Researchers at the University of Washington have been working for years on a radio backscatter system that can monitor ultra-low-power sensors wirelessly, and now they’ve fine-tuned the system to pick up signals from more than a mile away.
They say the technology could lead to “smart” contact lenses and skin patches that can track your vital signs and send in the data for instant medical analysis.
And that’s not all: Long-range backscatter sensors might well open up whole new frontiers for the Internet of Things.
“People have been talking about embedding connectivity into everyday objects such as laundry detergent, paper towels and coffee cups for years, but the problem is the cost and power consumption to achieve this,” Vamsi Talla, chief technology officer of Jeeva Wireless, said today in a UW news release. “This is the first wireless system that can inject connectivity into any device with very minimal cost.”
Jeeva Wireless, which was founded by Talla and other UW researchers, is aiming to commercialize the technology within the next few months.
