By Elizabeth Montalbano – Deriving energy from the heat electronic devices emit so they can provide their own sustainable sources of power is a Holy Grail for scientists developing power sources for sensors that will drive the future of healthcare devices as well as the Internet of Things.
Researchers in Japan now have come up with a new thermoelectric generator that can convert temperature differences to electricity can be used to power small, flexible devices.
Scientists at Osaka University developed the device in the form of a bismuth telluride semiconductor on a thin, polymer film that weighs less than a paperclip and smaller than the size of an adult fingernail.
However, packed in the tiny device is a maximum output power density of 185 milliwatts per square centimeter, which “meets standard specifications for portable and wearable sensors,” Tohru Sugahara, an associate professor at the university’s Institute of Scientific and Industrial Research, in a press statement. more>
ITU News – A handful of old mobile phones – different makes and models, all different sizes and colors – lay in a grey bucket. They are about to be chopped into thousands of unrecognizable pieces.
By Jim Brown – How can manufacturers use the digital twin and industrial IoT to dramatically improve manufacturing and product performance?
By Arthur Pini – The eye diagram is a general-purpose tool for analyzing serial digital signals. It shows the effects of vertical noise, horizontal jitter, duty cycle distortion, inter-symbol interference, and crosstalk, all of which can close the “eye.” While engineers have used eye diagrams for decades, oscilloscopes continually get new features that increase its value.
By Maria M – The foundation of smart manufacturing is an integrated platform that unites the domains required to engineer, manufacture and deliver today’s smart products. Smart manufacturing is a digitalized development strategy that is particularly critical for the electronics industry. Today it’s considered a must have and no longer touted as state of the art or nice to have, cost prohibitive, functionality.
By Maurizio Di Paolo Emilio – A satellite needs an energy source to provide perfect performance, with the battery inside it working continuously for many years. The electrical power system is, perhaps, the most fundamental requirement for the satellite payload, as power system failure results in the loss of the space mission. It’s interesting to note that many of the early satellite systems failed due to these power system failures.

By John Toon – Side channel signals and bolts of lightning from distant storms could one day help prevent hackers from sabotaging electric power substations and other critical infrastructure, a new study suggests.
