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.
