Sony files patent for wearable computing 'SmartWig'

Sony has filed a patent for a "SmartWig," a replacement head of hair that also tracks the wearer's blood pressure, temperature and other metrics. The Japanese tech giant currently has no plans to commercialize the approach, but the patent shows it--like Google ($GOOG) and many others--is keen to enter the wearable computing sector. Such devices could be used for remote data capture in clinical trials. Article
