A new micro-iris features 55µm thick transparent chemical rings of electrochromic polymer PEDOT (poly 3,4-ethylenedioxythiophene) which turn opaque when 1.5V is applied. The obvious application is in front of CCD cameras in phones but it has other applications.

    The switching time from transparent to opaque (well, 40% opaque, anyway) is around 15 seconds and 2 seconds back to transparent. That's a long time in a camera. My cell phone already has more lag than is convenient. "Sweetheart, hold still while I [push button] take this picture........[click]. It might be better in surveillance cameras and the like, something that usually doesn't need to react quickly.

    But if you are using this to adjust the f-stop I would take a 15 second delay to set everything up and then snap quickly. It's not going to change between shots.
