Apps permit you to link your smartphone to something from your shoes, to your jewelry, to your push button — and shortly, you’ll be able to add your contact lenses to it list.
Engineers at the University of Washington have developed an innovative method of communication that may permit medical aids like contact lenses and brain implants to send signals to smartphones.
The new school, referred to as “interscatter communication,” works by changing Bluetooth signals into Wi-Fi signals, the engineers wrote during a paper which will be bestowed August 22 at the Association for Computing Machinery’s interest group cluster on digital communication conference in Brazil.
“Instead of generating Wi-Fi signals on your own, our technology creates Wi-Fi by victimisation Bluetooth transmissions from near mobile devices like smartwatches,” study author Vamsi Talla, a pursuit associate within the Department of engineering science and Engineering at the University of Washington, aforementioned during a statement.
Interscatter communication is predicated on AN existing technique of communication referred to as disperse, that lets devices exchange info by reflective back existing signals. “Interscatter” works basically identical method, however the distinction is that it permits for inter-technology communication — in alternative words, it permits Bluetooth signals and Wi-Fi signals to speak to every alternative.
Interscatter communication would permit devices like contact lenses to send knowledge to alternative devices, in step with the researchers. Until now, such communication had not been attainable, as a result of causing knowledge victimisation Wi-Fi needs an excessive amount of power for a tool sort of a lens system.
To demonstrate interscatter communication, the engineers designed a lens system equipped with a little antenna. The Bluetooth signal, during this case, came from a smartwatch. The antenna on the lens system was able to manipulate that Bluetooth signal, write in code knowledge from the lens system and convert it into a Wi-Fi signal that might be browse by another device.
And although the conception of “smart” contact lenses could appear somewhat gimmicky, they could, in fact, give valuable medical info to patients.
For example, it’s attainable to observe glucose levels from a human tears. Therefore, a connected lens system might track glucose levels and send notifications to a human phone once glucose levels went down, study author Vikram Iyer, a degree student in engineering, additionally at the University of Washington, aforementioned during a statement.
The researchers additionally aforementioned interscatter communication can be wont to transmit knowledge from brain implants that might in some unspecified time in the future facilitate individuals with palsy regain movement.
Not all of the potential applications area unit associated with medical devices, however. Interscatter communication might additionally exchange info between credit cards, the researchers wrote. this is able to permit individuals to transfer cash between cards by merely holding them close to a smartphone, for instance, they said.
