Dubbed Thinfilm Addressable Memory, the new device marries Thinfilm’s printed memory technology and PARC’s printed transistors to create an honest-to-Moore CMOS circuit. How? Using organic, ferroelectric polymer ink. The exact process isn’t detailed, but the printed circuit basically looks like a horizontal, rolled-out-flat integrated circuit. In other words, instead of stacking multiple layers of semiconductor to make a transistor, they are laid out next to each other, with different inks forming the various features required to make a memory cell or transistor. It’s no where near as space-efficient, and the number and size of components is obviously limited to the resolution of the printer but by Thor, it actually works, they're very cheap to produce (a few cents), and they're physically very flexible."

"Tentzeris and his team of researchers, including IEEE members Rushi Vyas and Vasileios Lakafosis, have created a self-powered sensor that relies on an ultrawideband antenna to capture energy from the 100 megahertz and greater frequencies generated by all those systems. The scavenged energy is converted from AC to DC, and then stored in a capacitor that gradually fills until the sensor is fully charged. The team has used the antenna to power a number of sensors, including sensors that detect heat and humidity, as well as biosensors that monitor physiological changes in humans. And Tentzeris says that as the technology advances, it has the potential to charge other devices."
