In the future, your contacts lenses may do more than help you see clearly — they may help save your life.
Engineers at Oregon State University are working to embed transparent sensors into contact lenses, which could then monitor biomarkers to track drug use, blood glucose levels, or even detect early signs of cancer.
“My group had been working on a different technology for glucose sensing … which is similar to what is used for glucose test strips,” Greg Herman, a chemical engineer who is leading the research, told Digital Trends. “On a separate project, we were working on transistors that can be transparent. It came to me that we could modify the transistor to be a sensor and make it fully transparent.” The step from conception to creation came quickly, he added.
