In the present embodiment, the first base fabric 6 and the second base fabric 1 are pure polyester plain weave fabrics, and the grammage of the fabrics is 130g/m 2 The warp density and weft density are 300 roots/10 cm. The first conductive yarns 5 and the second conductive yarns 2 are silver-plated conductive nylon filament yarns, the linear density is 77.78dtex/2, and the resistance per unit length is 8.6 ohm/cm. The first flexible pressure-sensitive sensing points 4 and the second flexible pressure-sensitive sensing points 3 are made of conductive composite materials, and comprise a polymer matrix and conductive fillers. The polymer matrix is wet polyurethane resin, the molecular weight of polyurethane is 29000-31000, and the 100% modulus is 50-60kg/cm 2 . The conductive filler is carbon black, which has a diameter of about 30nm.
In this embodiment, a plurality of first conductive yarns 5 are located on the top surface of the first base fabric 6, and a plurality of second conductive yarns 2 are located on the bottom surface of the second base fabric 1. A total of 8 first conductive yarns 5 are arranged at equal intervals along the warp direction of the first base fabric 6 at a distance of 10 mm; a total of 8 second conductive yarns 2 are arranged at equal intervals along the weft direction of the second base fabric 1 at a distance of 10mm. The plurality of first flexible pressure-sensitive sensing points 4 are positioned above the first conductive yarns 5 and the top surface of the first base fabric 6 nearby, the plurality of second flexible pressure-sensitive sensing points 3 are positioned below the first conductive yarns 2 and the bottom surface of the first base fabric 1 nearby, and the center interval distance of each flexible pressure-sensitive sensing point is 10mm. Fig. 2 shows a side view of the fabric pressure distribution sensing array 8 in this embodiment, where the first base fabric 6 is under, the second base fabric 1 is over, and the bottom surface of the second base fabric 1 is opposite to the top surface of the first base fabric 6, so that the directions of the first conductive yarn 5 and the second conductive yarn 2 are perpendicular, the first flexible pressure-sensitive sensing points 4 and the second flexible pressure-sensitive sensing points 3 are located at the intersections of the first conductive yarn 5 and the second conductive yarn 2, and the plurality of first flexible pressure-sensitive sensing points 4 and the plurality of second flexible pressure-sensitive sensing points 3 are in one-to-one correspondence and form the sensing unit 7, as shown in fig. 3. The sensing unit 7 separates the first conductive yarn 5 from the second conductive yarn 2, and when external pressure acts, the first flexible pressure-sensitive sensing point 4 is contacted with the second flexible pressure-sensitive sensing point 3, so that the first conductive yarn 5, the sensing unit 7 and the second conductive yarn 2 realize the conduction of a circuit.
The preparation method of the fabric pressure distribution sensing array with the double-layer laminated structure comprises the following steps:
step 1: adding carbon black with the particle size of 30nm into N, N-dimethylformamide to prepare a mixed solution with the carbon black mass fraction of 13.33wt%, and placing the mixed solution into an ultrasonic dispersing instrument for preliminary dispersion for 10min;
step 2: and adding the polyurethane resin solution into the mixed solution after the dispersion to form a carbon black/polyurethane mixed solution with the carbon black mass fraction of 5.4wt%, manually stirring for 2min by using a stirring rod, and then placing into an ultrasonic dispersion instrument for uniform dispersion for 180min to obtain the conductive composite material solution for manufacturing the flexible pressure-sensitive sensing point.
Step 3: sewing the first conductive yarns 5 on the top surface of the first base fabric 6 at intervals of 10mm in the warp direction of the first base fabric 6 using a sewing machine, and sewing 8 conductive yarns in total; the second conductive yarn 2 was sewn to the bottom surface of the second base fabric 1 at intervals of 10mm in the weft direction of the second base fabric 1, and 8 conductive yarns were sewn in total.
