When did swallowable tiny robot gear become the breakout single of the summer? We're not sure (ok, so maybe it's not that popular) but first there was the robot pill crawler, now the latest is the VitalSense monitoring pill. Designed by the Mini Mitter Company and, um, the US Army, the pill checks out your inner stats with a wireless temperature sensor. We can feel a Survivor-type reality TV cameo brewing here, but more practical apps include studying how high-heat environments affect body stress. We're thinking of popping a few, relaxing at the fake-n-bake, and checking the results.
