Figure 2: Knitted pressure sensors tested with different pressures. Pressure was changed by either changing the area of applied force (black) or the applied force (red). (a) Data collected using the knitted pocket pressure sensor. The sensor was sensitive to changes in the applied force ([INSIDE:1]) and changes in the area over which force was applied ([INSIDE:2]); however, in both cases, the responses were different making extracting meaningful pressure data problematic. (b) Pressure against the change in capacitance collected using the knitted spacer pressure sensor. Below 25 kPa, the sensor gave a similar response regardless of whether pressure was changed by altering the force ([INSIDE:3]) or the area that the force was applied to ([INSIDE:4]). The relationship was similar regardless of whether force or area of applied force was changed
