This paper presents a critical evaluation of the inductor
characteristics of circular weft knitted coils for applications in etextiles. Inductors are knitted using circular needles with thin
insulated metal wire and yarn knitted together. The resulting
helical coils are characterized as a function of number of turns,
coil diameter, needle size and insulated metal wire material. The
results are compared to wound coils. Simulations of the knitted
and wound coils show close agreement with the experimental
results and confirm a higher inductance for the knits compared
to the wound coils with the same pitch between turns. The
parasitic coil capacitance is higher in the knit due to the vertical
legs of the stitches, absent in wound coils. Knits with thin Cu and
Litz wires result in flexible and wearable textile coils.
