Good point, Ann. You bring up somethign perhaps I didn't stress enough, the ecological factor. This solution is definitely more environmentally friendly. Batteries--while very important to our lives and a great invention--also are a great source of pollution, as you mention.
@tekochip,That's a good question. I was thinking of sending this link to our local wildlife biologist to suggest watching for further developments in wildlife tracking using energy harvesting. One of his greatest frustrations is having a battery run down on an animal he has tracked for years. There are tracking devices that use solar energy but this device offers new possibilities. As you point out, animals don't care about RF zones.
I first became aware of the possibility of harvesting RF when I took a Design News Digi-Key class in April 2013 on Energy Harvesting taught by Paul Nickelsberg.
I believe the gesture detection uses harvesting, but transmitting the gesture still requires power. It's really an interesting idea, I wonder if it's very mobile? I would think moving the device from one RF environment to the next would change the device's sensitivity.
Oh, I see you are already ahead of me, Daniyal! I just posted this story in a comment on the story about Ring. So ignore that! But I am glad to see you are impressed. It does seem a little more user-friendly than the ring, and if it's not too expensive to get more than one for different devices, then I think it's probably definitely worth it.
"This is the first gesture recognition system that can be implemented for less than a dollar and doesn't require a battery."
Amazing technology Liz. When i read your blog, the first thing that came into my mind was the price of this device, as i was expecting it to be a bit expensive. Turns out, it's not only without batteries but also very low-priced. This will certainly boost the research being done on battery free technology. I always imagined a world without batteries and getting rid of all the trouble of charging and discharging. It looks like the time is near. Hoping to see the integration of this device with maximum number of appliances we use in our daily lives. I would love to control everything i own, with just the movements of my hands.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
