Scientists 3D-print biomedical devices in study that may ‘open up new possibilities’

Researchers say highly conductive printing ink can be used to create circuits in jelly-like hydrogel. It can then be used for devices to monitor heart rate and stimulate nerves, according to the team. — SCMP

A Chinese-led team of scientists say they have developed a highly conductive 3D printing ink that can build circuits in hydrogel to create devices that can be used to monitor heart rate and stimulate nerves.

Radio-frequency identification (RFID) chips – used in credit cards and as pet microchips – could also be added to the jelly-like hydrogel to store information like medical records, according to the researchers.
