Platinum and ruthenium are in computers and in the glass of computer screen. Without PGMs, there would be probably no computer, no mobile phone, no wiki IGEM... Each hard drive contains one or more platters or disks where data is stored on the magnetic surfaces. The strength of the magnetic field generated by the surface layer determines how much data can be recorded on a given surface. Adding platinum to the cobalt magnetic alloy enhances the magnetic properties of the surface and therefore its storage capacity.

Platinum, palladium, rhodium and iridium are used to coat electrodes, the tiny components in all electronic products which help to control the flow of electricity. Palladium is contained in most microprocessors and printed circuit boards. Platinum is used to make fiberglass, liquid-crystal display (LCD) glass and flat-panel displays, and cathode ray tubes. PGM equipment is used to make ceramic glass.
