  • This arrangement has been found to be particularly beneficial because the waveform shape of the tracks 40 allows for the fabric of the leg panel 60, 62 to be stretched during use of the shorts 100 without unduly affecting the electrical resistance provided by the tracks 40. That is, the wavelength and/or amplitude of the waveform can vary to thereby minimise stretching of the one or more conductive layers of the track.

  • Each printed ink circuit 20a, 20b is formed by printing of a series of conductive and non- conductive layers onto the fabric of the shorts (i.e. the fabric of each of the left and right leg panels 60, 62). An appropriate method of printing the printed ink circuits 20a, 20b is described in GB2555592A.

  • This arrangement ensures that the conductive ink layer 122 can provide an electrical connection between the electrodes 22a, 22b, 24a, 24b, 26a, 26b, 28a, 28b and the controller socket 200, via the bridge device 90 and wiring harness 300, while the second non-conductive layer 124 prevents any direct electrical connection between the conductive ink layer 122 and the skin of the user other than in the regions of the electrodes.
  • the first non-conductive ink layer 120 serves not only to electrically isolate the conductive ink layer 122 from the fabric of the leg panels 60, 62, it also minimises stretching of the fabric in the region of each electrode. Minimised stretching is advantageous since this prevents undesirable increases in electrical resistance in the electrodes.
  • Undesirable stretching of the fabric is also achieved by offsetting the perimeter edges of the first 120 and second 124 non-conductive ink layer from the perimeter edge of the conductive ink layer 122. This offset also protects the perimeter edge of the conductive ink layer 122 from damage by peeling or fretting.
  • the second non-conductive ink layer 124 comprises one or more base layers of non-conductive material 125 overlaying the conductive ink layer 122 and at least one encapsulating layer of non-conductive material 126 overlaying the one or more base layers of non-conductive material 125.
  • the at least one encapsulating layer 126 overhangs the one or more base layers 125 so that the at least one encapsulating layer 126 obscures and encapsulates the perimeter edge of the one or more base layers 125.
  • the overhang provides an offset between a perimeter edge of the at least one encapsulating layer 126 and the one or more base layers 125 of about 1mm. This arrangement ensures that load concentrations around the perimeter edges of the second non-conductive ink layer 124 are reduced, and the risk of in-service peeling of the second non-conductive ink layer 124 away from the conductive ink layer 122 is minimised.
