Not cheap.  The pills seem not to be re-usable and cost £43 pounds each, retail, for 24-36 hours use. Plus about £2,000 for the receiver/data logger.

Edit:   Actually this is remarkably cheap compared with what it would cost to develop and pilot a system to do this.  But still.

It's a sensor is going to be attached to a person while running or performing labor intensive tasks. So what you're saying is that it's kind of impossible to find the "best" kind of sensor? What would be the "best," relatively speaking? IR? IC's dedicated to temp sensing?

What do you want to use the data for?
Monitoring of the testperson's temperature during the task so that he may rest at an appropriate time?
Or adding it to other data after the task for some research purpose?

For the latter the temperature logging pill would do.

How feasable is it to transmit a signal (radio or sound) out of the body from the intestinal tract?
If you could add a transmitter in the temperaturesensing pill then it can send the temperature reading without needing wires.

Kinda like this:

That's pretty cool!(though not non-invasive).   I did not realize those were available.  I'm trying to imagine their use other than research - none in medicine that I can think of.

Capsule endoscopy has been around for a while now and is very medically useful.

Totally feasible - that's what some of these pill things do, via radio .  -Ian-

Where would you suggest I take reading? I can't put it in the mouth.

Anal probe is the most accurate known method. 

I think a deep liver probe is considered definitive.

Not terribly comfortable though.

Not much imagination required since their website gives application info... Sports physiology (just like what you're trying to do), Firefighting, Occupational Safety and Military...

For the experiments you described this really does seem like the most sensible option, it's comparatively cheap and gives the most reliable measurement of core body temperature without any gotchas. In particular, as your subjects are going to be moving any external contact or IR sensor method is right out.

That's what I was going to suggest. Does the person need to stay alive after the reading? If not, the liver is the best bet.
