Not really "self aware", rather "condition monitoring"

Self awareness is a lot different from self condition monitoring. Machines that can keep track of their own condition are usually a good choice, while a "self aware" machine would probably be a real source of grief. A lot of machine condition monitoring can be added all in code, with no new sensors or other hardware, if the writer of the control code adequately understands how the machine should be working. Monitoring the time for each motion is a good exmple, it just requires an additional timer and a bit more code, and some usable means of announcing when some system starts to suffer from slower performance. Vibration sensing is a more complex task, and that would usually need a sensor dedicated to vibration monitoring.

Well within reach

Al, this type of functionality is well within reach.  In the early 1980s I worked on an R&D project at a simulation maker to do something similar.  Implementing it was more challenging that it would be today.  We had a mircoprocessor controller that was microcodable, so I made up some new instructions to do the analysis more quickly.  Today there is so much computing power and memory available that this technology can be added to almost any industrial system.  Many powerful S0C microcontrollers cost in the range or $1 per unit in quantity.  In most systems I have seen the sensor, whcih is often very specialized, is the more expensive component.  This is changing as well.  So, bring on the self-aware functionality.  Of course, you will need more software engineers to do that.

During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
It's been two years since the Mac Mini's last appearance on iFixit's teardown table, but a newly revised version joins Apple's lineup this week.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
