Scholarly literature feeds or alerts may be set up in most engineering databases. In Scopus, for example, you can perform a search and then set a feed or alert:
In Web of Science, first sign into Web of Science (create an account if necessary), then click on Create Alert to save the search history. You can choose to have email alerts sent, and/or create an RSS feed.
Many engineering associations, such as ASTM and AIAA (as well as others), have RSS feeds reporting on publications and news. Go to the home page of the organization and look for the RSS icon.
It is possible to set up feeds for patents, so that you can see all the recent patents or patent applications in a patent class. For example, see FreePatentsOnline (http://www.freepatentsonline.com/rssfeed.html).
