Researchers at NC State have developed a way to print liquid metals into 3D structures at room temperature. The structures are stabilized by a thin oxide ‘skin’ that forms on the liquid metal. The approaches shown here represent new ways to direct write metals in 3D. In addition, the resulting components can, in principle, self-heal ( “Self-healing stretchable wires” ) and be ultra-stretchable ( “Ultra-stretchable wires” ).
The paper, “3D Printing of Free Standing Liquid Metal Microstructures,” is published online in Advanced Materials….
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
