IBM aannounced a materials science breakthrough at the atomic level that could pave the way for a new class of non-volatile memory and logic chips that would use less power than today’s silicon based devices. Rather than using conventional electrical means that operate today’s semiconducting devices, IBM’s scientists discovered a new way to operate chips using tiny ionic currents, which are streams of charged atoms that could mimic the event-driven way in which the human brain operates.
Optical image of a typical ionic liquid (IL) gated device with a droplet of IL on top of the gate electrode and the oxide channel. The gold squares are pads used to make contact to the device via wire-bonding. On right is the magnified image of the device showing the channel (brownish yellow) and the gold electrical contacts (bright yellow). The contacts on the right and left of the channel are the source and drain contacts. The four other contact are used for 4-wire resistance & Hall measurements. (Credit: IBM)

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
