Footstep analysis using Pressure Sensors

The pressure sensors are represented by black circles, which are located in the three zones of each foot. For the left foot: S1 and S2 cover the forefoot area. S3, S4, and S5 the midfoot area. S6 and S7 the rearfoot or heel area. Similarly, for the right foot: S8 and S9 represent the forefoot area. S10, S11, S12 the midfoot area. S13 and S14 the heel area. The values of each sensor are read by the analog inputs of an Arduino mega 2560.

压力传感器以黑色圆点表示，分布于每只脚的三个区域。对于左脚而言：S1 和 S2 覆盖前足区域；S3、S4 和 S5 覆盖中足区域；S6 和 S7 覆盖后足或跟部区域。同理，对于右脚：S8 和 S9 表示前足区域；S10、S11 和 S12 表示中足区域；S13 和 S14 表示跟部区域。每个传感器的数值通过 Arduino mega 2560 的模拟输入进行读取。
