Light-emitting diodes are the future, and will quickly bypass government-mandated and subsidized compact fluorescent bulbs and the prospect of wearing a Haz-Mat suit if you break one. Why be limited to bulbs, though?Why not a light-emitting fork? Physicist Amir Asadpoordarvish of Umeå University in Sweden did just that, using new light-emitting electrochemical cells (LECs) sprayed onto a substrate that emit light using the current from an ordinary battery. A LEC is a solid-state thin-film device, which comprises an active material sandwiched between a cathode and an anode as its key constituent parts. To-date they have been fabricated on heavy, rigid parts. read more
