SenseWear
The SenseWear Armband by BodyMedia is a physical activity monitor meant for use by patients whose doctors wish to track their movement outside the office.
SenseWear contains an accelerometer to measure motion and steps, a galvanic skin response monitor to measure the electrical conductivity of the skin, skin temperature, and heat flux - the amount of heat dissipating from the body.
SenseWear holds up to 28 days of data, which can only be analyzed on the SenseWear Professional Software package.
