Fabrication process for the MWCNT/cotton load cells. (a) Raw cotton material after blending process. (b) The cotton aggregate is dipped in MWCNT ink. (c) Dried MWCNT/cotton composite sample. (d) The composite is set in a plastic housing to form a load cell. (e) Prepared load cell with copper wires. (f) These three cells are set in a soft plastic shoe sole with thin plastic tape used to fix them. (g) The insole based-load cells are placed inside a running shoe.
