Panasonic, Imec Develop Vibration Energy Harvester
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)
Your story inspired a new energy-harvesting design, Nancy! I think both ideas--your heartbeat and the impact of your feet--could work, though. And in fact, they are working, as one company called SolePower has made energy-harvesting insoles, and another called Pavagen has made tiles that harvest energy when you step on them. There are also pacemakers that are harvesting energy from the human heartbeat for power. So your instincts are dead on. :)
Given the developments in energy harvesting solutions, I take it that reliability is not an issue. I would also guess from these developments that using the energy that drives the other devices on the car is not an option here.
Thanks, Chuck. I'm sure I will have more energy harvesting stories in the future! But you're right, sensors on vehicles are a great application of this. It's kind of a no brainer, and I expect we'll see more of this type of thing in the future.
That's a good idea, Nadine. There is actually a lot of research right now to have devices power themselves through vibration or other methods. I've done some stories about harvesters on airplanes that use thermal energy to power sensors...and also energy harvesters on shock absorbers on cars that use vibration. I think there are a lot of applications for this. Maybe our readers can think of others.
Yes, I thought it was clever, too, Rob. I think this is the way forward and a lot of researchers are thinking this way--to use vibrations and other movements or even sounds or heat from vehicle parts to power sensors on the vehicle itself. There is also work to do something similar with thermal energy on airplanes.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
