Researchers from Oregon State University (OSU) are studying a transparent sensor on a contact lens that would allow type 1 diabetes patients to monitor their blood glucose levels and possibly even control their insulin infusions.
The sensor reportedly uses a nanostructured transistor that can detect subtle glucose changes in physiological buffer solutions, such eye tear fluid. Additionally, the sensors would be able to transmit real-time glucose information to a wearable insulin and glucagon pump to deliver the hormones as needed.
According to researchers, they have fully transparent sensors that are working, and their next step is to fully develop the communication aspect of the device.
