  MyZone has announced a fitness tracker for your chest, arm and wrist MZ-Switch, the company says: it is the first device in the world that monitors PPG (photosynthesis chart) and ECG (electrocardiogram) readings to monitor activity more accurately with fewer blind spots. The key point here is how the accuracy of wrist-based heart rate monitors (i.e. most wearables) can be affected when holding an object, affecting blood flow in a way that is not related to your effort. MyZone says: the wrist-based MZ-Switch should remain 95 percent accurate for any activity that is not restricted by repetitive movements, such as swimming, and typical activities, such as: running and high-intensity stretching. Tracking technology Tracking technology is standard, using an optical flow sensor that illuminates an LED light in the skin to measure the movement of blood in the arm. This flow matches the heartbeat that pumps blood throughout the body to determine the user's heart rate. For exercises that...

 Apple has entered into a partnership agreement with Taiwan Semiconductor Manufacturing Co.(TSMC) to develop ultra-advanced micro OLED displays at a secret facility in Taiwan, according to Nikkei. Small OLED displays will be used in (upcoming augmented reality devices). Micro OLED screens are developed directly on the chips instead of the glass substrate, resulting in thinner, smaller and less energy-consuming screens. These smaller, slimmer OLED displays are ideal for smaller devices such as the smart glasses that Apple is rumored to be working on. The development process of small OLED screens is in the stage of pilot production Rumor has it that the development of small OLED screens is in beta production, and it could be several years before Apple and TSMC are ready to start large production, making these screens suitable for Apple Glasses that are expected to be launched sometime in the year 2023. The screens are said to be less than an inch in size, and this is where Apple will...

Other phone manufacturers began to crave this screen: OnePlus, Oppo, Samsung and Xiaomi, and soon the feature was included with their flagship phones. In fact, you can now ask what companies have not used the feature of high refresh rates in their phones so far, and you will find that LG was one of those one step behind. But, if you're looking for a high refresh rate feature in your next phone, you should know a very important set of points, which we'll review with you today in this article. In 2020, we are starting to see high refresh rates in the screens of middle-class phones as well, which cost only 3 300$ . And you will not find one or two phones, but Realme, Oppo, Xiaomi and OnePlus will find phones with...
