Description
Technical field
Field more particularly to a kind of simulation of human body electronic skin are designed and produced the present invention relates to a kind of bionic skin
Novel sensory perceptual system structure.
Background technique
With industrialization, intelligence, informationization continuous fusion, robot science and technology be representative industrial information ecology potential
Head is swift and violent, and it is more and more wider that tactilely-perceptible is applied to crawl control, state judgement, pattern-recognition in robot.This requires
It has the sensing capability as the mankind, can instant judgement go out to be crawled to obtain the tactilely-perceptibles such as object property, material characteristics
Aspect required for system.Wherein electronic skin sensory perceptual system is related to the next generation as a kind of important flexible sensory perceptual system
The multifunction of the equipment such as robot, Intelligent hardware, information-based and industrialization.More and more scientists are thus had received to close
Note.This is the emphasis of current academia's research, such as needs to survey to guarantee the optimal seat position of automobile in industry
It measures each position on seat to be distributed the pressure tactile of human body, in order to measure the closed performance of car door, need to door weather strip
Perception is measured in shutdown.In Human biology, rehabilitation training needs the occasion of many contact perceptual signals, example
Such as in sports field, in order to improve the achievement of sportsman, can by vola with the pressure that contacts perceive size and judge
In place whether, to targetedly be corrected, carrying out corresponding analysis using data has for sportsman's power output and movement
Vital effect.Thus softness haptic perception system can be applied to monitoring human health, guarantee safe occasion.
In general, tactilely-perceptible system includes tactilely-perceptible system, pressure sensation sensory perceptual system, power-torque tactilely-perceptible system
System, accelerometer, deformation metering etc., can be generally divided into three classes by function division, and the first kind is flexible skin or artificial skin,
It studies in the world recently more intimately, it is by that can divide mostly that this, which is the property that testee is measured by contacting characterization,
It distinguishes that the array system of millimetre-sized spatiality is constituted, also becomes electronic skin, be mostly applied on wearable artificial skin, cover
Lid medical treatment, robot field；Second class be hard skin touch sensor, mainly include accelerometer, force-sensing sensor, power/
Torque array sensor etc., it is characterised in that one group of touch sensor includes multiple single node tactilely-perceptible systems, and end value is
It is made up of the mean value of multiconductor sensor, thus there is better resolution ratio.The production of Catalonia technology university one
Arm installs the industrial robot of hard skin, in terms of detection contact force, contact position and collision to have achievement more.Harbin
Polytechnical university Cai Hegao academician can detecte three-dimensional force with touch sensor on arc welding robot.Third class is that interior contact passes
Sensor is that this kind of perceptron does not detect the correlative of ambient enviroment, but detects inside hardware system with the above two differences
State, such as industrial robot arm joint/power and torque sensor.But such sensory perceptual system is low in the presence of such as resolution ratio, connects
Touching position is difficult to the limited disadvantage of perception informations such as determining.This is one of today's society Research Challenges and emphasis.
As industrialization and information-based continue universal propulsion, the tactilely-perceptible system equipment of artificial skin class will present huge
Big market-oriented prospect.It will be the following point for putting forth effort development in frivolous property, high integration, excellent electric property.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of the novel of the simulation of human body electronic skin of good seal performance
Sensory perceptual system structure both can be improved with solving the contradiction in distributed sensing system between positioning accuracy and system complexity
Positioning accuracy does not increase the complexity of system again to ensure that the low cost and reliability of system.
In order to solve the above technical problems, the technical scheme is that
A kind of novel sensory perceptual system structure of simulation of human body electronic skin, the structure includes based on acrylamide and lithium chloride
Alignment layers gel and be based on ionic liquid BMIMBF4Polymer sensing layer gel；It is described to be determined based on acrylamide and lithium chloride
Position layer gel and it is described be based on ionic liquid BMIMBF4VHB band is equipped between polymer sensing layer gel.
The alignment layers based on acrylamide and lithium chloride are by single layer ionic gel structure as a preferred technical solution,
At conducting resinl is made by acrylamide and lithium chloride in the single layer ionic gel.
The acrylamide of sensing layer is wherein prepared, Acrylamide is usually colorless and transparent flat crystal, and molecular formula is
C 3H5NO, molecular weight 71.08, sterling are white crystalline solid, and soluble easily in water and methanol is slightly dissolved in chloroform and ethyl acetate,
It is slightly soluble in benzene, hydrolyzable is at acrylic acid in acid or alkali environment.
The LiCl of sensing layer is wherein prepared, Lithium chloride is white cubic crystal or powder.Easily deliquesce.Molecule
Amount 42.39, is highly soluble in water, ethyl alcohol.Lithium ion radius is smaller, and its hydratability is stronger, thus the water-soluble ratio of lithium chloride
Other chlorides are much bigger, and concentration is big, and electric conductivity is better, are suitable as in gel systems.
As a preferred technical solution, the alignment layers based on acrylamide and lithium chloride specific the preparation method comprises the following steps:
It takes the acrylamide monomer of 14wt% to be dissolved in water, the crosslinking agent N of 0.028mol%, N-Asia is separately added into according to molar ratio
Bisacrylamide, i.e. MBAA, the thermal initiator Ammonium Persulfate 98.5 of 0.031mol%, i.e. the catalyst n of APS and 0.152mol%,
N, N ', N ' tetramethylethylenediamine, i.e. TEMED, are dissolved in acrylamide solution, form gel mixed liquor；Take 2mol/L's
Lithium chloride solution 5ml adjusts dosage according to gel equal proportion, is mixed in acrylamide mixed liquor, after mixing evenly, is placed in
Long 50mm, wide 50mm, in the closed container of thick 1mm, wherein four fixed points are for the reserved test of colloid positioning system in colloid
Point, 50 DEG C of standings 3 as a child can plastic.
It is described based on ionic liquid BMIMBF as a preferred technical solution,4Polymer sensing layer is divided into three parts,
Wherein ionic gel layer is located at centre, and active carbon layer covers ionic gel two sides, and current collector aluminum foil covers outermost layer, intermediate ion
Gel bionic human skin, while ionic charge is provided for perception gel, active carbon layer is in physical absorption ionic liquid
Zwitterion, aluminium foil exports charge, while surface resistant to collapsing presses.
The ionic liquid that the ion glue-line is selected as a preferred technical solution, is 1- butyl -3- methylimidazole tetrafluoro
