Rules for sensor integrated substrates

A wound dressing comprising:

• a substantially flexible substrate including a plurality of openings configured to allow fluid to pass through the substantially flexible substrate, the plurality of openings constraining widths of a plurality of regions located between adjacent openings;
• a plurality of electronic components positioned on the substantially flexible substrate, the plurality of electronic components comprising a first electronic component configured to output digital data and a second electronic component configured to output analog data;
• and
• a plurality of conductive tracks positioned on the substantially flexible substrate, the plurality of conductive tracks comprising:
• a first conductive track positioned in a first region of the substantially flexible substrate, the first conductive track being connected to the first electronic component, the first conductive track having a first minimum width selected to maintain integrity of a first digital electrical signal conducted by the first conductive track, the first minimum width being constrained by a width of the first region;
• and
• a second conductive track positioned in a second region of the substantially flexible substrate, the second conductive track being connected to the second electronic component, the second conductive track having a second minimum width selected to maintain integrity of a second analog electrical signal conducted by the second conductive track, the second minimum width being constrained by a width of the second region, and the second minimum width being larger than the first minimum width of the second conductive track.
