This research work proves that there is a big bang future in nano technology. The 20 times boost in piezo response will help in many places like sensors for vibration monitoring,convertion of vibration in to power etc. The thrermo electric device 60to 90% is even though a small development the cost accompanying the milling them may over come the benifit.
Energy harvesting is another one of those technologies that seems to forever be "almost here," which is why I combined these two separate research efforts into a single story. Both piezoelectric and thermoelectric energy harvesters were demonstrated many years ago, but the devil-in-the-details has been efficiency. These two enhancements of their respective coefficients bring both energy harvesting technologies closer to commercialization, but ti looks like the apps are still going to be "almost here" for at least a few more years.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
