An active artificial iris controlled by a 25-mu W flexible thin-film driver

{We show an active artificial iris based on solely thin-film components, wherein several LCD elements are controlled a metal-oxide TFT and by powered by thin-film photovoltaics (TFPV). Key aspects for the driver are size and low power consumption. We demonstrate power consumption down to 25 mu W for the full iris.}
