Apple, Garmin, Samsung, Google or Amazfit? I compared each one against a chest strap for heart rate accuracy and found a ...

NASA’s pre-launch preparations for the Artemis 2 mission are off to a rocky start, conjuring memories of the technical issues that delayed Artemis 1 by several months. A redo fueling test this week ...

Researchers at the University of Oxford have developed a powerful new method to visualize an essential lithium-ion battery electrode component that had been extremely difficult to trace before. The ...

Scientists can now see a hidden battery ingredient — and it could supercharge how fast and how long lithium-ion batteries ...

At the time, Motorola were also intent on 'fixing' the "mechanical mismatch between humans and electronics" with a password ...

The open Battery Data Format standard for battery testing data enables researchers, designers, and manufacturers, as well as ...

Reverse polarity is one of the most common causes of circuit failure, from hobby projects to industrial systems. The good news is that a well-designed reverse polarity protection using MOSFET ...

"This project is not about powerful hardware or complex graphics." ...

Abstract: This study focuses on battery degradation within Lithium-polymer (Li-po) batteries. Two factors that can influence the speed of battery degradation are temperature and charging/discharging ...

Solid-state batteries could store more energy and charge faster than today’s batteries, but they tend to crack and fail over time. Stanford researchers found that a nanoscale silver treatment can ...

Abstract: This paper presents about the Smart Battery Management System (BMS) using Arduino controller and NodeMCU. The battery management system is designed to monitor the parameter of battery ...
