Seoul National University of Science and Technology researchers develop 3D-printed carbon nanotube sensors for smart health monitoring
Polymer-based conductive nanocomposites, particularly those incorporating carbon nanotubes, are highly promising for the development of flexible electronics, soft robotics and wearable devices. However, CNTs are difficult to work with as they tend to agglomerate, making it hard to obtain a uniform dispersion. Moreover, conventional methods limit control over CNT distribution and shape.
To overcome these challenges, researchers are turning to additive manufacturing (AM) or 3D printing methods, such as vat photopolymerization (VPP), which offer excellent design freedom with high printing accuracy. In this method, a light is used to selectively cure and harden layers of an ink within a vat, ...
