Light-emitting diode From Wikipedia, the free encyclopedia
... Like a normal diode, the LED consists of a chip of semiconducting material impregnated, or doped, with impurities to create a p-n junction. As in other diodes, current flows easily from the p-side, or anode, to the n-side, or cathode, but not in the reverse direction. Charge-carriers—electrons and h ...

... converter by using a family of the charge-averaging type converter. Different from conventional converters, the proposed converter provides only Q/P (P ∈ {2, 3, . . . , N } and Q ∈ {1, 2, . . . , N − 1}) stepped-down voltages. However, the number of power switches for the proposed converter is less ...

Flexible electronics
Flexible electronics, also known as flex circuits, is a technology for assembling electronic circuits by mounting electronic devices on flexible plastic substrates, such as polyimide, PEEK or transparent conductive polyester film. Additionally, flex circuits can be screen printed silver circuits on polyester. Flexible electronic assemblies may be manufactured using identical components used for rigid printed circuit boards, allowing the board to conform to a desired shape, or to flex during its use.
