«This study can be used to diagnose diseases (diabetes and glaucoma) by implementing two types of transparent electronic sensors in the production of smart
contact lens sensors,» said Professor Park.
In addition, because the system uses wireless antenna to read sensor information, no separate power source, like battery is required for the smart
contact lens sensors.
«It was observed that the live rabbit did not show any abnormal behavior when wearing
the contact lens sensor,» says Joohee Kim (Combined M.S. / Ph.D. student of Materials Science and Engineering), the first author of the study.
«Smart
contact lens sensor» for diabetic and glaucoma diagnosis.»
In the study, the research team unveiled a smart
contact lens sensor that could help monitor biomarkers for intraocular pressure (IOP), diabetes mellitus, and other health conditions.

Yes, a
contact lens made with super-tiny chips and
sensors and an antenna inside that — of course — you wear right on your eyeball.
Such flexible, biofriendly and transparent energy sources could someday energize implanted health
sensors, insulin pumps or high - tech
contact lenses that project virtual displays onto the wearer's line of sight.
The powered antenna transmits electricity to the
contact lens, which is used to interrogate the
sensors, process the signals and transmit the readings back.
Furthermore, since the electronic
sensor is inserted into the soft
contact lens, the feeling of wearing it is also excellent.
According to the research team, their newly - developed smart
lenses with built - in pressure - sensing and glucose - monitoring
sensors could still detect blood glucose and IOP despite the deformation of the
contact lenses.
«It should be noted that glucose is present not only in the blood but also in tears, and thus accurate monitoring of the glucose level in human tears by employing a
contact -
lens - type
sensor can be an alternative approach for noninvasive glucose monitoring,» the researchers wrote.
The miniature solar panels could power myriad personal devices — wearable medical
sensors, smartwatches, even autofocusing
contact lenses.
These include electronic - skin coatings that can detect blood oxygen levels,
contact lenses made from metal - oxide thin films that can detect glucose levels in tears and flexible integrated
sensor arrays based on plastic and silicon integrated circuits that can detect molecules like glucose in sweat.
The previously - revealed information about the
contacts, which included miniature
sensors, processors, and other electronic bits within the
lens was focused on its ability to detect glucose levels.
The technology is simply a tiny wireless chip and
sensor wedged between two pieces of normal
contact lens material.
In fact, Google owns two patents already for such «smart
contact lenses» having
sensors and flexible electronics, which read the proportion of chemical in the eyes of the wearer to determine their blood sugar levels.
Its latest Google X project can measure glucose levels in diabetics thanks to tiny
sensors that are sandwiched inside of a clear
contact lens.
As is outlined in the resulting research paper, which is titled «Soft, smart
contact lenses with integrations of wireless circuits, glucose
sensors, and displays,» the researchers were able to create a
contact lens which could respond to changes in glucose and provide results via an LED panel on the
lens itself.
Researchers at Google are working on a
contact lens that alerts diabetics to changes in their blood sugar levels and adjusts the required doses of insulin accordingly,
sensors can detect the onset of a user's epileptic seizure, and the independently controlled robotic walking device launched last year by Rex Bionics could one day change the lives of wheelchair users.
