BBC has a story on a new self-healing plastic that functions similarly to human blood-clotting. The development sounds like it could lead to new levels of DIY repair.
A new plastic that “heals itself” has been designed, meaning your cracked phone screen or broken tennis racquet could mend its own wounds.
The polymer automatically patches holes 3cm wide, 100 times bigger than before.
Inspired by the human blood clotting system, it contains a network of capillaries that deliver healing chemicals to damaged areas.
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.
