Though made for a different market, designs may be applicable for experimental purposes.
And, yeah, I know. Not suited to shoe-string operations, either. Who knows, though. Maybe one of ’em wants a lock on design-in?
I’d certainly talk to the folks. They do this bread & butter, so they might be able to steer you in a good direction on this… And if they’re trying to sell you something, what boots it? Explain the problem, listen politely, and maybe they’ll connect you to an engineer who just breathes this stuff. HE may have an interest, and a bench to crank out some test articles.
These folks can smell a paper, too. A by-line on a ‘how I did it’ article appearing in an industry-specific rag wuld be good for everyone.
