Glowing Contact Lens Could Prevent A Leading Cause of Blindness

04-23-18

Hundreds of millions of people suffer from diabetes worldwide, putting them at risk for a creeping blindness, or diabetic retinopathy. Existing treatments, though effective, are painful and invasive, involving lasers and injections into the eyeball. Graduate student, Colin Cook working in Professor Yu-Chong Tai’s laboratory has invented a contact lens that when worn during sleep interrupts the process that destroys cells of the retina. He hopes his contact lenses will offer a solution that patients will be more willing to try because the effort involved is minimal, as are the side effects. [Caltech story]

Third Place At TigerLaunch

04-18-18

MedE graduate student, Colin A Cook, has won third place at the 2017-2018 TigerLaunch Finals for his pitch on a phototherapy contact lens he has been developing with his advisor Professor Yu-Chong Tai. TigerLaunch is a national entrepreneurship competition, dedicated to building student founder networks. It is the largest student-run competition of its kind with events in Chicago, NYC, Paris, Seattle, and Princeton.  It had over 300 applicants in 2017 and over $30,000 in prizes.  Colin learned about the competition and was encouraged to apply while taking Professor Ken Pickar's class E/ME 103: Management of Technology.

Professor Tai Elected to National Academy of Inventors

12-13-16

Yu-Chong Tai, Anna L. Rosen Professor of Electrical Engineering and Mechanical Engineering; Executive Officer for Medical Engineering, has been named fellow of the National Academy of Inventors (NAI). He works on miniature biomedical devices including drug pumps, retinal implants, spinal cord implants, and more. He recently developed a device to count white blood cells that requires just a pinprick's worth of blood and processes samples in minutes. Election as an NAI fellow is an honor bestowed upon academic innovators and inventors who have "demonstrated a prolific spirit of innovation in creating or facilitating outstanding inventions and innovations that have made a tangible impact on quality of life, economic development, and the welfare of society."

Progress for Paraplegics

10-25-12

Joel W. Burdick, Richard L. and Dorothy M. Hayman Professor of Mechanical Engineering and Bioengineering, and Yu-Chong Tai, Professor of Electrical Engineering and Mechanical Engineering, are developing new technologies to expand their research which has enabled a paraplegic man to stand and move his legs voluntarily. The team has until now used intelligent guesswork to determine which stimuli might work best. But soon, using a new algorithm developed by Professor Burdick, they will be able to rely on a computer to determine the optimum stimulation levels, based on the patient's response to previous stimuli. This would allow patients to go home after the extensive rehab process with a system that could be continually adjusted by computer. [Caltech Release] [ENGenious Progress Report]

Stimulating Electrode Array Assists Paraplegic Man to Stand and Move Legs Voluntarily

05-20-11

Joel W. Burdick, Professor of Mechanical Engineering and Bioengineering, and colleagues including Yu-Chong Tai, Professor of Electrical Engineering and Mechanical Engineering, have used a stimulating electrode array to assist a paralyzed man to stand, step on a treadmill with assistance, and, over time, to regain voluntary movements of his limbs. Using a combination of experimentation, computational models of the array and spinal cord, and machine-learning algorithms, Professor Burdick and his colleagues are now trying to optimize the stimulation pattern to achieve the best effects, and to improve the design of the electrode array. Further advances in the technology should lead to better control of the stepping and standing processes. [Caltech Press Release]
