To my knowledge, there are no examples of convex imaging surfaces in nature.<br /><br />What would the lens for a spherical sensing surface look like? It seems like the only lens solution would be a single lens over each pixel, or a lens over a small group of pixels. I.e. a fly's eye. We already have technologies for assembling arrays of small cameras. I think USD10 now buys you a kilogram of 1/10" VGA cameras in Shenzhen. <br />Unknownhttps://www.blogger.com/profile/06164074033917462617noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-5477048866764203702017-11-27T06:10:58.629+02:002017-11-27T06:10:58.629+02:00Awesome, can't imagine how this innovation wil...Awesome, can't imagine how this innovation will affect the adjacent field.

To move to a more classic image sensor, there should be at least a switch in each pixel, complicating the fabrication and wiring. Perhaps that is next. I am not sure what the advantage of individual pixels wired together would be but maybe it could be more flexible. Passivation of the pixel sidewalls would be important. I think a cluster-based array makes more sense for flexibility and manufacturing, assuming there was an application for this. I did see an interesting presentation from a group of college students making a flexible array of solar cells. Different approach, but similar concepts, including DRIE for etch-thru.<br /><br />Stretchable Photovoltaics, University of Maryland<br />Team Members: Sabrina Michelle Curtis, Alexander Randolph, Gabriel Anfinrud, Haotian Wang; Advisors: Ray Phaneuf, Nathan Lazarus<br />Power Flex: Imagine wearing a traditional solar panel on your back. While useful for charging your smartphone, it's neither lightweight nor particularly comfortable. Now imagine a different kind of solar cell, one the thickness of a piece of paper and woven seamlessly into your clothing. This invention is a silicon solar cell with a unique serpentine structure able to stretch by 30 percent, just like human skin, opening a new era of wearable and renewable power generation.Eric R Fossumhttps://www.blogger.com/profile/09740612324630105312noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-81104288941679978402017-11-25T13:51:43.798+02:002017-11-25T13:51:43.798+02:00Amateur here: Would it be possible to have flat Si...Amateur here: Would it be possible to have flat Si pixels, each as a separate tiny piece and they would be connected with metal "wires" only? :) Small gaps in between.. and maybe you can bend it then!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-18782834177479396012017-11-24T23:10:34.337+02:002017-11-24T23:10:34.337+02:00fascinating techniques! fascinating techniques!
