What If Your Contact Lens Could Tell Your Smartphone Your Blood Sugar Was Low?
It may well appear like a page from a sc-fi novel, however researchers at the University of Washington if have their way, implanted/inserted electronic devices may be able to change healthcare sector. Envision an equipped contact lens that would be able to gauge a diabetic's blood sugar level evaluating tears and send out signals/notifications to their smart phone/device whenever their blood sugar increases and/or decreases in order to react to the changes.
An innovative approach, dubbed interscatter communications reads wireless Bluetooth impulses into Wi-Fi signals over the space with reflections of pre-existing impulses, making it possible for the inserted/implanted electronic devices to communicate with smart devices like phone. The scientists express hope in the potential to make implants communicate with your smart devices like a phone or watch.
Due to their size, tiny implants within the body are limited by energy needs and cannot therefore send out signals using regular conventional wireless means. But with the scientists interscatter communication technique, Bluetooth or Wi-Fi embedded in a cell phone, smart watch or headset, can serve the dual purpose as both a origin and receiver for reflected signals.
In recent demonstration, a paper reviewed at the annual conference of the Association for Computing Machinery's Special Interest Group on Data Communication (SIGCOMM 2016) in Brazil, the scientists utilized a smartwatch to broadcast a Bluetooth signal to a smart contact lens with an antenna. The researchers devised a unique strategy that turns the Bluetooth signal into a "single tone" signal that can be further manipulated and changed. The single tone signal let the contact lens encode data it gathered into a regular Wi-Fi packet the smartphone can read.

" how to lower blood sugar fast for equipped devices can change the manner we treat chronic diseases," said Vikram Iyer, a University of Washington electrical engineering doctoral student and co-writer of the paper. "Instead of generating how to lower blood sugar fast -Fi signals on your own, our technology creates Wi-Fi by using Bluetooth signals from nearby mobile devices such as smartwatches."
