1. A device configured to be secured to a person, said device responsive to one or more measurements on a skin surface of the person, the device comprising:
a body comprising a first side configured to be in contact with the person, said first side including a first sub-portion configured to contact a first skin surface on a dorsal side of a wrist of the person, said first sub-portion comprising an outer perimeter;
a strap configured to secure the body to the wrist of the person;
a cutout in the first sub-portion, wherein said cutout comprises a shape including an inner perimeter and wherein said cutout is enclosed entirely within the outer perimeter;
a thermal stimulus source in thermal communication with the first skin surface, wherein the thermal stimulus source comprises a surface area extending on a portion formed on the first sub-portion between the inner perimeter and the outer perimeter;
an environmental temperature sensor configured to measure ambient temperature, said environmental temperature sensor positioned on a second side of the body opposite the first side including the thermal stimulus source;
a skin temperature sensor configured to measure a temperature of the first skin surface, wherein the skin temperature sensor is positioned within the cutout;
a hardware processor configured to couple with the environmental temperature sensor and the skin temperature sensor; and
an interstitial gap within the body between the first side and the second side, wherein the interstitial gap is configured to separate the hardware processor and the environmental temperature sensor from the thermal stimulus source.
