Re: Lag of battery technology
@ Rich: Thanks for sharing the information. This is exactly what I wanted to point to. If chemistry is directed well, new dimensions would appear. Unfortunately, I do not notice satisfying development in this area.

Re: more cost effective
Yes I have read the article and its very interesting and the Walden pond is very great that he had introduced us with such a technology and one big salute to him .

Re: Lag of battery technology
You're probably right, L2. Big batteries is where we'll see the next breakthrus. Holds promise for the electric car to become more affordable that the big batteries will improve.

Re: more cost effective
Excellent article and really speaks to us.

We have a battery free integrated system "GreenPatch" that is batteey free and measures temperatire and occupancy and sends the data wirelessly for further  ation or sent back fir actuation.

Here is more infpormation about it:http://optixtal.com/optixtalwp.htm

 

(The "wp" at the end of our link is our salute to Walden Pond and the "self reliance" that we tnink it signifies.)

Re: Lag of battery technology
Interesting, but probably for big batteries - the last line of the article suggests a typical residential electrical service will be taxed to charge the structure described. Also, they say it isn't quite a supercapacitor, and isn't quite a battery, in terms of charge/discharge rates. They have addressed recharging and safety in their thinking. Like I said, I think the first breakthroughs like this one will be for EV batteries.

Re: Lag of battery technology
Kareem, Here is a link to some battery technology that uses nanoporous materials and promises exceptional energy density:

Re: self-powered wireless sensor
I am sure that the sensor would generate electricity by any way that information I have seen is that the system would change the proton into electricity this can be done easily and as the result we get the small amount of enery which is enough to make the sensors run .

Re: Tesla's dream?
Might be a little different. Tesla's dream was for energy delivery, this is for signal sensing and transforming using wireless energy.

Re: bridge sensors
This is really useful in Wireless Sensor Networks where ultra low power is needed. This SoC solution with energy harvest integrated will be an ideal device. Like it.

Re: self-powered wireless sensor
Thanks for the great technical detail. I especially appreciate the warning about providing some form of energy storage to take out the spikes.

SDN's Explicit Forwarding & IoT Security

9|12|14   |   1:52   |   (0) comments


SDN uses a central controller to decide what packets can be forwarded, so it could absolutely control access to IoT elements and provide a high level of security. The problem is scalability; we can't prove based on current usage that SDN could scale to large numbers of sensors and valid users. A second model may be needed.

IoT Design & the Control Loop

9|8|14   |   2:01   |   (0) comments


Any sensor application has a path from the sensor through a process point and back to the action point, often called a control loop. You have to pay attention to the length in milliseconds of this path or you risk getting so far behind the thing you're controlling that your application will be useless.

Wearable Tech, IoT & Authenticity

9|8|14   |   1:57   |   (0) comments


Wearable tech could be combined with IoT to create useful applications from tracking food/beverage nutrition to identifying the store with the best price by looking at various storefronts. To make it work, though, we need to be sure that what IoT provides is authentic, reliable information on which we can base decisions.

SDN & IoT: It's Complicated

9|8|14   |   2:00   |   (0) comments


SDN and IoT have some potentially significant natural symbiosis, but not necessarily in the ways everyone is talking about. Two things of special interest are the notion of a "Control and Sensor Network" built on the model of content delivery networks, and IoT security based on SDN principles, both topics to be covered in future vblogs!

3 Dimensions for IoT APIs

9|8|14   |   2:03   |   (0) comments


Developers building IoT apps will need APIs that expose IoT assets in three dimensions: geographic area, subject-tracking, and by-sensor-type. All these APIs will have to accept "credentials" so that data can be filtered by the privileges of the requestor. If all this can be done, we can count on rich IoT apps.

How Can We Help Stamp Out IoT Hype?

9|8|14   |   2:10   |   (0) comments


IoT, like most tech these days, seems to be all about hype. We can help realign things by focusing on what matters, which is not what you do in an application sense, but what technology models you expose to related IoT components and users with needs.

Another IoT View: Correlation & Context

8|27|14   |   2:16   |   (0) comments


The IoT can be viewed as a network of devices, as a web of information, or as a bunch of correlations that provide context for what we do and see. Taking this last view might help create more IoT value, guide us toward low-apple missions, and focus us on the real security concerns.

IoT, PnP & DIY

8|20|14   |   2:07   |   (0) comments


Traditional sensor networks don't put low-level elements on the Internet for cost reasons, but smarter on-net elements for home and process control could make the IoT a lot more accessible. In the end, it may be worth the extra cost to get extra participation.

Matching the Cloud & IoT

8|15|14   |   2:04   |   (0) comments


The cloud, using tools already available from providers, could offer significant value-add in IoT applications, particularly in making data available from a large, diverse set of sensors and turning that data into big-data/Hadoop repositories or workflows.

IoT & the 'First Telephone Problem'

8|15|14   |   2:06   |   (0) comments


You can't sell the first phone, the saying goes, because there's no one to call. The IoT may face a similar bootstrap problem. The solution may be to focus on placing sensors on the objects that interest us, adding environmental sensors as we build the business case.

New Single-Board Systems Offer IoT Value

8|15|14   |   2:06   |   (0) comments


New efforts to create single-board computers for IoT applications may add the most value when the systems are deployed as controllers for sets of local sensors. They can lower costs and improve security. But we need to look at the range of applications to be sure we have the needed standards for accessing these controllers.
