From Academia: 3D Printing Contact Lenses, Optics, and Visualization

In this issue of “From Academia“, we include four recent research publications related to “seeing”, including articles focusing on creating smart contact lenses, cornea, glass optics, and microscope leveraging 3D printing technologies. In the first article, researchers presented a way to develop hydrogel-based contact lenses that can have biosensing capabilities, including sensing eye blinking (peristaltic pressure), PH, and Na+ level, adding another tool to the future wearable market. In the second article, researchers demonstrated how additive manufacturing of gradient index (GRIN) silica-titania glass via direct ink writing method could potentially create a variety of conventional and unconventional optical functions in a flat glass component with no surface curvature. In the third article, the researchers described a way to create a 3D corneal stroma using an orthogonally oriented pure electro-compacted collagen (EC). The researchers believe this technique could potentially be used to create a future full-thickness corneal replacement. In the final article, the authors presented UC2 (You. See. Too.), a low-cost, 3D-printed, open-source, modular microscopy toolbox. The authors demonstrate its versatility by realizing a complete microscope development cycle from concept to experimental phase and developing an open standard in optics to facilitate interfacing with various complementary platforms. 

From Academia” features recent, relevant, close to commercialization academic publications. Subjects include but not limited to healthcare 3D printing, 3D bioprinting, and related emerging technologies.
