United States developed the world's smallest monitor installed in the contact lens

Despite the commercialization remains to be seen, but it is combined with virtual reality on the important step. Recently, the University of Washington scientists ????? Chavez with his research - a display function of contact lenses, held in Beijing participated in Electrical and Electronic LTC1065CSW Engineers Biomedical Circuits and Systems Conference (IEEE BioCASE 2009) . The virtual world can be superimposed on the real picture on the latest technology, is expected to give the user unprecedented wonderful experience. U.S. scientists have developed this display can be worn on the eyes, to monitor and contact lenses combine together cleverly. He built a tiny contact lens in the LED display, mobile electronic devices can be images and text directly onto the glasses to get rid of the notebook computers, mobile phones and PDA and other mobile information device limitations. Parviz hope, the device can show a large number of images in the user front 50-100 cm distance, so that the virtual world of all types of information in the real reach of the Department will be able to view at a glance. In the development process, how to use the eye-friendly materials to produce the circuit and combined it with contact lenses, as researchers face a great challenge. Good use of nano-biotechnology and nano technology manufacturing small electronic assembly equipment Parviz designed a special set of circuit elements, and creative use of capillary action to the circuit assembly, succeeded in solving this problem. The polymer used to make lenses for not STV5730A-1 withstand high temperatures and fine chemicals used in processing the case, he diameter of only 1 / 3 mm LED circuit elements such as specially designed pre-installed on the organic substrate with a biocompatible . In the contact lens surface is first made with metal wire circuit, and etching out the shape of each component compatible with the hole, and then let the liquid spread on the surface of contact lenses, and the erection of these free components placed into the liquid. In the capillary force, the components according to their shape embedded in the lens surface corresponding slot gap, completing the circuit of subtle self-assembly process. Another challenge facing scientists is how to contact lenses for micro LED power supply. Parviz originally designed in two ways: one is through installing the antenna in contact lenses, and receive radio waves to produce energy; the other is to use photovoltaic cells. After several months of research, the scientists chose the former, and success. However, Parviz still need to continue to improve the transmission of information and power, he hopes that both will be supplied by mobile phone. British "Guardian" reported in 2008, this was still in the development process of electronic circuit with a light-emitting diode (LED) of the contact lens much appreciated, that the study, if successful, will be the most minor personal monitors. The combination of reality and virtual tremendous progress in any scientific and technological progress have a cumulative process, the development of personal monitors is no exception. As early as 1968, the U.S. Defense Advanced Research Projects Agency (ARPA) Information Processing Technology Office, Ivan Sutherland at MIT's Lincoln Laboratory developed the first helmet-mounted displays - "The Damocles AD9850BRS sword. The use of cathode-ray tube mounted display for the first time a virtual extension of people's vision, the user can see superimposed on the real environment on wireframes later the technology is widely used in fighter pilot helmet and virtual reality devices. Since then, scientists have been constantly improving the display, to make it lighter, clearer images. To June 2009, the German Fraunhofer Institute for optical micro-system scientists developed the optical display. Scientists put a CMOS sensor and a tiny projector into the OLED to a very small chip, and then install the chip on the glasses. After receiving instructions, micro-OLED projected images will be projected onto the wearer's retina, allowing the wearer to see high-resolution and high-resolution images, and feel their image at a distance of one meter distance. The chip also comes with eye tracking capabilities, through tracking the wearer's AD73360LARZ eye position to determine the wearer's command, greatly enhancing the interactivity of the display. And now, Parviz nanotechnology developed to monitor worn on the eyes. The micro-display applications bright future. In the field of so-called augmented reality, that is where all the required supporting information, such as navigation arrows, building descriptions, graphics or language translation, operating instructions, can be widely applied. In this regard, New Zealand University of Canterbury expert assessment of augmented reality ????? Manchester said: "A contact lens will be the real world and virtual graphics seamlessly link up, this is a huge step forward, although this idea to achieve business technology remains to be seen, but this prototype is in this direction an important step.
