Panasonic, Imec Develop Vibration Energy Harvester
7/23/2013

Panasonic and Belgian company Imec have teamed up to develop an electrostatic energy harvester that can power tire pressure monitoring systems (TPMS) using vibration and noise from the tires themselves. These systems are mandatory in the US for new cars being manufactured and soon will be in Europe.   (Source: Imec)

I would agree with you on this, AandY, and I think energy harvesting is becoming so sophisticated that it will replace batteries someday in a lot of devices. Or at least I hope so!

Thanks for that link, Nancy. Every time I've read one of Liz's articles, I've wondered about using energy harvesting to power a pacemaker or implantable defibrillator. But I never considered that the heart itself would provide the current. Great link.

Thanks, Elizabeth - I had not seen that!

 

Yet another great idea, scooped...

Forgive me if I'm repeating myself, dbell5, but did you see this article I wrote: http://www.designnews.com/author.asp?section_id=1386&doc_id=264515


That's the one about the energy-harvesting shock absorbers. Maybe I posted it already in a comment, if shock absorbers already were mentioned, but I am not sure. In any case, you are right that this seems a great place for energy harvesting.

Since shock absorbers were mentioned, I've long thought that there lies an ideal, essentially free, source of recovered energy. Because the very purpose of them is to convert mechanical energy into another form - generally heat - as a means of damping motion, it seems a no-brainer.

With current power management and conversion devices, controlled transformation of suspension motion into electrical energy is looking feasible.

Tire vibration energy harvester

While I agree that tires are a noisy environment I also question the assertions about "shocks" in the tire rotation. There is a flexing motion but that does not fit the normal descriptio  for a shock wave. In addition I have a concern about the lifespan of anything attached to the tire's inside surface. While it would be a good location for capturing flexural motion it would also be subject to damage from the tire installation and removal operations. But the concept of powering a tire pressure monitor from vehicle motion is a very good idea. The challenge will be the effort of making sure that the receiver on the vehicle is able to communicate with the tires correctly.

That definitely seems to be the direction this technology is heading, Chuck. It doesn't seem to make sense to try to power MCUs any other way now, especially with the deman for ultra-low-power electronics.

Given the power stinginess of some of the new breed of microcontrollers, I would think many MCUs will soon be driven by energy harvesting systems, if they aren't already.

Going by the confidence that Panasonic and Imec are portraying in regard to their new development, it would only be right to assume that the effectiveness of the energy harvested matches the other mainstream sources of energy or even surpasses them. It would be a great disappointment to raise the hopes of car developers before a great backlash.

Speaking of safety lights...I just saw an article yesterday in the Int'l Herald Tribune about new safety lights on bikes.  Click here to read it.

I really like the lasers.  They look cool and make you much more visible!

The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
Researchers have developed a new flexible fabric that integrates both movement and sensors, introducing new potential for technology-embedded clothing and soft robots.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
