A team of engineers from University of Washington in Seattle, including the Indian-origin researchers have been successful in finding a new way to communicate among devices, such as the smart phones and watches, bringing hope for internet-linked wireless implanted devices.
The Wireless implanted devices comprise brain implants, contact lenses, credit cards and smaller wearable electronics. The new communication system called as the ‘interscatter communication’ makes communication possible by transforming Bluetooth signals into Wi-Fi transmissions over the air. In this type of communication, an interscatter device such as a smart contact lens uses only reflections to transform Bluetooth signals from a smartwatch, for instance, into Wi-Fi transmissions that can be received by a smartphone. These Bluetooth devices randomise data transmissions by employing a process named scrambling. Moreover, the system does not require any specialised equipment and relies only on mobile devices generally found with users to generate Wi-Fi signals using 10,000 times less energy as compared to conventional ways.
Vikram Iyer, electrical engineering doctoral student, stated that wireless connectivity for implanted devices can change the way to manage the chronic diseases. The Indian-origin researcher also illustrated his point with an example that a contact lens may be able to monitor a diabetic’s blood sugar level in tears and send notifications to the phone as soon as the blood sugar level decreases.
Vamsi Talla, co-author of the study, stated that their technology creates Wi-Fi by employing Bluetooth transmissions from nearby mobile devices such as smartwatches rather than generating Wi-Fi signals on their own.
The further details of this new technique were presented at the annual conference of the Association for Computing Machinery’s Special Interest Group on Data Communication (SIGCOMM 2016) in Brazil on 22 August 2016.