Step 4: the method comprises the steps of adopting a screen printing method, using a screen printing plate with the specification of 8 multiplied by 8 of a circular hole array, the diameter of a circular hole being 3mm and the center distance of the circular hole being 10mm, using a full-automatic plane screen printer to print the prepared conductive composite material solution onto the top surface of a first conductive yarn 5 and the nearby first base fabric 6 and the bottom surface of a second conductive yarn 2 and the nearby second base fabric 1, preparing a first flexible pressure-sensitive sensing point 4 and a second flexible pressure-sensitive sensing point 3, and enabling the conductive composite material solution to completely cover the first conductive yarn 5 and the second conductive yarn 2. After the conductive composite material solution is completely dried at normal temperature, a plurality of first flexible pressure-sensitive sensing points 4 and a plurality of second flexible pressure-sensitive sensing points 3 are formed.
Step 5: the second base fabric 1 and the first base fabric 6 are overlapped in such a manner that the bottom surface of the second base fabric 1 is opposite to the top surface of the first base fabric 6 and the first conductive yarns 5 are perpendicular to the second conductive yarns 2, so that the first flexible pressure-sensitive sensing points 4 printed on the first base fabric 6 and the flexible pressure-sensitive sensing points 3 printed on the second base fabric 1 are in one-to-one correspondence, thereby forming the sensing unit 7. When subjected to pressure, the first conductive yarn 5 sewn to the first base fabric 6, the sensing unit 7 and the second conductive yarn 2 sewn to the second base fabric 1 provide for the conduction of an electrical circuit.
One sensing unit 7 of the fabric pressure distribution sensing array 8 of example 1 was randomly selected and its corresponding first conductive yarn 5 and second conductive yarn 2 were connected to a digital bridge, respectively. Pressure is applied in a direction perpendicular to the surface of the sensing unit 7, and then unloaded, and the response law of the resistance of the sensing unit 7 with the change of pressure is recorded. Under the condition of no pressure, the contact degree of the first flexible pressure-sensitive sensing point 4 and the second flexible pressure-sensitive sensing point 3 is weak, and the initial resistance value of the sensing unit 7 is large (> 20MΩ) and is close to the open circuit state. When a slight pressure is applied, the initial resistance of the sensor unit 7 is measured to be about 16kΩ. Fig. 4 shows the resistance change of the measured sensor unit 7 in the load-unload pressure range of 0-60 kPa. As can be seen from the figure, as the pressure increases, the contact degree of the two corresponding flexible pressure-sensitive sensing points increases, and the two flexible pressure-sensitive sensing points are pressed and thinned, so that the conductive paths formed by the conductive fillers in the polymer matrix increase, the conductive capacity of the sensing unit 7 is obviously enhanced, and the resistance value is obviously reduced; then the pressure gradually decreases, the contact degree of the two corresponding flexible pressure-sensitive sensing points is weakened, the initial state is restored, the electric conduction capacity of the sensing unit 7 is weakened, and the resistance value is restored to the initial value. During the pressure and pressure relief process, the resistance value of the sensing unit 7 is obviously changed, and the signal output keeps high consistency.
Applying periodic alternating pressure to the sensing unit 7, recording the response rule of the resistance of the sensing unit 7 along with the pressure, and showing a relation chart of the resistance value of the sensing unit 7 to be measured along with the change of the external periodic pressure (0 kPa-60kPa-0 kPa) in FIG. 5. As can be seen from the figure, in the 500-cycle test, the sensing unit 7 can continuously and stably output the resistance change signal, and the peak value and the valley value of the output resistance signal can be kept stable in the whole test process, so that the sensor has good working stability.
Fig. 6 shows a fabric pressure distribution acquisition system formed by connecting a fabric pressure distribution sensing array 8 and a peripheral signal acquisition circuit in the present embodiment, where a microcontroller controls a column selector to output a reference voltage to a certain column, controls a row selector to acquire a voltage signal of a certain row, converts the voltage signal into a digital signal through an analog-to-digital converter, and sends the digital signal to a computer or a mobile phone. Fig. 7 shows a pressure distribution cloud image drawn with data collected by the fabric pressure distribution collection system in this embodiment.
The result shows that the fabric pressure distribution sensing array with the double-layer laminated structure is prepared by oppositely laminating two layers of fabrics, the thickness of the sensing array is thinner, the flexible pressure-sensitive sensing points are firmly connected with the conductive yarns, and the crosstalk effect between sensing units in the sensing array due to serial-parallel connection channels is effectively reduced.
