Islamabad\u00a0\u00a0 –\u00a0 The advance could cut production costs and reduce the size of microelectronics for sensing and\u00a0communication. Light-Emitting Diodes (LEDs) can do way more than illuminate your living room. These light sources are useful microelectronics too.Smartphones, for example, can use an LED proximity sensor to determine if you\u2019re holding the phone next to your face (in which case the screen turns off). The LED sends a pulse of light toward your face, and a timer in the phone measures how long it takes that light to reflect back to the phone, a proxy for how close the phone is to your face. LEDs are also handy for distance measurement in autofocus cameras and gesture recognition.One problem with LEDs: It\u2019s tough to make them from silicon. That means LED sensors must be manufactured separately from their device\u2019s silicon-based processing chip, often at a hefty price. But that could one day change, thanks to new research from MIT\u2019s Research Laboratory of Electronics (RLE).Researchers have fabricated a silicon chip with fully integrated LEDs, bright enough to enable state-of-the-art sensor and communication technologies. The advance could lead to not only streamlined manufacturing, but also better performance for nanoscale electronics.<\/p>\n","protected":false},"excerpt":{"rendered":"
