Retinal prosthesis

Artificial Sight is an attempt to partially restore vision by electrically stimulating retinal cells in order to counteract the effects of illness caused by photoreceptor dysfunction, such as pigmentary degeneration of retina (retinitis pigmentosa) and age-related macular degeneration (AMD). The ultimate goal of this course is the development of a CMOS-based retinal chip.

Implanted sensors in mouse brain

As part of our research into the brain’s mechanisms of memory and learning, we are studying devices that can be implanted into the brains of living mice in order to study brain-imaging interactions. With these implanted chips, we can apply stimuli and obtain highly sensitive measurements of internal events -- experimental techniques that were impossible with conventional methods.


We look forward to further advances in our micro-Total Analysis System (μTAS), which is based on a chip capable of performing chemical analysis. The μTAS chip combines fluid channels, valves, sensors and other fluid and mechanical components on a glass substrate several mm square, and is capable of providing fast, highly efficient and inexpensive chemical analysis. Our laboratory is working to incorporate additional sensing capabilities from CMOS technology and signal processing into these chips.
