| Abstract Scope |
Flexible circuits have revolutionized health monitoring. Sensors that can detect temperature, glucose, or pH provide valuable real-time data. Contact lenses equipped with these sensors using biocompatible polymers and encapsulated electrical circuits and microcontrollers represent one possible application. The development of smart lenses requires that electrical components must lie outside of the line of sight and without eye irritation, while fabrication techniques must translate circuits to a curved surface. Aerosol jet printing, an additive manufacturing technique, shows promise for this application. Notably, the standoff between the print nozzle and the substrate allows printing over nonplanar surfaces, and the highly collimated beam provides a large depth of focus. Silver particle-free ink and polymethyl methacrylate sheet, representing traditional hard contact lenses, was used for an initial proof-of-concept. Prints were characterized for deposition quality, electrical resistance, trace dimensions, ink densification, and adhesion to the substrate. Results and suggestions for future directions will be discussed. |
