what do you mean? i always look exactly like that when i put my arm up
basically yes… there will always be some delta between “core” temp and extremities, even if the chip is placed on the inside of the arm… but one hopes that this delta is constant and linear and easily calibrated for… which is harder and harder to guarantee the smaller and further away the extremity gets.
the problem is the term “core”… even with a thermometer in your mouth, you are not getting “core” temperature… it’s a misnomer that has creeped into the lexicon. To get a “core” temperature, you at least need a rectal thermometer, or at best a thermometer centered in your thorax… somehow… so achieving “core” temp is not a practical goal… what you want to do is look for a place that gives you a stable temperature, then look for big changes.
For example, if you place it in your armpit area and get a reading of 95F pretty consistently, then suddenly get a reading of 99F then you’ve probably got a fever. If you want to get “closer” to what a mouth thermometer might report, then come up with a little calibration routine… so 95F on the xBT shows 98F on the mouth thermometer… then 99F on the xBT would approximate to 101F on the mouth thermometer.
All the tissue folds and range of motion there means it could pinch up in the tissue during normal activities… and there is scar tissue that can form in an uncomfortable configuration because of all those folds and motions… and the hair and bacteria might cause some issue with installation complications… etc. etc. etc.
Someone here put chips (multiple) in their face / head and also I’ve seen a non-DT implant put in the cheekbone area of the face.
There is no standard for these application bits and I don’t think there are any other chips like this that function by putting temp data into the application bits either… probably due to patents.
