Today's Tech News: Notable or Not?

https://www.eurekalert.org/news-releases/1093922 "2D PEDOT tethered dopant templated conductive polymer fabrication improves device's function, cost... conducts electricity as well as metals... smartphones, wearable bio-sensors"

https://techxplore.com/news/2022-06-electricity-over-the-air-simultaneous-transmission-5g.html "receives 5G and millimeter-wave power signal... power signal activates device and provides power... transmission mode sends 5G signal same direction... Thus, a device like this can easily communicate and be part of the Internet of Things without needing a separate plug point, unlike most current indoor Internet of Things devices. The device can generate power over a wide span of angles and distances and, thus, does not suffer from the challenges faced by previous wirelessly powered devices" Related: DARPA looks to laser to beam power across the world https://newatlas.com/technology/darpa-laser-beam-power-across-distances/

The new design uses a core made from carbon composite, the same lightweight, strong material used in making airplanes. Because it’s stronger than steel, there’s less risk of lines sagging dangerously. And because it’s so lightweight, it’s possible to use more aluminum around the outside, doubling the amount of electricity flow"
