A new type of chemical iris camera designed for smart phones has been successfully developed by researchers in Germany. Traditional cameras use mechanical plates to change the size of the aperture through which light enters. The new micro-iris feature makes it opaque when passing a small voltage. Ultra-thin devices can stimulate the development of a new generation of mobile phones and tablets. Variable valve timing (VVT) solenoid or oil control valve controls the oil flow according to the engine speed and load. VVT solenoid is a vital part of the variable valve timing system.

The principle of electrochromic iris can be used to control transmitted light and depth focus. In the human eye, the iris camera controls the amount of light reaching a sensor to affect the overall image. The device is made of two glass substrates sandwiched together, each carrying a film with electrochromic polymer PEDOT attached. The potential of the iris lies in its current state, which is mainly a comparison of commercial PEDOT materials that absorb light and have relatively short switching times.
The Oil Control Valve (OCV) is a a critical part used in every engine that is fitted with variable valve technology (VVT). A single control valve will regulate the supply of oil to a designated VVT hub, to advance or retard the timing by altering the camshaft angle position. Controlled by the ECU, the OCV receives electrical signals, instructing it to adjust the oil flow as required, in accordance to current driving conditions.
