If that isn't enough to boggle your mind, check out the links on
this Google results page that came up when the key words "radiation hardened electronics" was used as the search string. It's not just about about bullets and mayhem anymore: it's tough to survive, much less reliably operate, in outer space, or near the un-shielded core of a nuclear fission reactor, or in the near vicinity of a high-energy particle accelerator, but it's nevertheless necessary for instrumentation and control purposes to do just that. And don't even ask what is required to get approval to use an electronic device for medical purposes, where threat of failure could jeopardize human life. The CYA paperwork is enormous, even assuming you can actually get a manufacturer's permission and approval.
Well, I certainly hope that Medtronic used really good and approved parts in my heart pacemaker/defibrillator. I go in Monday afternoon for a wireless diagnostic scan to find out if it is still working properly and for an estimate of the remaining (non-rechargeable) battery life. The surgeon who implanted this thing in Dayton, OH, on 29 April 2015 neglected to include a zippered incision closure that would allow easy battery/device replacement. Nor is it a high-end implant that can be inductively charged by placing a coil on my chest. Of course I am not at all sure I would even
want a Li-ion battery implanted in my body. If I live long enough to require at least one more device swap, I figure I'm ahead of the game. Two or more swaps and I would be pushing a century of living under the threat of death... but aren't we all in that boat?
Now,
@Uma maheshwari, go design something reliable that will eliminate the need for war and advance the agenda of world peace. Cost is no object for this project, but time is of the essence.
