Imagine a device that fits inside a pair of shoes, harvests the energy leftover from walking and stores it in AAA or watch batteries. At the Center for Research in Advanced Materials (CIMAV) in Chihuahua, Mexico, scientists have done just that.
Despite their relatively high upfront cost, light-emitting diodes (LEDs) are consistently hailed as the next generation of efficient lighting technology. Most experts agree there is no question that LEDs will take the lead in general service lighting.
Among the industries seeking ways to make technology smaller, lighting is no exception. Now, a team of scientists at the University of Strasbourg in France has developed the first single-molecule light-emitting diode (LED).
It seems like, every other week, a leading research lab announces a breakthrough technology to make batteries more powerful, more durable or a whole lot less expensive—after just a few more years of research and development.
Some industry observers have predicted that solid-state lighting technology (SSL) will satisfy most lighting applications by the end of the decade. One particular SSL technology on the cusp of commercialization has the potential to be transformational: the organic light-emitting diode (OLED).
