Description
Technical field
The utility model relates to a kind of wearable textile structural sensor.
Background technology
In view of current wearable touch sensor receives unprecedented concern, as this class sensor is given robot and the similar people's of artificial limb sensing function.Although follow the development of microelectric technique and the appearance of various organic materials, the research and development proposal of diversified touch sensor has been proposed, at present mostly in laboratory stage, reach the few of industrialization.And existing touch sensor still can not meet wearable application requirements at aspects such as pliability, robustness, sensitivity, particularly can not detect micro-in contact process slide into, cause being difficult to see clearly small stimulation.
Summary of the invention
The purpose of this utility model is to provide a kind of wearable sensor that can see clearly small stimulation and be suitable for volume production.
In order to achieve the above object, the technical solution of the utility model has been to provide a kind of hair follicle Biomimetic Fabric sensor, it is characterized in that: comprise the towel cloth structure by pile stitch and ground organizational composition, pile stitch adopts conductive yam one braiding to form, organize comprise conductive yam two longitudes and latitudes interweave after form x direction of principal axis mixed yarn group and y direction of principal axis mixed yarn group, the structure of conductive yam one and conductive yam two is positioned at the conductive fiber at center and is wrapped in the elastic filament outside conductive fiber identical comprising, by adhesive plaster, the conductive fiber of x direction of principal axis mixed yarn group and y direction of principal axis mixed yarn group is connected to a road current measurement circuit after polymerization respectively separately with conductive yam one.
Preferably, described towel cloth structure is positioned on base fabric.
Preferably, described current measurement circuit at least comprises the power supply and the reometer that are connected in series with described x direction of principal axis mixed yarn group or described y direction of principal axis mixed yarn group.
People's physical efficiency is felt the spread effect such as gentle breeze or filoplume of whipping skin surface, and this depends on and is positioned at the thigmoreceptor that skin surface chaeta root is called hair follicle.In the time that external stimulus acts on chaeta surface, the bending of chaeta taking skin surface as fulcrum prizes the hair follicle tactile feel acceptor that encourages root.This stimuli responsive sensor mechanism is similar to " sense of touch contact convex lens effect ".Amplified the slight curves of skin surface chaeta is out of shape because of lever principle.This mechanical lever structure can be converted to exterior mechanical the dynamic range that is applicable to human perception.
In essence, the flexural deformation of chaeta can be regarded the equivalent mechanical resistance that has changed hair follicle sensing arrangement as.Therefore the variation that, the variation of this equivalent mechanical resistance can any impedance replaces.Given this, no matter in the structure of sensing system, or sensing principle aspect, all can realize based on textile technology.In structure aspects, the filoplume on surface when citation form, this can adopt towel cloth structure, and Mao Jingyu weft yarn interweaves and forms the hair of the bionical human body surface of pile stitch, and ground is organized through interweaving with forming with weft yarn, the skin of bionical human body; Aspect sensing principle, the variation of impedance can resistance variation realize, a loop yarn that is terry pile structure structure is conductive yam, in order to improve resistance variations susceptibility, conductive yam can be used the blending covering yarn of conductive fiber and elastic filament, change and be placed in resistance under organizing by playing the swing of loop yarn, thus have influence on electric current with detect micro-slide into.Like this, the resistance variations of looped structure has been reacted and has been acted on surperficial stimulus intensity.
Compared with existing pneumatic sensor, as the PVDF sonac (patent No. CN103575347A) detecting for air-flow, the utility model has the advantage of make up the sensor micro-slide on be difficult to detect deficiency, and this sensor and weaving combination, can be used for the detection of clothing and sensing, the manufacture of robot bionic fur.In addition, current most of sensors with auxiliary electrode were uses surperficial pressurized deformation to produce the mode of electric signal, and sensors with auxiliary electrode were is equivalent to the effect of skin, and the utility model can serve as the effect of hair, record micro-slide into and air-flow change, be applicable to sensitiveer and wearable demand.

Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
Agent structure of the present utility model is terry pile structure structure, terry pile structure structure is positioned on base fabric 5, terry pile structure structure and hair follicle structure have high similarity, comprise and be projected on surperficial pile stitch part, to be used for measuring micro-slide into etc., also comprise ground tissue part, for be responsible for circuit together with.Conductive fiber 3 as shown in Figure 2 interweaves with the blending covering yarn longitude and latitude of elastic filament 4, and the composition axial mixed yarn group of x and the axial mixed yarn group of y, as ground tissue.
Aspect material, pile stitch will be used conductive yam 1, and conductive yam 1 adopts the blending covering yarn of conductive fiber 3 and elastic filament 4, as shown in Figure 2, play when can swinging change perceived, it is swung and change the variation that can affect the part resistance in ground tissue.In ground tissue part, also adopt conductive yam 1 as shown in Figure 2, play the effect of transmission of electric signals.
When assembling, conductive fiber 3 and the blending covering yarn of elastic filament 4 are made into terry pile structure, and respectively axial x mixed yarn group and the axial conductive fiber 3 of y are used respectively to adhesive plaster 3 polymerizations with conductive yam 1, and access in two current measurement circuits, as described in Figure 3, the simple structure of this current measurement circuit comprises power supply and the reometer of series connection.
Induction process and the method for utility model are as follows:
For the arbitrary utmost point in two circuit, after circuit is connected, if there is a power or micro-sliding as stimulating the conductive yam 1 in pile stitch part, to there is corresponding deformation in conductive yam 1, wherein will there is deformation in the conductive fiber 3 of conductive yam one 1 inside, its length and cross-sectional area will change, and known according to resistance formula, the resistance of conductive fiber 3 will change.Now will produce accordingly a change value by the electric current in circuit, by observe reometer variation can by power or micro-slide for sense.For power size or micro-slide into ionization meter will be by after the utility model test of many times, can obtain the big or small or intensity corresponding relation about curent change value, in the time of practical application, can be according to corresponding relation, record size or intensity by curent change value, more preferably, reometer can be improved, its current value is revised as to corresponding size or intensity, is convenient to direct reading.For external stimulus action direction problem, the utility model adopt two circuit detect respectively in x axle, the axial power of y or micro-slide into, learn the numerical value of two reometers and be converted to i.e. two the component sizes of size of power according to corresponding relation, according to resolution of force, can try to achieve size and the direction of making a concerted effort.
