of the first peak and positive component of the second peak, leading to a reduction in amplitude for the second peak, as shown in Figures 35(b-i). I n Table S5, the last two columns of the table indicate the comparison results of the current peak with the former peak (i.e., the second peak with the first peak, and the third peak with the second peak). The comparison results are roughly categorized into three classes, i.e., larger ("L"), equivalent ("E") and smaller ("S"). With the overlapping effect, the large/small (former electrode is large and current electrode is small) the comparison result is always "S", same as the electrode pattern. Similarly, results of large/large and small/small can be "E" or "S", while results of small/large comparison can be "L" or "E". For the patterns with only two strip electrodes (direction 1 and 8), only one comparison is required for forward and backward sliding. Based on the comparison results as indicated in the table, they can be easily differentiated. For the other six directions with three strip electrodes, whenever an "L" comparison result appears in the forward and backward sliding, it means that the current electrode must have a larger electrode width than the former one. That is, the current electrode width is large, and the former electrode width is small. If both the forward sliding and backward sliding have "L", the electrode pattern can be easily interpreted, such as direction 3 and 6. Then the other directions can be interpreted according to the comparison results in Table SI. Table S5. Signal interpretation table (comparison result of the current peak amplitude with the former one: "L" - larger, "E" -equivalent, "S" - smaller).
