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 operates on the 2.4 GHz frequency. The problem is that this band is very popular: you'll also find Wi-Fi, cordless phones, microwaves, and some...
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...
Our electronic devices — phones, tablets, laptops — emit weak electromagnetic waves. Individually, a single smartphone is not worrying. The concern arises when hundreds of...
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...
