I claim the ornamental design for an earpiece having sensor for measuring physiological data, as shown and described.
FIG. 1 is an outside perspective view of the earpiece having sensor for measuring physiological data;
FIG. 2 is an outside side view of the earpiece having sensor for measuring physiological data;
FIG. 3 is an inside side view of the earpiece having sensor for measuring physiological data;
FIG. 4 is a front view of the earpiece having sensor for measuring physiological data;
FIG. 5 is a rear view of the earpiece having sensor for measuring physiological data;
FIG. 6 is a top view of the earpiece having sensor for measuring physiological data; and,
FIG. 7 is a bottom view of the earpiece having sensor for measuring physiological data.
The broken line showing of a structural feature is included for the purpose of illustrating non-claimed subject matter and forms no part of the claimed design.
