Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is explained further details.
Referring to Fig. 1, a kind of intelligent clothing that is used for the vibrational energy collection comprises fabric 101, goes back involving vibrations energy acquisition material 102, energy storage units 103 and energy management unit 104; Said vibrational energy capturing material 102 is attached to the outer surface of fabric 101, and said vibrational energy capturing material 102, energy storage units 103 and energy management unit 104 are electrically connected successively; Said vibrational energy capturing material 102 is through piezoelectricity mode collecting energy; Be used to gather the vibrational energy that ambient vibration or object of which movement produce; The vibrational energy that collects is stored by energy storage units 103; Pass through the control out-put supply of energy management unit 104 at last, and to external electronic product power supply.
Vibration source 100 is the vibration of external environment condition or the motion of intelligent clothing wearer; When vibration source 100 acts on garment material 101; Can make fabric 101 produce deformation such as stretching, compression, distortion, bending and fold; Piezoelectric material film layer 1022 can convert this deformation into the electric energy of alternating voltage form through direct piezoelectric effect; And pass through conductive layer 1023 with this electric energy importing energy storage units 103, wherein the rectification circuit 1031 in the energy storage units 103 converts the alternating voltage of gathering into the unipolarity d. c. voltage signal, utilizes big electric capacity homenergic memory device stores electric energy through memory circuit 1032 again.Then energy management unit 104 can be controlled and export institute's storage of electrical energy, and its detailed process is following: as
When external connected electronic product 105 needs electric energy to supply with; Energy storage units 103 release voltages; At this moment the booster circuit 1041 of energy management unit 104 can make release voltage raise; Keep the stable of output voltages through voltage stabilizing circuit 1042 again, through external tapping circuit 1043 voltage is exported 105 uses of sub-product of supplying power from intelligent clothing at last.
Referring to shown in Figure 2, said energy acquisition material 102 is made up of boundary layer 1021, piezoelectric material film layer 1022, conductive layer 1023 and encapsulated layer 1024 outside being reached by the lining.Because the general fluffy or crinosity in fabric 101 surface, need be between fabric 101 and piezoelectric material film layer 1022 increase one deck smooth surfaces boundary layer 1021, so that smooth seal to be provided
The brush surface; Piezoelectric material film layer 1022 usefulness piezoelectric are printed slurry through half tone and ink jet printing preparation, and this layer can convert the deformation of dress materials into electric energy; The electric energy that conductive layer 1023 is gathered the piezoelectric material film layer imports energy storage unit 103, provides electricity interconnected effect; And the layers of material under 1024 pairs of top layers of encapsulated layer plays protection.
This intelligent clothing is owing to the restriction of yarn fabric lining to temperature, and its thin layer that requires to deposit solidifies under low temperature (like 150 degree) environment, thus the nano powder material of employing macromolecular material or curing under low temperature (like 150 degree) or ultraviolet light among the present invention; Consider the demand in the real life in addition, the boundary layer 1021 and the encapsulated layer 1024 of employing also has waterproof, anti-effect of cleaning.
In addition, the described piezoelectric that is used for this intelligent clothing is printed slurry, but it is powdery shape screen painting and ink jet inks, is the basis with " soft " plumbous zirconate titanate (PZT); This powder mixes with multiple polymers, adhesive and additive, to reach the optimum performance of piezoelectric activity material, keeps impressionability preferably simultaneously, and wherein alternative polymer comprises polyurethane and silicon rubber etc.; For piezoelectric print starch wherein molecule requirement can not be excessive, prevent to block the nozzle of printing machine.
Described each layer (boundary layer, piezoelectric thin film layer, conductive layer and encapsulated layer), the form that all can print slurry or ink is used for screen painting and ink jet printing.The typography that is adopted mainly solves following technical problem: the flexibility that 1, has reduced cost and printing is higher, but computer control forms various figures etc., in reality, has more practicality; 2, two kinds of typographies have satisfied the requirement of most of printable material; For example: the printing of screen painting slurry (China ink or paste) need will be between the 150cP to 250cP for (viscosity changes with the variation of shear pressure) and the viscosity of thixotropic; And it is constant to print slurry (China ink or paste) viscosity in the ink jet printing, and numerical value is between 15cP to 25cP; Both combinations provide the characteristic that (China ink or paste) starched in a large amount of printings that suits thus.Different processes provides different printing effects simultaneously; For example to the film thickness resolution of described each layer (boundary layer, piezoelectric thin film layer, conductive layer, encapsulated layer); The resolution that screen painting can reach is limited in about 100 μ m usually; And not similarly restriction of ink jet printing, it is operated in other resolution of submicron order altogether.Through will satisfy the preparation of different thin layers to the selection of two kinds of typographies.
This is bright to have solved the problem that the conventional batteries power supply is long-term or continuation is supplied with, and has solved the pollution problem of conventional batteries to environment simultaneously, and the selection of flexible material is better to the selectivity of ambient vibration frequency with preparation;, and can not receive the restriction on direction of vibration of environment or object, the energy of therefore gathering is more considerable; The piezoelectric material film layer utilizes piezoelectric to print slurry and forms through half tone and ink-jet technology printing; Because of its technology cost is low, can make in batches, have a wide range of applications.
Explanation is at last; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although with reference to preferred embodiment the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention; And not breaking away from the aim and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
