Package-tracking sensors aren't super new, but Senseaware is one that's unique because it tracks multiple criteria - temperature, location, drops and light exposure - and updates those to the web constantly. Useful when you're transporting organs and not MP3 players.
Senseaware is going to be using these sensors in the medical transport field, who distribute organs on a regular basis, and offer it as a simple drop-in addition to the package. How this affects you is that FedEx is working on lowering the price so that not-so-essential packages can also get the same detailed tracking. [Fast Company]
