Scientists have developed a chemical based camera aperture system. Gone are the mechanical aperture blades that have existed, with this new development. The new aperture is chemical based, inside glass and is reactive to electrical currents. No more moving parts.
This new glass aperture works in the same way as the human eye.
At present, the limitation of this new aperture is response time, it cannot compete with the current metal aperture for speed, but no doubt the scientists will be working to overcome that.
