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.
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.
