Due cose molto interessanti, la prima a livello fisico e la seconda elettronico:
1) What if we could work with the field curvature inherent in lenses, as opposed to against it? That's exactly where curved sensor technology can help. Curved sensors allow simpler lens design, since light rays entering the lens from oblique angles don't have to be corrected to project onto a flat surface. They also combat peripheral light fall-off by improving light collection at the edges of the sensor, since the light enters the photosites at a less oblique angle (back in the days of film, this sort of fall-off was somewhat mitigated due to the fact that film dyes were more accepting of oblique light rays than deep pixel wells are). In fact, a 2x increase in photon collection efficiency is reported for the periphery, with a 1.4x increase in sensitivity in the center of the sensor as well. The latter may be due to a better ability to collect oblique light rays entering the peripheries of the lens. All of this means that there's a potential for the use of faster, brighter, simpler lenses without the significant peripheral sharpness and light fall-off we've become accustomed to.
2) Sony also found that the bending process improves the sensor's fundamental performance. The strain introduced into the sensor upon bending widened the energy band gap and decreased dark current (residual electronic signal present in the absence of any external light). Both of these achievements should contribute to increased image quality.

Indubbiamente un sensore che copia le fattezze umane potra' dare una sensazione piu' vicina a quelle reali, leggendo l'articolo di dpreview di capisce come sia molto interessante dal punto di vista applicativo questa tecnologia.
Strano che nessuno ci abbia pensato prima...anche se c'e' da dire che sul web si trovano tracce di brevetti Sony risalenti a due anni fa, quindi si vede che non era proprio semplice la realizzazione...anche perche' "nessuno" si mette a realizzare chip curvati...immagino i casini tecnologici per realizzare un qualcosa di funzionante.
