The specific implementation of double-layer wave shape hybridized nanometer generator of the present invention is discussed in detail with reference to the accompanying drawings and examples
Mode.
Embodiment one：
Referring to Fig. 1, double-layer wave shape hybridized nanometer generator includes upper plastic-substrates 101, middle plastic-substrates 109, lower modeling
Expect substrate 117, two panels wave flexible plastic sheet 105 and 113 includes the electrode layer the 106, the 6th of the second electrode lay 104 and the 3rd respectively
The electrode layer 114 of electrode layer 112 and the 7th.
Upper plastic-substrates 101, middle plastic-substrates 109, lower plastic-substrates 117 have certain mechanical strength and thickness, two panels
Wave flexible plastic sheet is placed between three matrixes, forms double-layer wave shape hybridized nanometer generator；Wherein, wave elastoplast
The positive and negative of piece 105 is provided with the second electrode lay 104, the 3rd electrode layer 106, has the 6th electrode on wave flexible plastic sheet 113
The 112, the 7th electrode layer 114 of layer, these serve as contact electrode layer.When generator is acted on (effect of vibration) by external force so that miscellaneous
Change the up-down vibration of plastic-substrates 109 in nano generator, drive the up-down vibration of permanent magnet 119, make the first of generator unit to rub
Effective contact area increase of layer 103 and the second electrode lay 104 reduces, between first electrode layer 102 and the second electrode lay 104
There is pulse electrical signal output.The magnetic flux of coil 118 and 120 in upper plastic-substrates 101 and lower plastic-substrates 117 is also because magnetic
The up-down vibration of iron 119 and change, thus also have output of pulse signal.
The double-layer wave shape hybridized nanometer generator of the present invention make use of the friction layer material with differentiated friction electrode sequence
The principle of surface charge transfer occurs during contact.Heretofore described " friction electrode sequence ", refers to according to material to electric charge
The sequence that attraction degree is carried out, two kinds of materials are in the moment to contact with each other, and positive charge is from friction electrode sequence on the contact surface
The more negative material surface of middle polarity is transferred to the material surface of polarity calibration in friction electrode sequence.So far, also without one kind
Unified theory can completely explain the mechanism of electric charge transfer, it is considered that, the surface work content of this electric charge transfer and material
Number is related, and electric charge transfer is realized by the transfer of electronics or ion on the contact surface.It should be noted that friction electrode sequence
A kind of simply statistical result based on experience, i.e. two kinds of materials differ more remote in the sequence, and produced electric charge is being just after contact
The probability that negativity and the sequence are consistent is bigger, and actual result is affected by various factors, such as material surface
Roughness, ambient humidity and whether there is Relative friction etc..The inventors discovered that if two kinds of materials are in the electrode sequence that rubs
The position being closer to, the positive negativity of distribution of charges and may not meet the prediction of the sequence after contact.Needing further explanation is,
The transfer of electric charge does not simultaneously need the Relative friction between two kinds of materials, simply by the presence of contacting with each other, therefore, from stricti jurise
On say, the statement of friction electrode sequence is inaccurate, but is used till today always due to historical reasons.
Heretofore described " contact electric charge ", refer to contacting in the material that two kinds of friction electrode sequence polarity have differences
And the electric charge that its surface is carried after separating, it is considered that, the electric charge is only distributed in the surface of material, and distribution depth capacity is only
About 10 nanometers.Research finds that the electric charge can keep longer time, according to the factors such as humidity in environment, its retention time
A couple of days is even up in a few hours, and its quantity of electric charge to disappear can be supplemented by contacting again, therefore, the present inventor
Think, the electricity of contact electric charge, which can be approximately considered, in the present invention keeps constant.It should be noted that the symbol of contact electric charge
It is the symbol of net charge, i.e., the accumulation regions of negative electrical charge is there may be in some areas of the material surface with positive contact electric charge
Domain, but the symbol of whole surface net charge is just.
In the generator of the present invention, the material selection of the first frictional layer and the second electrode lay, as long as meeting：First frictional layer
Friction electrode sequence difference be present with second electrode layer material in material.The generator of the present invention is equivalent to first electrode layer 102, first
Frictional layer 103 and the second electrode lay 104 form friction nanometer generating unit；
Include in the electromagnetic unit that coil is formed with permanent magnet：Coil 118 and insertion in insertion in plastic-substrates 101
Permanent magnet 119 in middle plastic-substrates 109 forms the first Electromagnetic generation unit：Permanent magnet in insertion in plastic-substrates 109 and
Coil 120 in embedded lower plastic-substrates 117 constitutes the second Electromagnetic generation unit；The up and down motion of permanent magnet causes to pass through line
Enclose the structure of magnetic flux change.
Four friction nanometer power generators and two electromagnetic generators that the generator of the present invention includes can pass through external circuit
Integrated, higher power output can be obtained.
The first described friction nanometer generating cell operation principle explanation：First frictional layer 103 and the second electrode lay 104 are
2 kinds of materials that friction electrode sequence difference be present, in the state of outer masterpiece use, wave flexible plastic sheet is compressed, the first frictional layer
103 and 104 effective contact area of the second electrode lay increase, so contact when occur surface charge transfer, formed layer of surface
Contact electric charge.Because position of the material in the electrode sequence that rubs of the first frictional layer 103 and the second electrode lay 104 is different, second
The surface of electrode layer 104 produces positive charge, and the surface of the first frictional layer 103 produces negative electrical charge, and the electricity size of two kinds of electric charges is identical,
Therefore there is no electrical potential difference between first electrode layer 102 and the second electrode lay 104, just flowed without electric charge yet.Plastics in then
Substrate 109 moves downward, the stretching of wave flexible plastic sheet, the contact area between the first frictional layer 103 and the second electrode lay 104
It is gradually reduced, the entirety being now made up of first electrode layer 102 and frictional layer 102 has remains negative electrical charge only, and second electrode
Layer 104 has surplus positive charge, therefore generate electrical potential difference between first electrode layer 102 and the second electrode lay 104 only.For balance
The electrical potential difference, electronics flow into first electrode layer 102 by external wire by the second electrode lay 104, so as to external circuit produce by
First electrode layer does not have potential to the transient current of the second electrode lay between first electrode layer 102 and the second electrode lay 104
Difference, also just produced in external circuit without electric current.Central upper plastic-substrates 101 are moved upwards, due to the first frictional layer 103 and second
Effective contact area of electrode layer 104 becomes big, and the negative electrical charge on the surface of the second electrode lay 104 is to negative electrical charge in first electrode layer 102
Repulsive interaction enhancing, thus cause the electrical potential difference between first electrode layer 102 and the second electrode lay 104 to reduce.To be further
The electrical potential difference is balanced, electronics flows into the second electrode lay 104 by external circuit by first electrode layer 102, so as to be produced in external circuit
With transient current in opposite direction for the first time.When wave flexible plastic sheet is extruded completely, make the first frictional layer 103 and the second electricity
After pole layer 104 is in contact, the situation of previous step is repeated.As can be seen here, when external force (effect of vibration) acts on double-layer wave
During shape hybridized nanometer generator, effective contact area increase can be promoted to reduce, pass through the first frictional layer 103 and the second electrode lay
Two processes of continuous increase and reduction of effective contact area, produce pulse current in opposite direction, realize respectively between 104
Pulse between first electrode layer 102 and the second electrode lay 104 generates electricity.
