter-dimensional decoupling two-dimensional wireless passive sensor can simultaneously detect bending force component and torsion force component in coupling force, namely, structurally decouple the coupling force; does not need to be connected to a power supply line or collect data through a cableinterface; and can be applied in the medical field, and to streams of human implanted sensors, and greatly reduces steps for wire embedding or secondary surgery in a human body after the sensor is implanted into the human body.

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a shower head type inter-dimensional decoupling two-dimensional wireless passive sensor. Background technique [0002] A sensor is a device and device that can sense a specified measured value and convert it into a usable signal according to a certain rule, usually consisting of a sensitive element and an elastic element. Multidimensional force sensor is a force sensor that can measure force and moment information in more than two directions at the same time, and is widely used in robotics, bioengineering, industrial manufacturing, medical and health and other fields. [0003] At present, two-dimensional and even multi-dimensional force sensors are mainly divided into resistance strain type, piezoelectric type and capacitive force sensor, which are simple in structure, sensitive and high in precision. The structure of the sensor is to paste or install the strain-sensitive elemen...

Problems solved by technology

[0004] However, when the sensor is subjected to the combination of torsional stress and bending stress, the sensor in the prior art often compensates and decouples the strain gauges by forming a bridge, and the mechanical structure does not have the ability to decouple the torsional stress and the bending stress.

[0005] Existing two-dimensional / multi-dimensional sensors, because wires must be used to connect strain gauges, even if radio is used for information transmission, but the battery contains limited power, it is difficult to achieve long-term dynamic monitoring
