Since Google launched smart glasses, smart glasses have been the focus of major technology giants. Compared with smart watch or smart Bracelet wearable devices, smart glasses have a broader application space and prospects. Therefore, smart glasses have always been the focus in the field of wearable devices, and it is also a main research field of major technology giants and related scientific research institutions.
According to foreign media reports, an experimental Sunglasses developed by a team led by Suk wonhwang, associate professor of ku-kist Graduate School of integrated science and technology, Korea University, has come out.
The sunglasses can not only monitor the health of users, but also allow users to control the game and convert it into Sunglasses according to their own needs. The current prototype of the “electronic glasses” has been completed with 3D printing technology, with flexible electrodes implanted near the wearer’s ears and eyes. The sensor of the former is equivalent to electroencephalogram (EEG), which is used to monitor brain activity with the help of EEG technology, while the function of the latter is equivalent to electrooculogram (EOG), which is used to track eye movement. These two kinds of data are processed through the wireless transmission of glasses.
In laboratory tests, EEG successfully recorded the alpha rhythm of volunteers. The so-called alpha rhythm refers to human brain waves. At present, human brain waves are divided into four categories (alpha wave, alpha wave, Q wave and delta wave) in medicine, one of which is alpha wave.
When we go to the hospital to do electroencephalogram, the doctor first attaches electrodes to your head, and then asks you to close your eyes and try to “use no brain”. At this time, the recorded brain wave is alpha wave (8-13 Hz), which is called “alpha rhythm” in the West. This kind of smart glasses is to monitor our health by monitoring “alpha rhythm”.
In addition, the researchers added an acceleration sensor to the same leg to track the user’s posture and gait. The sensor can detect the required information when they fall. This means that this kind of glasses can be used for home care of the elderly, and can automatically send an alarm once a fall accident is found.
In addition, an ultraviolet sensor is installed on one leg of the electronic glasses, which can be used to measure the intensity of incident ultraviolet light. When the sunlight is bright enough, the sensor will trigger the UV Gel inside the lens to darken the lens and turn the glasses into sunglasses for the time being. The continuous maturity and improvement of industry chain technology and the continuous miniaturization of electronic components will inevitably lead to the explosive development of intelligent glasses industry.
