Figure 4

Two parallel fabrication steps are involved for the realization of the smart bandage system. Bottom electrode fabrication using carbon ink on paper and wireless electronics fabrication using double-sided inkjet printed circuit board on kapton. (a) Carbon ink spreading on paper. (b) Cutting of bottom electrode using laser. (c) Separated bottom sensor electrode. (d) Processing of bottom side of the kapton tape. (e) Inkjet printing bottom side of the circuit board. (f) Inkjet printing top side of the circuit board. (g) Mounting of circuit components using silver epoxy. (h) The bottom electrode and the integrated electronics are mounted on the disposable bandage strip. (i) Bottom view of the smart bandage. (j) Top view of the smart bandage. (k) Finally another disposable bandage strip is put on top of the detachable electronics for packaging purpose.
