Researchers have developed a battery-free sensor that reacts to sound waves, such as particular spoken words, producing enough vibrational energy to power an electronic device. The novel sensor would ...

Do tire pressure sensors use individual batteries (that may last only 10 years) rather than the car’s electrical system? Could such a battery replacement cost about $85 for each wheel? Let me guess, ...

Scientists have created a new type of chemosensor (demonstrated for lactic acid sensing) which functions with electricity but without the need for reference electrodes or battery power. Scientists at ...

The $50 sensor runs on two coin cell batteries so you don’t need a nearby power source for installation. The $50 sensor runs on two coin cell batteries so you don’t need a nearby power source for ...

Have you ever worried about your phone or car battery overheating? With lithium-ion batteries powering everything from smartphones to electric vehicles, safety has become a significant concern for us ...

The battery packs in electric vehicles (EVs) are only as safe and effective as the battery-management system (BMS) watching over it. The BMS plays a pivotal role in the EV, monitoring the voltages in ...
