Soft robots, medical devices, and wearable devices are now common in our daily routines. Researchers at KAIST have created a fluid switch that employs ionic polymer artificial muscles. This switch functions with ultra-low power while generating a force 34 times its own weight. Fluid switches are designed to direct the flow of fluid, guiding it in specific directions to initiate different movements.

KAIST (President Kwang-Hyung Lee) announced on the 4th of January that a research team under Professor IlKwon Oh from the Department of Mechanical Engineering has developed a soft fluidic switch that operates at ultra-low voltage and can be used in narrow spaces.

The iCub3 robot avatar system has been designed to facilitate the embodiment of humanoid robots by human operators, encompassing aspects such as locomotion, manipulation, voice, and facial expressions with comprehensive sensory feedback, including visual, auditory, haptic, weight, and touch modalities.

The iCub3 avatar system consists primarily of the iCub3 humanoid robot, an evolved version of the IIT’s humanoid robot born two decades ago, and innovative wearable technologies named iFeel.

A research team led by Lawrence Berkeley National Laboratory (Berkeley Lab) has developed “supramolecular ink,” a new technology for use in OLED (organic light-emitting diode) displays or other electronic devices. Made of inexpensive, Earth-abundant elements instead of costly scarce metals, supramolecular ink could enable more affordable and environmentally sustainable flat-panel screens and electronic devices.

“By replacing precious metals with Earth-abundant materials, our ink technology could be a game changer for the OLED industry,” said principal investigator Peidong Yang, a faculty senior scientist in Berkeley Lab’s Materials Sciences Division and professor of chemistry and materials science and engineering at UC Berkeley.

“What’s even more exciting is that the technology could also extend its reach to organic printable films for the fabrication of wearable devices as well as luminescent art and sculpture,” he added.

A recent study published in Nature Electronics discusses stretchable graphene–hydrogel interfaces for wearable and implantable bioelectronics.

Stretchable and conductive nanocomposites with mechanically soft, thin and biocompatible features play vital roles in developing wearable skin-like devices, smart soft robots and implantable bioelectronics.

Although several design strategies involving have been reported to overcome the mechanical mismatch between the brittle electrodes and stretchable polymers, it is still challenging to realize monolithic integration of various components with diverse functionalities using the current ultrathin stretchable conductive nanocomposites. This is attributed to the lack of suitable conductive nanomaterial systems compatible with facile patterning strategies.
