Looking to keep watch on a few more vitals than something like the Fitbit provides? Then you might just be a candidate for this all-seeing, all-knowing "human recorder system" developed by a group of researchers from the University of Tokyo, and now offered by the non-profit WIN Human Recorder Co. Unlike the Fitbit, you have to affix this one directly to your chest, but that will let you monitor things like heart rate and body surface temperature in addition to movement with the aid of a three-axis acceleration sensor. What's more, you'll also be able to keep continuous watch on all that data via your cellphone of computer, but that won't exactly come cheap -- the sensor itself runs $330, to which you'll also have to add $110 a month for the monitoring service.
