Anagear's Low-Power Circuits Harvest & Save Energy
Anagear’s ultra-low-power circuits are aimed at separating power management in low-power devices from the microcontroller in order to reduce the need for battery power and make way for alternative energy sources, such as solar power. (Source: Anagear)
Not if meets the right balance of cost and performance. If it adds too much cost to the BOM then only the designs trying to squeeze every last nanowatt will want the part. On the other hand, if they get the part under a dime in volume then I can use a cheaper, power guzzling micro and spend the dime on their part. It's another performance/cost trade off.
It definitely seems like Anagear is on to something here with its preservation of power it manages by taking power management out of the microcontroller. It seems a fairly simplistic idea and will be interesting to see if this takes off. I wonder if designers might balk at making this change to the time-worn design.
Very true, so many designs simply need to wake up every second or so to make a measurement and that clock circuitry usually takes a few microamps. Microcontroller vendors have gotten better at providing a low current wake-up but aren't really there yet.
ZiLOG has a pretty nice watchdog circuit in their Encore parts that can do it with less than a microamp.
For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
Green energy is being billed as a way to make communities that are energy deprived more self-sustaining. So it makes sense to use natural materials to create devices that harvest this type of energy. That’s the idea behind a hybrid wind/solar energy harvester made of bamboo that’s been developed by UVM researchers.
Anyone who’s ever moved files from a hard drive to a computer has sat patiently waiting for the transfer to complete. But what if this process could be done wirelessly, without having to connect devices with cables, and in seconds?
