Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further details.
See Fig. 1, a kind of intelligent clothing gathered for vibrational energy, comprises fabric 101, goes back involving vibrations energy acquisition material 102, energy storage units 103 and energy management unit 104; Described vibrational energy capturing material 102 is attached to the outer surface of fabric 101, and described vibrational energy capturing material 102, energy storage units 103 and energy management unit 104 are electrically connected successively; Described vibrational energy capturing material 102 is by piezo electrics collecting energy, for gathering the vibrational energy that ambient vibration or object of which movement produce, the vibrational energy collected is stored by energy storage units 103, finally by the control out-put supply of energy management unit 104, and external electronic product is powered.
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, fabric 101 can be made to produce stretch, compression, distortion, the deformation such as bending and fold, this deformation can be converted to the electric energy of alternating voltage form by direct piezoelectric effect by piezoelectric material film layer 1022, and by conductive layer 1023, this electric energy is imported energy storage units 103, the alternating voltage of collection is converted to unipolarity d. c. voltage signal by the rectification circuit 1031 wherein in energy storage units 103, bulky capacitor homenergic memory device storage of electrical energy is utilized again by memory circuit 1032.Then energy management unit 104 can control institute's storage of electrical energy and export, and its detailed process is as follows: when having
When external connected electronic product 105 needs electric energy to supply, energy storage units 103 release voltage, at this moment the booster circuit 1041 of energy management unit 104 can make release voltage raise, the stable of output voltage is kept again by voltage stabilizing circuit 1042, exported from intelligent clothing by voltage finally by external tapping circuit 1043, supplied for electronic product 105 used.
Shown in Figure 2, described energy acquisition material 102 is by inner and be made up of boundary layer 1021, piezoelectric material film layer 1022, conductive layer 1023 and encapsulated layer 1024 outward.Due to fabric 101 surface generally fluffy or crinosity, need the boundary layer 1021 of 1022 increase one deck smooth surfaces between fabric 101 and piezoelectric material film layer, to provide smooth print
Brush surface; Piezoelectric material film layer 1022 piezoelectric prints slurry by half tone and ink jet printing preparation, and the deformation of dress materials can be converted to electric energy by this layer; The electric energy that piezoelectric material film layer gathers by conductive layer 1023 imports energy storage unit 103, provides the effect that electricity is interconnected; And the layers of material under encapsulated layer 1024 pairs of top layers plays protection.
This intelligent clothing is because fabric is to the restriction of temperature, it requires that the thin layer of deposition solidifies under low temperature (as 150 degree) environment, the nano powder material adopting macromolecular material thus in the present invention or solidify under low temperature (as 150 degree) or ultraviolet light; In addition consider the demand in real life, boundary layer 1021 and the encapsulated layer 1024 of employing also have the effect of waterproof, anti-cleaning.
In addition, described print slurry for the piezoelectric in this intelligent clothing, its for powdery shape can screen painting and ink jet inks, based on " soft " plumbous zirconate titanate (PZT); This powder mixes with multiple polymers, adhesive and additive, and to reach the optimum performance of piezoelectric active material, keep good impressionability, wherein alternative polymer comprises polyurethane and silicon rubber etc. simultaneously; Starching wherein molecule requirement for piezoelectric printing can not be excessive, prevents the nozzle blocking printing machine.
Described each layer (boundary layer, piezoelectric thin film layer, conductive layer and encapsulated layer), the form of slurry or ink that all can print is for screen painting and ink jet printing.The typography adopted mainly solves following technical problem: 1, reduce cost and printing flexibility higher, various figures etc. can be formed by conputer controlled, in reality, have more practicality; 2, two kinds of typographies meet the requirement of most of printable material, such as: the printing of screen painting slurry (ink or paste) needs (viscosity changes with the change of shear pressure) for thixotropic and viscosity will between 150cP to 250cP, and it is constant to print slurry (ink or paste) viscosity in ink jet printing, numerical value is between 15cP to 25cP; Both combinations provide the characteristic of a large amount of printing be suitable for slurries (ink or paste) thus.Different technique provides different printing effects simultaneously, such as 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 μm usually, and the restriction that ink jet printing is not similar, it is operated in other resolution of submicron order altogether.By to the selection of two kinds of typographies by the preparation of satisfied different thin layer.
This is bright solves the problem of the long-term or continuation supply of conventional battery sources, solve the pollution problem of conventional batteries to environment simultaneously, the selection of flexible material is better to the selectivity of environmental vibration frequency with preparation,, and environment or the restriction of object on direction of vibration can not be subject to, the energy therefore gathered is more considerable, piezoelectric material film layer is utilized piezoelectric to print slurry and is formed by half tone and ink-jet technology printing, because its process costs is low, can batch micro operations, have a wide range of applications.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
