Soft robotics and ion printing


 

Electrically-charged hydrogel has applications for soft robotics and biomedical fields

The “ionoprinting” technique, as the team has dubbed it, uses a copper electrode to inject positively-charged copper ions into a hydrogel material (a highly absorbent polymer material that is nearly 99.9 percent water). The copper ions bond with negatively charged ions n the hydrogel’s polymer network, creating a more robust and mechanically stiffer structure.

Applying an electrical current then causes the hydrogel to flex. Although electrical fields have been used to actuate hydrogel materials before, this is the first time that electromechanically active electrodes have been used to drive the motion. Also, this is the first time that the binding of ions has been used to create a more rigid hydrogel network in this way.


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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
