At forty thousand feet, temperatures can drop below negative sixty-five degrees Fahrenheit.
At the lower elevations below 5000 feet, temperatures are hotter; the mean daily high temperature at Yosemite Valley (elevation 3966 feet) varies from 46-90 °F.
Cattle feet temperatures ranged from 18.7°C to 31.7°C, with the highest value being recorded the day before foot lesions were visible, but at the same time as the first lesion on the tongue.
Unpublished work by the current authors involving five cattle, five sheep and five pigs infected with the Asia 1 strain of FMDV discovered that it was easy to measure the feet temperatures of the animals and established that there was potential for using the technique in the field.
So animals like the arctic fox, whose foot temperature is just a degree or so above freezing, have changes in their hemoglobin genes that enable the protein to release oxygen more easily at very low temperatures.
These results demonstrate the feasibility of using FOs with embedded sensing to monitor plantar surface foot temperatures during normal daily activities and for extended periods and show that periods of increased activity can be identified using foot temperature data.
Foot temperature has long been advocated as a reliable noninvasive measure of cardiac output despite equivocal evidence.
A threshold-based algorithm was developed to identify time periods of high activity from foot temperature data.
In this study, the relationship between the gait condition and foot temperature distributions inside footwear was investigated using subject experiments.
This study aimed to test novel designs for FOs with embedded sensing that were produced via additive manufacturing and determine if foot temperature measurements could be used to detect periods of increased activity.
