Claim 7:
8. A device, comprising:
a wearable band wearable by a subject, the wearable band comprising:
an inward-facing surface that faces towards or rests against the subject as the subject wears the wearable band;
an outward-facing surface opposite the inward-facing surface that faces away from the subject as the subject wears the wearable band; and
a recess on the inward-facing surface extending into the wearable band towards the outward-facing surface;

an elastic coupling member attached to the wearable band in the recess wherein
the elastic coupling member is formed as a spring configured to hold an expanded form, an extended 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; and

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; and
a housing attached to the wearable band; and

a processor attached to the wearable band and electronically coupled to the sensor, wherein the processor is configured to take a measurement from the subject via the sensor.
