Description
Technical Field
The invention belongs to the field of structural health monitoring, and particularly relates to a structural deformation monitoring adhesive tape based on triboelectricity generation.
Background
The thermal expansion and cold contraction caused by temperature fluctuation and various loads generated by stress of the structure have important influence on the stability and durability of mechanical equipment and infrastructure, and the adverse loads can cause large deformation, cracks, damage and other adverse consequences of the structure, so that the normal use of the mechanical equipment or the service life of the infrastructure is influenced. In recent years, researchers have conducted a series of researches on structural health monitoring in order to improve the stability and durability of mechanical equipment and infrastructure and reduce economic loss and casualties caused by equipment destruction. The structure health monitoring technology is an important application of an intelligent material structure in practical engineering, and the structure health monitoring system is a bionic intelligent system and can monitor the health state of the structure on line. The embedded or surface-adhered sensor is used as a nervous system, and can sensitively sense and forecast the damage and defects in the structure. When the structure is in a non-healthy state, non-healthy information can be transmitted to the signal receiving device in time, and relevant managers can react according to the situation after receiving the signals. At present, the structural health detection technology is developed at a high speed, and researchers mainly design structural health monitoring equipment in the directions of safety, economy, simplification, energy conservation, high efficiency and the like.
Triboelectric and electrostatic phenomena are very common phenomena, widely existing in every aspect of daily life, but are often an energy form overlooked by people because they are difficult to collect and utilize. Researchers believe that if the electric energy generated by friction can be collected by a new method or the method is used for converting irregular kinetic energy in daily life into usable electric energy, the method has important influence on the fields of structural health monitoring technology and energy supply. Researchers have developed electrostatic microgenerators and have found widespread use in the field of microelectromechanical. However, the design of the micro-electrostatic generator is mainly based on inorganic silicon materials, and the manufacture of the device requires complicated processes and precise operations. The preparation of the whole device needs large-scale instruments and special production conditions, and the manufacturing cost is too high, so that the commercialization and daily application of the generator are not facilitated. Recently, research and development teams successfully develop a flexible triboelectric generator and a transparent triboelectric generator and high-performance pressure sensor based on the principle by utilizing the principle of triboelectrification and electrostatic induction, and the novel device is more suitable for the field of structural health monitoring.

In the above structure, an analog-to-digital converter, a microcontroller and an arithmetic unit are provided in the electric signal receiving device 3.
As an optimization: the adhesive tape main body 2 further comprises an outer adhesive layer 10 adhered to the outer side of the outer protective film 4b, the lead 9 is fixed to the outer side of the outer protective film 4b through the outer adhesive layer 10, and the outer adhesive layer 10 can be torn off when the adhesive tape main body is used, so that the lead 9 is exposed.
As an optimization: the inner protective film 4a and the outer protective film 4b are connected at two ends in the width direction, so that the inner electrode 8a, the inner friction charge generation material film, the outer friction charge generation material film and the outer electrode 8b are all coated between the inner protective film 4a and the outer protective film 4 b.
In the above structure, the inner protective film 4a and the outer protective film 4b are connected at both ends in the width direction by pressure welding or adhesion.
As an optimization: the inner protective film 4a and the outer protective film 4b have elasticity.

The design and manufacturing requirements of the structural deformation monitoring adhesive tape based on triboelectricity generation are explained by taking fig. 1 and 2 as examples. Twine a plurality of circles of sticky tape main part 2 on the sticky tape skeleton 1 shown in figure 1, and sticky tape main part 2 can be divided into a plurality of sections fixed length person of facilitating the use intercepting in the manufacturing process by the design, thereby each section sticky tape all is furnished with two wires 9 and inserts outside signal of telecommunication receiving arrangement 3 at the during operation, two wires 9 respectively one end connect corresponding electrode, the other end is drawn out and is settled on outermost protective film 4b surface through outer glue film 10, tear outer glue film 10 during the use, the wire 9 that will expose again inserts signal of telecommunication receiving arrangement 3. As shown in fig. 2, the radial multilayer structure of the adhesive tape main body is installed in the order from outside to inside: the two ends of the outer protective film 4b and the inner protective film 4b along the width direction are pressed or jointed together, a space is left between the two ends for arranging the triboelectric anode material film 5 and the triboelectric cathode material film 6, the triboelectric anode material film 5 and the triboelectric cathode material film 6 need to be tightly jointed, and when the structure is deformed, the two films generate electricity by friction to generate an obvious electric signal. The innermost layer of the multilayer structure is an inner glue layer 7, the inner glue layer 7 is convenient for the adhesive tape main body 2 to be continuously wound on the adhesive tape framework 1 for multiple circles, and is also convenient for the adhesive tape main body 2 to be adhered or wound on the surfaces of various structures.
The working mechanism of the structural deformation monitoring tape based on triboelectric charging is explained by taking fig. 3 and 4 as an example. For example: as shown in fig. 4, the tape body 2 may be cut into several pieces and wound around a structure such as a circular tube, or may be adhered to the surface of the structure to be monitored along the direction of the axis of the circular tube. When the tape-applied and wound portion is not deformed, the tape is in an initial state shown in the upper part of fig. 3. When the round pipe wound and attached by the adhesive tape is expanded with heat and contracted with cold or the hydraulic pressure in the pipe is too high, the round pipe can deform along the radial direction, and the pipe diameter can be increased or reduced; the circular tube may also be deformed axially or have protrusions and depressions on the surface. Taking the pipe diameter becoming larger as an example: when the pipe diameter is increased, the circumference of the circular pipe is also increased, the adhesive tape wound and adhered on the pipe wall of the circular pipe can generate the deformation condition shown in the lower left part of fig. 3, the triboelectric cathode material film 6 close to the inside can be extruded to the triboelectric anode material film 5 at the outer side along with the increase of the pipe diameter, meanwhile, the triboelectric cathode material film 6 can be elongated to generate tangential displacement due to the increase of the pipe circumference, so that the triboelectric anode material film 5 and the triboelectric cathode material film 6 can generate relative displacement to generate triboelectric electricity, electrons generated by the friction are finally transmitted to the external electric signal receiving device 3 through the electrodes plated on the two films and the lead 9 to form a closed loop, the electric signal receiving device 3 can judge the deformation degree of the structure according to the transmitted electric signals, and therefore, the whole-period structural health monitoring is realized. Similarly, when the surface of the axially adhered adhesive tape is concave or convex, the adhesive tape may deform as shown in the lower right part of fig. 3, and the two films may be relatively displaced to generate friction electricity, so as to monitor the axial extension and contraction of the structure and abnormal convex or concave conditions.
The triboelectric anode material film 5 in the present invention is specifically made of polyethylene terephthalate (PET), and the triboelectric cathode material film 6 is specifically made of polyimide (Kapton). The triboelectric anodic material film 5 can also be made of nylon, and correspondingly, the triboelectric cathodic material film 6 is made of polytetrafluoroethylene.
