如图4所示，在本发明织物型压力传感器的制造方法的第二优选实施例的流程图中，所述织物型压力传感器的制造方法开始于步骤400，步骤400之后进行到步骤401，将传感织物裁剪成预定的尺寸，并通过缝纫的方法连接柔性导电线与传感织物的导线。随后，到下一步骤402，采用电学性能测量仪测量所述传感织物的导电率和灵敏度。随后，到下一步骤403，采用导线连接工具和缝纫的方法连接所述传感织物和导线。随后，到下一步骤404，采用电阻仪根据传感织物的导电率和灵敏度判断传感织物和导线之间的连接质量。随后，到下一步骤405，通过夹持***在预定的张力下固定所述传感织物。随后，到下一步骤406，通过下转换层定位盒粘合下转换层和所述传感织物。随后，到下一步骤407，通过上转换层定位盒粘合调节柱和传感织物，通过上转换层定位盒粘合上转换层和调节柱。最后该方法结束于步骤408。由于采用本发明的制造方法制造织物型压力传感器，使得可以简单方便的制造织物型压力传感器。制造前测量传感织物的导电率和灵敏度使得传感织物可以更好的与上转换层、下转换层连接，并保证与导线的良好接触。
如图5所示，在本发明织物型压力传感器的制造方法的第三优选实施例的流程图中，所述织物型压力传感器的制造方法开始于步骤500，步骤500之后进行到步骤501，将传感织物裁剪成预定的尺寸，并通过缝纫的方法连接柔性导电线与传感织物的导线。随后，到下一步骤502，采用电学性能测量仪测量所述传感织物的导电率和灵敏度。随后，到下一步骤503，采用导线连接工具和缝纫的方法连接所述传感织物和导线。随后，到下一步骤504，采用电阻仪根据传感织物的导电率和灵敏度判断传感织物和导线之间的连接质量。随后，到下一步骤505，通过夹持***在预定的张力下固定所述传感织物。随后，到下一步骤506，通过下转换层定位盒粘合下转换层和所述传感织物。随后，到下一步骤507，通过上转换层定位盒粘合调节柱和传感织物，通过上转换层定位盒粘合上转换层和调节柱。随后，到下一步骤508，通过定位粘合重量板对粘合区域施加压力，最后该方法结束于步骤509。通过定位粘合重量板施压使得上转换层、传感织物、下转换层之间的连接更加牢固，不会产生错位移动。
如图6所示，在本发明的电学性能测量仪的优选实施例的结构示意图中，所述电学性能测量仪包括电阻仪12、试样台13和测试电极11。测试电极11用于接触所述传感织物两端，电阻仪12用于读取传感织物阻值，试样台13用于固定传感织物并对传感织物两端施加拉力。测试时，将待测的电阻型传感织物试样15平放于试样台上，并在织物两端施加拉力，以达到设定的织物应变，并由试样台上的标尺读出。通过调节织物两端的拉力，可调整施加的织物应变。随后，用两端的夹持器17将织物夹持住。将测试电极11置于传感织物导电层16上进行织物电阻的测试。测试电极11的间距可以调节，可测试不同试样长度的电阻。测量电极11与传感织物导电层16之间的接触压力可通过调整电极上部施加的压力的调节块14加以调节。传感织物的电阻由电阻仪12读出。同时，根据织物试样15的电阻变化率和应变量可计算出传感织物的灵敏度系数。计算公式为：
K=(ΔR/R0)/ε (1)
式中：K是传感织物的灵敏度系数, R0是传感织物的初始电阻, ΔR是传感织物的电阻变化量, ε是对传感织物施加的应变。电学性能测量仪可以对不同长度的传感织物进行电阻和张力应变关系的测量；调节块14的设置可以对传感织物进行不同接触压力下应变和电阻关系的测量，计算出传感织物的灵敏度。
如图7所示，在本发明导线连接工具的优选实施例的结构示意图中，所述导线连接工具包括导线距离控制孔21、固定平台22以及导线指示线23。导线距离控制孔21位于所述导线连接工具中间，用来控制导线之间的距离，固定平台22固定传感织物并用于缝纫连接传感织物和导线，导线指示线23位于固定平台22表面，用于指示导线的位置。导线连接时，首先将传感织物在一定的预张力下平整地放置在固定平台22上，横跨过导线距离控制孔21并将织物两端固定于固定平台22上，这样可使得织物在与导线的缝纫连接过程中不易变形并保持试样的一致性。导线指示线23可帮助织物放置时，织物导电条与导线互相垂直，并确定导线在传感织物上的连接位置。导线指示线23也可提高连接加工过程中两根连接导线的平行度和间距的精度，从而提高连接质量和一致性。采用缝纫的方法实现柔性导电线与传感织物的导线连接。该方法连接可靠，而且不会影响传感织物本身的柔性。
如图8所述，在本发明传感器结构部件组合工具的优选实施例的结构示意图中，所述传感器结构部件组合工具包括夹持***31、下转换定位盒32、上转换定位盒33以及定位粘合重量板34。夹持***31用于在预定的张力下固定所述传感织物，下转换定位盒32用于粘合下转换层和所述传感织物，上转换定位盒33用于粘合调节柱和所述传感织物、粘合上转换层和所述调节柱，定位粘合重量板34用于对所述下转换层、所述传感织物、所述调节柱以及所述上转换层之间的粘合区域施加压力保证它们之间的牢固连接。在压力传感器组合加工时，将传感织物35在规定的预张力下按规定位置固定放置于夹持***31上。并用布夹将传感织物两端夹持住。连接线定位槽37用于传感织物放置于夹持***31固定时传感织物连接导线的定位。同时，将下转移层放于传感器结构部件组合工具下转移层定位盒32中，并在下转移层与传感织物连接粘合的两端涂上适量的粘合剂。然后，将夹持***31和下转移层定位盒32镶嵌组合，使得传感织物35位于下转移层上面，并定位准确。将上转移层定位盒33放置于下转移定位盒32和传感织物35之上，并准确定位。在调节柱和上转移层的粘合区涂上适量粘合剂，按先后放入上转移层定位盒的放入槽孔中。然后，将定位粘合重量板34放置于上转移层定位盒之上，对上、下转移层、传感织物和调节柱各粘合区施加定位压力，使之粘合。上、下转移层定位盒和定位粘合重量板34上定位孔36、38和39用于传感器结构部件组合工具中各部件组合时的准确定位。通过以上工具和加工步骤，完成织物压力传感器的制作。传感器结构部件组合工具使得织物型压力传感器的各层可以很好的连接。
如图8所示，作为本发明传感器结构部件组合工具的优选实施例，定位粘合重量板34包括对选定区域施加压力的凸头341。将定位粘合重量板34放置于上转移层定位盒之上时，通过定位粘合重量板34上的凸头341，对上、下转移层、传感织物和调节柱各粘合区施加定位压力，使之粘合。凸头341的设置可对粘合区准确定位，施加定位压力。
