A tiny three-phase motor invented by Swiss researchers could be used to power a new generation of wristwatches, allowing them to work as mobile phones, app devices and GPS units. Those activities generally require plenty of power, which can be cumbersome and costly — but a new microelectromechanical system will keep them juiced.
Researchers at the Swiss Federal Institute in Lausanne came up with a small electromagnetic three-phase motor that yields three times the energy output of a traditional motor.

Despite my geeky leanings, I've typically run with tech no more complex than an Ironman watch. But in the spirit of the title of this column, I've recently been testing a number of sports watches, from Suunto, Polar, and Garmin, to see if I could gain anything from monitoring my effort (or lack thereof). So far, the one device I find myself frantically searching the house for before I head out is the new Garmin Forerunner 405CX. And not for what it puts on my wrist, sleek as it is, but for what it puts on my monitor later.
