Smart Contact Lenses

Soon, Smart Contact Lenses Can Measure Blood Sugar Level of Diabetes Patients.

Smart Contact lenses filled with transparent sensors can help one day to monitor blood sugar levels of people with diabetes,

They would give people a way to control their blood sugar levels without bleeding their blood, according to scientists who are developing on the ice lenses.

Typically, people with diabetes took blood from their finger with a tiny needle to measure blood sugar levels. This could be painful for patients; some patients had to rinse this procedure several times a day.

Gregory Herman, a chemical engineer from Oregon State University, said the recommended smart contact lenses could continuously monitor a person’s blood glucose levels during the day. Herman, such continuous monitoring, can help reduce the risk of diabetes-related health problems; Herman said he was reporting significant changes in his blood sugar level. (In a person with diabetes, the body cannot reach the person’s cells with blood from shape or glucose. Blood glucose can cause medical problems.)

There are devices that continuously monitor blood sugar levels, only the electrodes that are often painful, which may cause skin irritation or infections, need to be placed under the skin and need to be replaced every few days. Herman said that smart contact lenses, which can monitor continuous and non-invasive blood sugar levels, can eliminate many of these problems. Where smart contact lenses are invisible, people can use themselves without feeling conscious.

From Electronics to Eyes:

Researchers used the technology developed for electronic products to make contact lenses for blood sugar monitoring. Researchers have recently softened their electronic features with a material called indium gallium zinc oxide (IGZO), which has helped improve the image standard on Smartphone’s, tablets and flat panel displays, while also saving power and improving touch screen sensitivity.

If you buy an iPhone or Apple computer or flat-screen TV today, they use IGZO, In the study, researchers made smart contact lenses containing transparent layers of transistors made with IGZO. Transistors were coated with an enzyme called glucose oxidize, which breaks down sugar, to control that the lenses can measure glucose levels. This meant that when the smart contact lenses were exposed to glucose, a chemical reaction occurred with the enzyme breaking down the sugar. The transistors measured this reaction, indicating that glucose was present, through changes in the electric currents flowing through the lenses.

Researchers have found that sensors can even detect glucose at very low concentrations, such as levels typically found in tears.

Herman theoretically stated that 2,500 of these sensors could be placed in the 1-square-millimeter patch of the contact lens. The official said that using Wi-Fi or Bluetooth, the data collected by the lenses can be transferred wirelessly to Smartphone’s or other devices. Best Technology That Will Turn Your Life.

Blood sugar:

Herman said the potential use of biosensor smart contact lenses does not measure blood sugar levels. Researchers can be used to help monitor a range of other conditions, such as lenses cancer, AIDS, glaucoma, and kidney or liver disease.

For example, sensors may be developed to measure chemicals called uric acid, which are found at higher levels in kidney disease or gout patients. In addition, the lactate-measuring sensors can help monitor liver disease or sepsis; and the neurotransmitter dopamine’s sensors can help monitor glaucoma.

You can also look for HIV or cancer-dependent molecules, “said Herman. I want to see if there are good ways to catch cancer in the early stages rather than a fatal disease. “

Herman said the lenses are still in the very early stages of development. The prototype biosensor said the contact lens could take a year or more without being ready for the animal test and the tests in humans are further away.
