The Theremin, as you will know, is a musical instrument usually controlled by moving your hands around one or more antennae. However, any body part should suffice.
Given the hugely increasing smallness of electronics, and improvements in battery technology, it should be possible to incorporate the necessary components (including a small piezo speaker) into an IUD. Once this is done, applications of this technology will doubtless be discovered.-- MaxwellBuchanan, Feb 02 2017 I thought you were saying incorporate it into an IED. That would be slightly less odd.-- AusCan531, Feb 02 2017 I assumed that [8th] would cover that one.-- MaxwellBuchanan, Feb 02 2017 It might produce hysteria.-- not_morrison_rm, Feb 03 2017 I don't think I have ever been so confused, and that's after contemplating Trump and Brexit for over a year.-- po, Feb 03 2017 The trick, obviously, would be to get a tune out of it.-- MaxwellBuchanan, Feb 03 2017 Inspired, but wouldn't it just be going off continuously, what with physical contact etc. Worth the experiment in any case.-- tatterdemalion, Feb 04 2017 I think the firmware (pun intended) could be programmed to null-out routine contact, leaving the thereminiud to respond solely to, ah, additional stimuli.-- MaxwellBuchanan, Feb 04 2017 I thought that this was nude theremin, and the lead in reference to body parts made sense. But the increasing smallness bit seemed unusually self deprecating for Max. I assumed a cold day in the UK.-- bungston, Feb 04 2017 Pah. I'm not called Max for nothing.-- MaxwellBuchanan, Feb 04 2017 random, halfbakery
