Description

Thick yarn and sensitive yarn are integrated in the knitting piece to create an pressure area that can be use as a sensor or on/off switch.

Instruction:

1

Cast on a plain knit and knit a few rows with the carriage settings in basic position A.

2

Pull out every fourth needle into position D, as shown in the diagram.

3

Wrap the wool and pressure-sensitive yarn around the selected needles.

4

Knit one row. Repeat this process 20 times.

5

This was the description of the pressure sensor, but we miss then the electrical connections to make it work - refers to the red sample.

Here comes the description (it is not a bad idea to try first the weaving technique and then do again with these missing steps).

This connection work comes after about 4 or 5 rows with knit-weaving technique. The conductive thread is knitted "by hand", on the needles with the main yarn used for plain knitting. Here we start from the left side (let the carriage in the left and thread off the main thread from the yarn feeder)

6

Pay attention when it is in the pressure part : The resistive yarn must keep its position, and you have to wrap it around the selected needles as previously.

7

Go on, and stop the work with the conductive thread before the end of the "weaving work part" (this thread doesn't need to be on the whole line). Keep going until the last working needle with the main thread.

8

Then on the way back, still by hand, take again the conductive thread and keep going, paying attention on the weaving part. Work with both threads until the last working needle on the left.

9

Then continue with the knit-weaving technique on about 15 rows and do again these connexions steps.

To finish after the last rows with ocnductive thread, knit again the knit-weaving technique on about 5 rows and then plain knit.
