Abstract: A strap band including a flexible wire bus having electrodes and wires coupled with the electrodes is described. The wire bus may be include in a strap band formed by molding an inner strap, mounting the wire bus in the inner strap, and injection molding an outer strap over the inner strap and wire bus to form a strap band. The electrodes may be positioned on the inner strap to accommodate a target range of a body portion the strap band may be worn on. A material of the strap band and a material the wire bus may be selected to allow a low coefficient of friction between the wire bus and strap band so that loads applied to the strap band may not be coupled with the wire bus or cause damage to wires due to pull and/or torsional load forces applied to the strap band.
