The sensor tape can taper from a wide end to a narrow end. The sensor tape can transition from a wide portion to a narrow portion in a step-like change or slope. The sensor tape can have staggered portions. The various tapes can be used with an L-shaped sensor. The various tapes can increase contact surface between the surface of the medium and an adhesive side of the tape so as to reduce motion-induced noise. ## Claims ### Claim 1 A sensor tape for positioning and securing a noninvasive sensor to a skin of a patient to noninvasively measure physiological parameters of the patient, the sensor tape comprising: a first portion at a first end comprising a first width, the first portion configured to position an emitter and a detector of the noninvasive sensor; a second portion at a second end comprising a second width, the second width being greater than the first width; a transition portion between the first portion and the second portion, the transition portion comprising: a first edge extending between the first and second ends along the first and second portions, wherein the first edge is substantially linear between the first and second ends; a second edge extending between the first and second ends along the first and second portions, wherein the second edge transitions between the first end and the second end non-linearly such that the transition portion changes from the first width to the second width along the second edge; and an adhesive surface and a non-adhesive surface on each of the first and second portions. ### Claim 2 (depends on 1) The sensor tape of claim 1, wherein the transition portion comprises a sloped transition along the second edge between the first portion and the second portion. ### Claim 3 (depends on 1) The sensor tape of claim 1, wherein the first and second portions have substantially the same length. ### Claim 4 (depends on 1) The sensor tape of claim 1, wherein the second portion is configured to cover an entirety of the first portion when the sensor tape is secured to the skin of the patient. ### Claim 5 (depends on 1) The sensor tape of claim 1, wherein at least a section of the adhesive surface of the second portion at the second end is configured to secure to the skin of the patient. ### Claim 6 (depends on 1) The sensor tape of claim 1, wherein the first portion is configured to removably secure to the emitter and the detector. ### Claim 7 (depends on 1) The sensor tape of claim 1, wherein the first portion comprises a first magnet, wherein the second portion comprises a second magnet, and wherein the first and second magnets are configured to attract to secure the first portion to the second portion when the noninvasive sensor is secured to the skin of the patient. ### Claim 8 (depends on 1) The sensor tape of claim 1, wherein the non-adhesive surface of the first portion comprises a first alignment indicator aligned with the emitter and a second alignment indicator aligned with the detector. ### Claim 9 (depends on 1) The sensor tape of claim 1, wherein the second edge of the transition portion is closer to the first end. ### Claim 10 (depends on 1) The sensor tape of claim 1, wherein the second edge of the transition portion is closer to the second end. ### Claim 11 (depends on 1) The sensor tape of claim 1, wherein the second edge comprises a linear slope. ### Claim 12 (depends on 1) The sensor tape of claim 1, wherein the second edge comprises a curved slope. ### Claim 13 A sensor tape for positioning and securing a noninvasive sensor to a skin of a patient to noninvasively measure physiological parameters of the patient, the sensor tape comprising: a first portion at a first end comprising a first width, the first portion configured to position an emitter and a detector of the noninvasive sensor; a second portion at a second end comprising a second width, the second width being greater than the first width; a first edge extending between the first and second ends along the first and second portions, wherein the first edge is substantially linear; a second edge extending between the first and second portions, wherein the second edge is non-parallel with the first edge; wherein a width of the tape between the first and second edges decreases from the second end to the first end; and an adhesive surface and a non-adhesive surface on each of the first and second portions. ### Claim 14 (depends on 13) The sensor tape of claim 13, wherein the second edge is substantially linear. ### Claim 15 (depends on 13) The sensor tape of claim 13, wherein the width of the tape between the first and second edges continually decreases from the second end to the first end along an entire length of the sensor tape. ### Claim 16 (depends on 13) The sensor tape of claim 13, wherein the first and second portions have substantially the same length. ### Claim 17 (depends on 13) The sensor tape of claim 13, wherein the second portion is configured to cover an entirety of the first portion when the sensor tape is secured to the skin of the patient. ### Claim 18 (depends on 13) The sensor tape of claim 13, wherein at least a section of the adhesive surface of the second portion at the second end is configured to secure to the skin of the patient. ### Claim 19 (depends on 13) The sensor tape of claim 13, wherein the second portion extends from the first portion to the second end along a longitudinal axis of the sensor tape.
