Front Cover: A flexible OPD with high properties for applications (Laser Photonics Rev. 8(2)/2014)



Low-voltage-control circuit is one of themost important parts of the modern electrical control system due to the avoidance of operation risk and easy automation. A flexible organic photodiode (OPD) is explored for the development of flexible low-voltage-control circuit under 2000 V high voltage. This sort ofOPD has a promising application in low-voltage-controlled, high-voltage-endurable hands for intelligent robots.
