Anyone know what these sensors are?

It's time to dust off those old lenses that have been sitting around in your junk drawer.

Given that there's no CFA - color filter array - then the advantage of not being a
scanning back, for which one is paying $106,000 expected price - is somewhat
negated by having to take three exposures. So there's still a problem for subjects
that move.

I think they make a colour version, maybe not. I was more interested in who made the sensors, a bit more on the tech behind them.

The fact that it is only a 12 megapixel sensor - a number of pixels that is
present in conventional sensors - would seem to suggest a different technology,
but the high price tag suggests a giant CMOS or CCD sensor.

Ah, this site

claims it's a CMOS sensor.

So I suppose the innovative tech is to have multiple pixels in each large pixel
so that there is fault tolerance. This is, after all, a wafer-scale sensor.

Maybe, but I'll bet they are single 75 um pixels. On the whole, I'd
say this product is pretty much a gimmick for people with too much
money. Some of the claims are just nonsense (3D like feel from a large
sensor). Mostly, there's just no obvious advantage to such a large
sensor with such large pixels. It provides no better resolution than
any good DSLR (worse, in fact). Large format lenses are expensive, and
designed to have much better optical resolution than the large pixels
allow for, so you lose much of the advantage, but still pay the price.
Big pixels can provide large dynamic range, but this device doesn't
seem to have better range than modern DSLRs (they claim 16-bit, but
I'll bet the actual S/N is still in the 12-14 bit range).

Theory goes back to film, less enlargement equals higher quality. In fact, one trick is doing mosaics with a longer lens and stitching them. That's for resolution. BUt I wonder what the low-light performance would be like with 75um pixels?
