The specific embodiment
Article of footwear with the form of sport footwear 10 has been shown in Fig. 1, and it comprises upper of a shoe 12 and footwear sole construction 14.Upper of a shoe 12 is fixed on footwear sole construction 14, and has defined the chamber that holds pin.Footwear sole construction 14 comprises outer bottom 14.1, the middle end 14.2 and the interior end 14.3, and it has formed the bottom of the chamber that holds pin of sport footwear 10.
In illustrative embodiment, the middle end 14.2 that is preferably formed by the shock attenuating material, have the membranous type pressure sensor 16 that is attached to its upper surface.Therefore, during in suitable position, pressure sensor 10 was clipped at the interior end 14.3 and the middle end 14.2 when interior bottom.
As fully illustrating in Fig. 2, pressure sensor 16 comprises a plurality of pressure-sensings unit 18 of the zones of different that is positioned at footwear sole construction 14, and it is used for measuring pin of wearer to 14 applied pressures of footwear sole construction.
The configuration of pressure-sensing unit 18 is described referring now to Fig. 3 and 4.Fig. 3 shows the profile of the element of pressure-sensing unit 18.Pressure sensor 16 comprises the sandwich construction that contains the first carrier film 20, Second support film 22 and interval body 24.Interval body 24 is generally double faced adhesive tape, utilizes interval body 24 that the first and second carrier film 20,22 are laminated to together.The first and second carrier film 20,22 preferably are made of PET, but can be also other materials such as PEN, PI, PEEK.Each carrier film all can be made of single rete, perhaps can comprise a plurality of retes of identical or different material.Interval body 24 preferably includes the retes such as PET, PEN, PI, PEEK, and all is applied with adhesive coatings on every one side of described rete.In each pressure-sensing unit 18, described interval body comprises rectangle or ellipse (oblong) opening 26, the first and second carrier film 20,22 can be forced together in described opening.In each pressure-sensing unit 18, the first resistive electrode 28 permanently is arranged on the first carrier film 20, and the second resistive electrode 30 permanently is arranged on Second support film 22 with the relation of facing with the first electrode 28.Each electrode 28,30 contacts with the corresponding strip conductor 34,36 that extends along the long limit of opening 26.At least one in electrode 28,30 (in this example: electrode 28) be coated with partly for example dielectric layer of electric insulation layer 32().
In response to the pressure that acts on the pressure-sensing unit, at least one in the first and second carrier film 20,22 be towards another carrier film deflection, until carrier film 20,22 or their respective surfaces on element come in contact.In case set up contact, the radius on Mechanical Contact surface will increase along with the increase of pressure.When setting up between electrode 28 and 30 when directly contacting, the resistance between conductor 34 and 36 will become limited, thereby electric current is flow through.Along with the contact area between described first and second electrode 28,30 increases, but the measuring resistance between conductor 34 and 36 reduces. Resistive electrode 28,30 with corresponding strip conductor 34,36 between the position that contacts, the specific electrical resistance of resistive electrode and the shape of electric insulation layer 32 determined pressure-dependent cell resistance.
Because electric insulation layer 32 has prevented the direct contact between first and second electrode 28,30 partly, in there is no those zones of electric insulation layer 32 direct contact might not occur, so can be by the shape of the insulating barrier 32 that suitably is shaped, regulate in a predetermined manner the electroresponse function of pressure-sensing unit, that is, resistance is to pressure.There is no need to regulate other parameter of pressure-sensitive unit, for example the material of electrode.Fig. 5 schematically shows the difference in the electroresponse of the pressure-sensing unit (full curve 40) that there is no the pressure-sensing of insulating barrier unit (dashed curve 38) and have the insulating barrier that is configured as the shape in Fig. 3, and all other cell parameters are all the same.It should be noted that resistance variations occurs in from activation pressure P for the pressure-sensing unit that there is no insulating barrier
actIn the pressure limit of the less of (pressure when electrode begins to contact) beginning.At P
actAbove, resistance reaches balance at the lower value place rapidly.For the unit that is equipped with insulating barrier, resistance variations stretches in quite long pressure range scope.Therefore, pressure measxurement has been realized in the unit that has insulating barrier under than the much higher pressure in the unit that there is no insulating barrier.
The shape of electric insulation layer 32 is invariable or repetition along main outrigger shaft A, and the electroresponse of unit 18 is basically irrelevant with the accurate location of application point on axle A of compression stress.In illustrative embodiment, electric insulation layer 32 comprises the sequence that is substantially rake tooth part 42 of arranging according to the mode of tooth bar, and described tooth bar is parallel to main outrigger shaft A and arranges.As fully illustrated in institute in Fig. 2, pressure-sensing unit 18 is arranged in the zone of footwear 10, and when the wearer stood, walks or runs, pressure peak can appear in expection in described zone.Particularly, first in the pressure-sensing unit is placed in the zone of head of ossa suffraginis (big toe), in the zone of second head that is placed on first metatarsal bone, the 3rd in the zone of the head of fifth metatarsal bone, the 4th in the zone of calcaneum (heel bone).The main outrigger shaft of each unit 18 corresponds essentially to the upright projection of main outrigger shaft on footwear sole construction of the bone relevant to described unit.This makes the pressure-sensing in described unit reduce the dependence of the size of wearer's pin.In fact, the layout of described pressure-sensing unit has the tolerance limit that reaches to a certain degree, described tolerance limit and pressure sensor design for nominal footwear size relevant with the difference between the actual size of wearer's pin.This size tolerance limit makes and a kind of pressure sensor of size can be used for the footwear size (for example, the continuous footwear size of three in the system of Continental Europe) of certain limit.
Be the middle end in this example of footwear sole construction 14(for pressure sensor 16 is fixed to), pressure sensor 16 comprises that one or more anchor pad 44(are referring to Fig. 2).But anchor pad 44 preferably includes pressure-sensitive adhesive layer or hot activation adhesive layer; described adhesive layer is subject to the protection of release liner (release liner) at first, removes described release lining before the support element that pressure sensor 16 is attached to its footwear sole construction 14.
Balanced for the air pressure in the opening 26 that makes interval body 24, each pressure-sensing unit 18 includes passage 58(and provided abundant diagram in Fig. 2 and Fig. 3).Passage 58 is extremely outside with the internal fluid communication of pressure-sensing unit, thereby has basically avoided the compression of the gas of inside, pressure-sensing unit, therefore can be to the response curve obvious of each unit 18.Additional or alternatively, passage 58 can be communicated to the pneumatic reservoir in the membranous type pressure sensor.
