According to the British "New Scientist," recently reported that American scientists will be eye-friendly transparent materials combined with microelectronics, developed a new type of contact lenses, the glasses can monitor blood glucose concentration in diabetic wearers. Previously, researchers also developed smart glasses that could detect whether the wearer had signs of glaucoma. Smart contact lenses have become a healthy "guardian angel."
Intelligent contact lenses monitor glucose levels In 2008, Barbaker Pavez, an associate professor of electrical engineering at the University of Washington, created a contact lens model that contains a red light-emitting diode (LED). He now uses the same technology to create contact lenses that monitor the body's glucose concentration.
Paviz said that he designed the glucose sensor to use an electrode to allow micro currents to flow through the tear fluid and measure the current to detect the concentration of glucose in the tear fluid. The glucose concentration in the tear fluid can directly reflect the concentration of glucose in the blood. Therefore, the new sensor can monitor the blood glucose concentration of the wearer and send related information to the portable device worn by the diabetic. The doctor can manage the patient's diet and medication more precisely.
These electrodes, along with a computer chip containing a radio frequency modulated antenna, were built on a flat substrate made of polyester synthetic fibers. Pavez then molded all these substances into the shape of a contact lens.
Basic tests show that even with very low glucose concentrations, this new sensor can be accurately detected. Pavizi plans to publish its latest findings at the Institute of Electrical and Electronics Engineers 2011 MEMS Conference held in Cancun, Mexico this month.
Contact lenses improve the therapeutic effect of glaucoma. In September last year, Sensimed, affiliated with the Swiss Federal Institute of Technology, released the world's first commercially available smart contact lens designed to improve the therapeutic effect of glaucoma patients.
Glaucoma is an eye disease that can lead to blindness. Although it cannot be completely cured, patients can still control their condition if they can perform regular IOP test to diagnose and correct treatment in time. The current test method can not fully detect the change of the intraocular pressure of the patient. It is often diagnosed after the optic nerve is damaged to a considerable degree, and it becomes a blind spot for treatment.
Jane-Marc Wismo, CEO of Sensimed, said that the company's launch of the Triggerfish contact lens has a miniature pressure sensor embedded in it that can record changes in corneal pressure and eyeball pressure over a period of time (usually 24 hours). The curvature of the eyeball can be periodically transmitted wirelessly to a small receiver on the patient's neck. The receiver can then transmit the information to the computer via Bluetooth technology. The accuracy of the information obtained through this contact lens lens is beyond the reach of traditional ophthalmic instrument testing. Doctors can diagnose early and formulate the best treatment plan based on the patient's condition. This product has first been sold at a designated European medical center and is being tested on a large scale. In 2011, it will be put into the US medical market.
Smart contact lenses or augmented reality can be realized. In addition, these contact lenses developed by Paviz can also directly display pictures in the line of sight, and finally experience augmented reality for the wearer (also known as mixed reality, referring to computer technology. The virtual information is applied to the real world, so that the real environment and virtual objects are superimposed on the same scene or space in real time.) A head-up display effect is created.
Contact lenses, including arrays of small light emitting diodes (LEDs), also allow various digital information to be displayed directly to the wearer through the glasses. At present, this kind of augmented reality has been implemented on mobile phones. Numerous software applications have placed digital information on top of pictures displaying our surrounding information, allowing the physical world and the online world to effectively blend together. However, it is not easy to achieve this on contact lenses, but Pavizi's sensors are basically done.
Pavez said: "We still need to conduct more tests." Now, its laboratory has made progress in the contact lens display, they have developed a red and blue micro LED, only the green is complete Eyeglasses with three-dimensional optics have also been produced, the appearance of which is similar to that used to watch three-dimensional movies. Pavizi intends to combine optics and LEDs in the same contact lens. He said that the LEDs will be grouped into a grid pattern that will not interfere with normal vision when the display is turned off.
All of these glasses need to solve a problem - wearing this kind of glasses may make people look like the robot in the film Terminator. Pavez said that a fake pupil may solve this problem.
