Preterm infants appear to mature better if they are shielded from most wavelengths of visible light, from violet to orange. But it has been a challenge to develop a controllable light filter for preterm incubators that can switch between blocking out all light - for sleeping - and all but red light to allow medical staff and parents to check up on the kids when they're awake. Now, in a paper accepted for publication in Applied Physics Letters, a journal of the American Institute of Physics, researchers describe a proof-of-concept mirror that switches between reflective and red-transparent states when a small voltage is applied.
