Microchips are examples of integrated circuits—chips of semiconducting material whose surfaces contain billions of circuit components wired together.
Hours of research by our editors, distilled into minutes of clarity.
Through anti-Stokes cooling, incoming energy is combined with vibrations in a material's crystal lattice to produce a net reduction in its temperature. Using this effect, lasers can be directed at microchip hot spots to help keep data centers cool.
The magstripe on bank cards always gives the same data, making it simple to copy using a device called a grabber. In contrast, embedded chips create a unique code with every transaction, making it much harder to clone or steal card information.
