Supercapacitor

We have all seen old rubber band wind-up planes built by crazy makers. Tom Stanton, a youtuber, just turned one into a 21st century electric wind-up plane powered by a supercapacitor. He is an engineer and a maker who loves to mix physics, 3D printing and clean energy storage. Instead of winding up a rubber band, he used his hand crank generator to charge a supercapacitor. This stored energy…

During the late 1990s and early 2000s, BEAM bots gained immense popularity among hobbyists and tinkerers, captivating the DIY robotics community with their simplicity and ingenuity. These minimalist robots, named for their foundation in Biology, Electronics, Aesthetics, and Mechanics, became a staple in robotics clubs and maker fairs, celebrated for their ability to mimic natural behaviours…

Smart home technology is continuously evolving, with energy efficiency driving innovation. A standout project in the developer community is the Battery-Less Smart Door Sensor, a highly efficient system that runs entirely without batteries. Powered by solar energy and supercapacitors, this breakthrough device eliminates the need for traditional batteries, making it a sustainable option for…

Maker Jamie Matthews has recently created a new supercapacitor-powered speaker that significantly enhances charging speed and playtime duration. This speaker charges remarkably fast, achieving a full charge within seconds, and offers a minimum of six hours of continuous playtime without the need for solar power. This efficiency is credited to the use of a TPA2013D1…

South Korean teams led by Jang-Ung Park at Yonsei University in Seoul and Sang-Young Lee at the Ulsan Institute of Science and Technology in Ulsan have come up with smart wirelessly charging contact lenses. The soft and wirelessly recharging smart contact lens can be used to track the wearer’s health without compromising on comfort. The contact lens could continuously…

There is a long debate that Supercapacitors will overrule the battery market in the future. A few years back when Supercapacitors were made available, there was a huge hype about it and many expected it to replace the batteries in commercial electronic products and even in Electric Vehicles.  But, nothing like that actually happened, because both Supercapacitors and…

Flashlight or Torch is very useful in emergency situations like power failure. These flashlights are battery-operated, and we have to charge regularly in particular intervals. But what if you don’t have electricity and your flashlight is dead? In that situation, Mechanical chargeable Flashlights is very good option, which can be charge by rotating the lever attached to it.…

The term Supercapacitors and its possible usage in Electric Vehicles, Smartphone’s and IoT devices are being considered extensively in the recent times, but the idea of super capacitor itself dates back to 1957 when it was first experimented by General Electric to increase the storage capacity of its capacitors. Over the years Super capacitor technology has improved…

The power electronics industry has been on an upward spiral and shows no signs of abating, as the trend of electrification penetrates a wider range of industrial domains and entails the requirement of high-tech power electronic devices. In recent years, there has been a marked rise in the need for advanced electricity storage solutions, triggered by the essentiality of…

The capacitor is a two-terminal passive component, which is widely used in electronics. Almost, every circuit we find in electronics, use one or more capacitors for various usage. Capacitors are the most used electronics component after resistors. They have a special ability to store energy. There are different types of capacitors available in the market, but one which is…
