From Nike+ Fuelband to Jawbone Up, there are plenty of small motion-based gadgets available, but the latest device uses technology that measures more data than ever. Like its competitors, Basis ($199) has a three-axis accelerometer that detects steps. But unlike other health bands, it includes sensors that measure optical blood flow, perspiration, and skin temperature. The band's software finds opportunities to insert healthy habits gradually over time, stressing consistency with steady and systematic "take-charge actions."
