Stretchable bioelectronics with silver hydrogel composite

Electrically conductive, flexible hydrogels to open the door for wearable electronics and soft robots


Key points from article :

Researchers developed a silver-hydrogel composite that can conduct electricity.

Include skin mounted electrodes that may be helpful in treating muscular disorders or other motor issues.

Soft materials are expanding the possibilities for biomedical devices that can safely and delicately interact with human tissues.

“This new composite can have many applications in bioelectronics and beyond,” - Carmel Majidi, co-researcher.

“Examples include a sticker for the brain that has sensors for signal processing, a wearable energy generation device to power electronics, and stretchable displays.”

Created by suspending tiny silver flakes in a polyacrylamide-alginate hydrogel.

By hydrating or dehydrating the gel, electrical connections can be turned on or off.

To print electrodes that can be attached to skin to stimulate the muscles beneath.

Demonstrated its potential in creating soft robots by creating a soft stingray robot that can swim.
