When the cable is bent, especially near the ends, the stresses concentrate intensely in the same spot. This concentration of stresses leads to repeated mechanical...
In cold weather, the lithium-ion batteries in our devices struggle to deliver their usual performance. Why? Because the cold slows down the chemical reactions inside...
Our wireless headphones often use a Bluetooth connection in the 2.4 GHz band, shared by many other common household devices: Wi-Fi routers, cordless phones, smartphones, baby monitors,...
Bluetooth uses radio frequencies to allow wireless communication between devices. More specifically, Bluetooth uses the 2.4 GHz frequency band, which is an open and unlicensed...
Our smartphones use lithium-ion batteries, in which chemical reactions allow for the storage and release of energy. When it’s hot, these chemical reactions become faster...
The blockchain is made up of many independent computers distributed all around the world, without a central authority or single leader. Each computer (or node)...
Our electronic devices heavily depend on a stable electrical voltage, which is somewhat like the fuel for internal circuits. An insufficient voltage level can cause...
Electronic devices such as mobile phones, tablets, and laptops emit electromagnetic signals when turned on. These signals can potentially create interference with aircraft navigation instruments. The electromagnetic...
A USB key can malfunction when its internal components take a hit or wear out prematurely. You may not necessarily see it, but the internal...
Our wireless headphones use radio waves to communicate. The thing is, they are not the only ones doing it: Wi-Fi, mobile phones, and even some...
