Sensors and the applications that can run on them were the main focus of startups at SmartCamp, a global business plan contest sponsored by IBM. Ten years ago, companies like Dust Networks and Intel were showing off prototype applications for the “extroverted computing” market, a term I made up in 2003 that failed to catch on. SynapSense and others brought sensors to the data center a few years ago while APS today said today that it planned on inserting sensors into its grid for monitoring and self-healing applications. Now, other applications are coming to market.
