| Abstract Scope |
In this research, we develop a nature-inspired droplet-based nanoparticle 3D printing method that creates highly complex three-dimensional architected structures and use them to make new device structures. Fluid dynamics of aerosol microdroplets is used to stack nanoparticles (or 2D nanoflakes) in 3D space without auxiliary support to create such structures. We use 3D printing to create fully customizable brain-computer interfaces (BCIs) having recording densities of thousands of electrodes/cm2, which is 5-10x higher than the current state-of-the-art BCI technologies. The technology is tested by recording the action potentials from the mouse brain and rat spinal cords. The same technique is also used to create high-capacity Li-ion batteries and thin flexible robotic skins with embedded sensors. We then demonstrate digital twins of the manufacturing process used to create these structures. |
