‘Terminator’ Vision for Rabbits; Humans are Next

The future has never looked more like a science fiction movie. A single-pixel wireless contact lens display. We present the design, construction and in vivo rabbit testing of a wirelessly powered contact lens display. The display consists of an antenna, a 500 × 500 µm2 silicon power harvesting and radio integrated circuit, metal interconnects, insulation layers and a 750 × 750 µm2 transparent sapphire chip containing a custom-designed micro-light emitting diode with peak emission at 475 nm, all integrated onto a contact lens. The display can be powered wirelessly from ~1 m in free space and ~2 cm in vivo on a rabbit. The display was tested on live, anesthetized rabbits with no observed adverse effect. In order to extend display capabilities, design and fabrication of micro-Fresnel lenses on a contact lens are

presented to move toward a multipixel display that can be worn in the form of a contact lens. Contact lenses with integrated micro-Fresnel lenses were also tested on live rabbits and showed no adverse effect. In a study published in the November issue of the Journal of Micromechanics and Microengineering.  –  Prof. Babak Amir Parviz:    McMorrow Innovation Associate Professor.Bionanotechnology, Self-Assembly, Nanofabrication, MEMS.Prof. Babak received his graduate degrees from the University of Michigan in Ann Arbor. From 2000 to 2001 he was with Nanovation Technologies Inc. as a device designer and a product manager working on integrated photonics. He joined the Department of Chemistry and Chemical Biology at Harvard University as a postdoctoral research fellow in 2001. At Harvard, he was involved in research on developing novel nanofabrication technologies, self-assembled systems, low-cost biosensing, and using organics for electronics and MEMS. He joined the UW Electrical Engineering Department as a faculty member in October 2003. He is currently the Associate Director of the Micro-scale Life Sciences Center at the University of Washington. Babak is a founding member of the American Academy of Nanomedicine; a senior member of the IEEE; and a member of the American Association for Advancement of Science, American Chemical Society, Association for Research in Vision and Ophthalmology, and Sigma Xi.Research Interests: 1.Research at the interface between biology and

electrical engineering (developing tools for the study of biology at the single cell level, functional contact lenses, ultra-low-cost genome sequencing technology, direct conversion of molecular recognition and binding events to electrical signals, using biomolecules for self-assembling engineered structures, hybrid biological/solid-state devices and systems, low-cost biomedical devices, ultra-low cost biodetection, analysis of complex mixtures of molecules, multiplexed sensing). 2.Engineered Self-assembly(design and construction of self-assembled structures and devices in the micro and nano-scales, self-assembly as an engineering concept, self-assembly across the size-scale, self-assembly for heterogeneous system integration, self-packaging, developing self-assembly as a method for mass manufacturing). 3.Nanotechnology(design and fabrication of nano-scale electronic, photonic, and mechanical devices; investigation of novel nano-scale phenomena for device design in the nano-scale, nanoelectrochemistry).4. MEMS (large area and low-cost microfabrication; green microfabrication; biodegradable micro devices; micro devices for human performance augmentation; novel human-machine interfaces).
