Ongoing smart contact lens research ranges from biosignal detection (intraocular pressure, glucose, cortisol) to therapeutic tools (aniridia, chronic ocular inflammation) and advanced features such as aumented reality displays and personalized designs using 3D-printing technology. Some of these technologies are already finding their way from the lab into commercial applications. The development of next-generation, smart contact lens technology is not just simply one field of bioelectronics but rather a complex, interdisciplinary effort that includes development of biocompatible materials; development of intuitive interfaces; and development of integration technologies capable of smart contact lens research.
The three-dimensional (3D) geometry of 3D-printed nanopixels can increase the emission brightness of display pixels, varying with the height of the pixels, and can be used to fabricate super high-resolution devices. 3D printing of perovskite nanopillars can be used for creating nanoscale display pixels as well and the increase of the emission intensity can be saturated by the limited depth of field of the measuring optical system.
Liquid crystal materials are ubiquitous in everyday life. Recently, a new way to create advanced liquid crystal materials by merging nanotechnology and liquid crystals was discovered: by adding nanoscale objects to liquid crystals, new materials with superior physical properties can be created. However, this raises an important question: How do nanoparticles affect ionic processes in liquid crystals? Here is an overview of recent advances in the understanding of ionic phenomena in liquid crystals doped with nanomaterials.
