Claim 11:
12. A system, comprising:
a wearable band wearable by a subject, the wearable band comprising an inward-facing surface and an outward-facing surface;
a housing movably attached to the wearable band, the housing comprising a topside and an underside;
a recess, wherein the recess is formed:
in the wearable band on the inward-facing surface of the wearable band;

an elastic coupling member mounted in the recess wherein;
the elastic coupling member is formed as a spring configured to hold an equilibrium form, an expanded form, and a compressed form;
a sensor coupled to a first end of the elastic coupling member, wherein, as the subject wears the wearable band, the elastic coupling member assumes the compressed form or the expanded form to press the sensor against the subject and causes constant contact between the sensor and the subject;
a flexible hermetic or watertight seal, wherein:
the seal is attached to the inward-facing surface of the wearable band and the sensor to bridge a gap that lies between the inward-facing surface of the wearable band and an inward-facing detection surface of the sensor; the seal and the sensor cover the recess; and the seal seals off the recess from an ambient environment of the wearable band;
the housing, coupled to a second end of the elastic coupling member, attached to the wearable band;
the sensor generates an electronic signal corresponding to a physiological state of the subject; and
the elastic coupling member presses the sensor against the subject and causes constant contact between the sensor and the subject as the subject wears the wearable band.
