This is a CMOS IC (CD4033) based circuit which can be used to detect presence of AC mains voltage without any electrical contact with the conductor carrying AC current/voltage. Thus it can be used to ...

Nisshinbo Micro Devices has come out with a digital earth leakage current detector IC designed to enhance the safety and reliability of electrical systems by integrating advanced overvoltage and DC ...

North Carolina-based Hotstick USA has exclusively licensed a direct-current detector technology developed by the Department of Energy's Oak Ridge National Laboratory to help emergency responders ...

The growing number of plug-in electric cars, and also hybrids, as well as expanding solar market, leads to the topic of how emergency responders will be able to detect high DC voltage. One of the ...

Metal halide perovskites are soft-lattice semiconductors with inherent high ionic concentrations. Their X-ray sensitivities are several orders of magnitude higher than semiconductors such as silicon, ...
