Reason.Wherein, it should be noted that in the first friction line options core-spun yarn, the second friction line options conductive fiber material, second
The conductive fiber material of friction line can be identical as the material of Conductive Core in the first friction line, can also be different.
Referring to shown in Fig. 3, in the initial state, together with the first friction line 1 is closely knit with the second friction line 2,
Due to triboelectrification effect, when polyester fiber 7 is contacted with silver-colored conductive fiber 8, the silver-colored meeting of conductive fiber 8 betatopic, polyester fiber 7
Electronics can be obtained, so that 8 surface of silver-colored conductive fiber is positively charged, 7 surface of polyester fiber is negatively charged, in Fig. 3 shown in (a)；When
When applying the force-extension power generation cloth, the first friction line 1 and the second friction line 2 are separated from each other under the drive of resilience axes 3,
Due to electrostatic induction effect, electrons by external circuit from first friction line 1 flow to the second friction line 2, the external circuit in figure with
R signal is loaded, current direction is illustrated with black arrow, to form the electricity for flowing to the first friction line 1 by the second friction line 2
I is flowed, in Fig. 3 shown in (b)；When first friction line 1 with second friction line 2 separate at a distance from reach maximum when, electrons stopping
It flows, at this time no electric current on external circuit (load R), in Fig. 3 shown in (c)；Then, when removing external force, the power generation cloth
It can shrink, to make the first friction line 1 and the second friction line 2 contact with each other under the drive of resilience axes 3, due to electrostatic induction
Effect, electrons flow to the first friction line 1 from the second friction line 2 by external circuit (load R), are rubbed to form one by first
The electric current i that line 1 flows to the second friction line 2 is wiped, in Fig. 3 shown in (d)；When the power generation cloth shrinks back original state completely, such as Fig. 3
In shown in (a), charge inducings all at this time have all been neutralised, therefore do not have electric current on external circuit.Periodically weigh
The multiple above process will generate the electric current output an of alternation on external circuit (load R).
In the present embodiment, stretched using the power generation cloth based on friction nanometer power generator that is somebody's turn to do having a size of 9cm × 4.5cm
The test of electricity output performance is carried out under mode, wherein external force is applied to the power generation cloth using a linear motor and is drawn
It stretches.

Learn output performance figure, wherein Fig. 4 A is to stretch length based on the power generation cloth of friction nanometer power generator according to the embodiment of the present disclosure
Open-circuit voltage V when spending up to 60%OCCurve of output；Fig. 4 B is the power generation according to the embodiment of the present disclosure based on friction nanometer power generator
Short circuit current I of the cloth when tensile elongation is up to 60%SCCurve of output；Fig. 4 C is that friction nanometer is based on according to the embodiment of the present disclosure
The open-circuit voltage V of the power generation cloth of generatorOCAnd short circuit current ISCWith the relation curve of tensile elongation.
From Fig. 4 A-4C: there are positives with tensile elongation for electricity output performance of the power generation cloth under stretch mode
It closes；In the range of elongation strain are as follows: when 10%~100%, open-circuit voltage are as follows: 0.7V~3.5V；Short circuit current are as follows: 0.2nA~
3nA.When tensile elongation is 60%, the open-circuit voltage V of the power generation clothOCFor 2V, as shown in Figure 4 A, short circuit current ISCFor
2nA, as shown in Figure 4 B, open-circuit voltage VOCAnd short circuit current ISCIt is positively correlated with tensile elongation, wherein short circuit current ISC
It is more preferable with the linearity of tensile elongation, as shown in Figure 4 C.
Under contact-clastotype, by the power generation cloth and other objects: cloth, skin, ground etc. are mutually rubbed
It wipes, due to triboelectrification and electrostatic induction effect, the electric current of an alternation can be generated in the load.Fig. 5 is according to disclosure reality
Apply working principle diagram of the example based on the power generation cloth of friction nanometer power generator under contact-clastotype.In the present embodiment, selection

The material of Conductive Core is identical, can also be different.
Referring to Figure 5, extraneous frictional layer 9 is completely attached to the power generation cloth, it is assumed that the two is all not charged in advance, by
In triboelectrification effect, when terylene 7 is contacted with the cotton as extraneous frictional layer 9, cotton meeting betatopic, terylene 7 can obtain electric
Son；And when silver fiber 8 and cotton contact, silver fiber 8 can betatopic, cotton 9 can obtain electronics, therefore in the first friction line 1, the
The distribution of charges as shown in (a) in Fig. 5 is generated on two friction lines 2 and extraneous frictional layer 9；When extraneous frictional layer 9 is in external force
When the lower beginning of driving is separated with the power generation cloth, due to electrostatic induction effect, electrons are flowed by external circuit from the first friction line 1
To the second friction line 2, the external circuit in figure to load R signal, illustrated with black arrow by current direction, to form one by the
Two friction lines 2 flow to the electric current i of the first friction line 1, in Fig. 5 shown in (b)；When extraneous frictional layer 9 and the power generation cloth separate
Distance when reaching maximum, electrons stop flowing, at this time no electric current on external circuit (load R), in Fig. 5 shown in (c)；With
Afterwards, when close to the power generation cloth again under the driving of external force when extraneous frictional layer 9, due to electrostatic induction effect, electronics
The first friction line 1 can be flowed back to from the second friction line 2 by external circuit (load R), form one and flow to the from the first friction electrode 1
The electric current i of two friction electrodes 2, in Fig. 5 shown in (d)；When extraneous frictional layer 9 and the power generation cloth are another under the driving of outer power
When secondary full contact, in Fig. 5 shown in (a), charge inducings all at this time have all been neutralised, therefore external circuit is (negative
Carry R) on no electric current.It is repeated periodically the above process, the electric current that an alternation will be generated on external circuit (load R) is defeated
