压力传感器阵列在步态分析和机器人技术中有着广泛的应用。为了满足不同尺寸的需求，降低制造成本，提出了一种可定制的压力传感器阵列的设计方法。可定制的压力传感器阵列由压阻织物和柔性电路制成，这使得它适合于传感器阵列被裁剪成不同的尺寸。压力传感器均匀分布，以保持压力传感器阵列的分辨率时，修剪成不同的尺寸。柔性电路上的导线被设计成确保在将传感器阵列修整成更小尺寸之后，可以使用保留在传感器阵列上的全部/部分传感器。为了评估设计方法，我们设计了鞋垫形状的可定制的压力传感器阵列，以分析步态参数，如步态周期和节奏。分析了传感器阵列在空间和时间上的压力分布规律。实验结果表明，采用本文方法设计的可定制压力传感器阵列能够在不受修调影响的情况下获得空间和时间上的压力分布模式。
Pressure senor array is widely used in gait analysis and robotics. To meet the demand on different sizes and reduce the manufacture costs, in this paper, we proposed a design method for customizable pressure sensor array which could be trimmed into different sizes. The customizable pressure sensor array was made of piezo-resistive fabric and flexible circuits, which made it suitable for the sensor array to be trimmed into different sizes. Pressure sensors were uniformly distributed to maintain the resolution of the pressure sensor array when trimmed into different sizes. Wires on the flexible circuits were designed to ensure that all the full/partial sensors remained on the sensor array could be used after trimming the sensor array into a smaller size. To evaluate the design method, we designed insole shaped customizable pressure sensor arrays to analyze gait parameters such as gait cycle and cadence. Spatial and temporal pressure distribution patterns acquired with trimmed and nont center dot immed sensor arrays were used for analyzing. Experiment results indicated that the customizable pressure sensor array designed with the method proposed in this paper could he used to acquire spatial and temporal pressure distribution patterns without being influenced by trimming.
