1. A system, comprising:
a wearable hand that is wearable by a subject, the wearable band comprising an inside surface that rests against the subject as the subject wears the wearable band;
a first physiological sensor coupled to the wearable band, wherein the first physiological sensor is:
positioned adjacent to the inside surface of the wearable band;
embedded in the wearable band; or
positioned in the wearable band adjacent to the subject as the subject wears the wearable band;
a second physiological sensor coupled to the wearable band, wherein the second physiological sensor is:
comprised of:
a substrate;
a plurality of intermediate layers composed of at least one of a conductive layer, an insulating layer, and/or a catalyst layer;
parallel rows of microelectrodes composed of nanotube bundles; and
interstitial filler forming a continuous surface around the top surface of at least one of the parallel rows of microelectrodes and with the inside surface of the flexible band; and
embedded in the wearable band;
a pressure sensor coupled to the wearable band, wherein the pressure sensor is:
positioned in the wearable band between the first physiological sensor and the wearable band such that the pressure sensor is positioned to measure a pressure with which the first physiological sensor and/or second physiological sensor is pressed into the wearable band; or
integrated into the wearable band such that the pressure sensor is positioned to measure a strain in the wearable band;
a processor electronically or communicatively coupled to the first physiological sensor, the second physiological sensor and the pressure sensor, wherein the processor is configured to:
receive an electronic signal from the pressure sensor corresponding to the pressure on the first physiological sensor and/or second physiological sensor or the strain in the wearable band;
generate a pressure measurement value representative of the pressure or the strain;
compare the pressure measurement value to a first range of pressure values from a minimum pressure value to a maximum pressure value; and
generate an alert when the pressure measurement value is outside the first range of pressure values; and
a user interface electronically or communicatively coupled to the processor, wherein the user interface is configured to:
receive the alert from the processor;
generate an indicator for the alert; and
present the indicator to the subject.
