It's an electronics issue. The optics get worse.

By curving the sensor many aberrations of a lens can be reduced, and lens design - substantially simplified.

No. Those are common misconceptions. Lens design for curved sensors becomes radically more complicated, and reduces no aberrations unless you employ some pretty radical curves. It's also essentially useless on interchangeable lens cameras (or zooms), as an arbitrary curve that worked well with one lens would worsen another.

I wonder if this ever scales up to large (4/3 to FF) sensors...

No.

This concept demonstration uses physical stresses on the semiconductor to alter its electrical properties: stressing bonds to make it easier to liberate electrons, increasing low light sensitivity. Anchoring the corners and putting pressure on the center is an easy way of creating stress and being able to vary it in a lab setting.

A production implementation would stress a flat sensor by chemical alterations of the surface, or by laminating a material with a different thermal coefficient of expansion.
