Corning develops smart glass to introduce biotechnology detectable DNA
Release date: 2014-09-03
Recently, Corning is developing a smart glass that can analyze the liquid on the surface of the screen without any external medical equipment, thereby detecting the user's physical condition and DNA, and even monitoring the air content in the air.
In the future, if someone spits on his or someone else's mobile phone screen, he may not be a snake, he may be taking a cell phone to measure DNA. Corning is currently developing a smart glass that analyzes the surface of the screen to detect the user's physical condition and even detect the user's DNA without the need for any external medical device.
Wave Guide: Integrated Circuits in Glass
Corning, a manufacturer of Gorilla Glass, used in many smartphones, recently developed a smart glass with Montreal Institute of Technology in Canada that analyzes the surface of the screen without the need for any external medical devices. Liquid, which detects the user's physical condition and even detects the user's DNA. In addition, this material can also monitor the amount of gas in the air.
This type of screen mainly uses a short-wave laser that integrates the Wave Guide into the glass without visible to the naked eye, and creates a "sensor" inside the glass through other tiny lasers.
The development team currently uses waveguides to create two sensors, one for real-time temperature measurement and one for identity authentication. The temperature sensor measures the body temperature by the user touching the screen. The authentication system first writes a piece of code on the glass, reads it through an infrared camera, and uses facial recognition technology to authenticate the user.
There are many more applications for waveguide technology, such as analyzing liquid components and even DNA through the surface of the screen.
The rise of wearable devices is mainly due to the need for health monitoring. This technology transfers the monitoring of bacterial content in saliva or the analysis of blood glucose levels to the screen of a mobile phone without the need for any smart accessories, which is more convenient than wearable devices.
Corning announced the technology at this time, probably because Apple is actively developing sapphire screens, threatening the position of Corning's screen brother, and hopes to regain Apple support with new technology. However, this screen is still in the research and development stage and will not be available until a few years later.
In addition to molecular testing, Corning has also developed antimicrobial glass.
Studying mobile phone screens with antibacterial properties
Jeff Evenson is a senior vice president and operations director at Corning, where he presented a short technical presentation on MIT TechnologyReview's MobileS ummit. In his presentation, Evenson conducted a control experiment: two pieces of glass covered a lot of E. coli, one of which was standard glass and the other was glass using antimicrobial technology. After 30 minutes, the number of bacteria on the antimicrobial glass decreased, and the bacteria completely disappeared after 2 hours, while the number of bacteria on the standard glass did not show any change.
Evenson said that he wanted to use the technology in the health care industry, but later read a report on the number of bacteria on mobile devices and decided to use it to help more consumers. Studies at Stanford University and the University of London have shown that E. coli and the like are present on the touch screen.
Evenson did not provide more details on the technology, and the time to market was unknown, only knowing that it would be within two years. If you are really scared by the dirtyness of your phone, you can use an anti-bacterial screen cleaning cloth. Another friendly reminder: wash your hands frequently, do not use your mobile phone or tablet in the toilet.
Imagine a future smartphone display that will detect if you have a cold or even analyze your DNA.
Researchers from the Polytechnic Institute of Montreal and Gorilla Glass manufacturer Corning have collaborated to develop display sensors that can analyze saliva.
The sensor is embedded in the display of the smartphone and can be used by the user to measure temperature and assess blood pressure (if suffering from diabetes). In theory, it can be combined with some platforms, such as Apple's homekit, to bring more real-time health information to users.
Despite rumors that Apple may abandon the Corning Gorilla glass screen for the iPhone 6 (and replace it with sapphire crystal), this technology may be the reason for Apple's insistence on Corning.
Reading the journal Optical Report details the research team's creation of the so-called first laser light guiding system that can accelerate progress.
Raman Kashyap, a co-author of the paper "Now We Opened Pandora's Box," Professor of Electrical Engineering and Engineering Physics at the Montreal Institute of Technology, said in a statement. Since it is technically feasible, "it depends on people creating new uses for it," he added.
The prospect of this technology is that biotech companies can embed these biomedical sensors into other devices, such as windows and desktops. To make this possible, the researchers sent laser light into the glass to create a path for transmitting data in the form of small beams of light. The waveguide acts as a channel to direct light, similar to a wire that carries electrical signals.
By adding these waveguides to mobile phones and adding readable code, manufacturers have opened up opportunities to be creative. Although the waveguide is not a new form, the researchers believe that the new form created by the research team has at least a 10x reduction compared to previous laser-based devices, Corning said.
There are also cases where the sensor is used to monitor the amount of carbon dioxide in the air and increase the safety of mobile equipment.
Currently, temperature sensors and certification systems are pending patent applications.

Steroids are a class of lipid soluble hormones. In the maintenance of life, regulating sexual function, body development, immune regulation, skin disease treatment and birth control has obvious effect. Steroid hormones are mainly used for: anti-inflammatory and anti-allergic; Treatment of male and female diseases and contraception; Improve metabolic function. Major side effects: more significant damage to the liver, and female masculinity. Long-term or a large number of use will appear acne, hairy, atrophic lines, purpura, osteoporosis, femoral head necrosis.
