1. A continuous analyte measurement system, comprising:

  • a base unit configured for mounting on a skin surface;

    an analyte sensor comprising a first side edge and a second side edge defining a width of the analyte sensor, and a proximal portion and a distal portion defining a length of the analyte sensor, the analyte sensor further comprising a first and a second functional sides on opposing surfaces of the analyte sensor, a first conductive layer disposed on the first functional side at the distal portion of the analyte sensor and disposed from the first side edge to the second side edge, and a sensing layer disposed on the first conductive layer in a continuous band orthogonal to the first side edge and the second side edge to define an analyte sensor active area, the active area having a rectilinear polygon shape defined by the intersection of the first conductive layer and the sensing layer disposed on the first conductive layer, the proximal portion configured for positioning within the base unit and the distal portion configured for insertion through the skin surface;

    wherein the base unit comprises a two-piece conductive member including a first piece and a second piece; and

    wherein the base unit comprises a side wall including a slit through which the width of the proximal portion of the analyte sensor is positioned so that the first and second pieces of the conductive member are electrically coupled with the corresponding first and the second functional sides of the proximal portion of the analyte sensor, the base unit further including one or more features on at least one orthogonally adjacent wall to the side wall for exerting a compressive force on each of the first piece and the second piece of the two-piece conductive member, the one or more features aligned with the two-piece conductive member and comprising one or more exterior flexures of the at least one orthogonally adjacent wall to the side wall.
