Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.Should
Understanding, specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 4, every 10s with wet Cotton Gossypii near shoe pad once, permissible from the signal waveform shape obtained
It is evident that the Unordered system of this shoe pad is the sensitiveest, and stability and repeatability are also very good.Permissible
The change of sensitive collection humiture is also converted into the signal of telecommunication.
Concrete implementation process is: when user is not engaged in motion or under general situation, the shoe pad of shoe lining
Humidity is general, and the resistance value of Graphene flexible electronic skin is less, humiture collection unit during input current
Magnitude of voltage is less, and this magnitude of voltage is input to have arranged in the voltage comparator of threshold voltage, due to input electricity
Pressure is less than set threshold voltage, output low level.Thus the computing substantially not having voltage to be input to below is put
In big device, from without the resistance wire of shoe pad is heated, it is now under general situation；Work as user
When being engaged in motion, the shoe pad temperature in shoe lining face raises, humidity increases, when humidity increases to a certain degree,
The resistance value of Graphene flexible electronic skin becomes big, and during input current, the magnitude of voltage of humiture collection unit is relatively big,
This magnitude of voltage is input to have arranged in the voltage comparator of threshold voltage, owing to input voltage is more than set
Threshold voltage, exports high level.This high level voltage is input in operational amplifier carry out necessarily voltage
The amplification of ratio, is then added to the resistance wire two ends of shoe pad, and resistance wire heating carrys out drying shoe-pads, when shoe pad quilt
During drying, the humidity of shoe pad reduces, and during input current, the magnitude of voltage of humiture collection unit reduces, this voltage
Value is input to have arranged in the voltage comparator of threshold voltage, owing to input voltage is by less than set threshold value
Voltage, output low level, thus the heating of resistance wire is cut off, shoe pad is returned to normal state.With regard to this
Sample, along with the change of footwear humidity, shoe pad carries out self-heating and from the continuous circulation cut off.
