“For the Rundbuntplasma I wanted that the main power supply (a big 20A/5V supply) could be hard disconnected (aka operating the main power switch in our hacker space) from mains and the Raspberry will still shutdown nicely automatically. The …
“Printed electronics and organic light-emitting devices now perform at levels sufficient for a number of eco-friendly, energy-efficient applications. Previously the idea has been to drive the organic electronics using solar cells, batteries or wireless transformers, which works well in many …
“A team of UCF scientists has developed a new process for creating flexible supercapacitors that can store more energy and be recharged more than 30,000 times without degrading. The novel method from the University of Central Florida’s NanoScience …
“Take some metal scraps from the junkyard; put them in a glass jar with a common household chemical; and, voilà, you have a high-performance battery. ‘Imagine that the tons of metal waste discarded every year could be used to provide …
“Energy storage devices called supercapacitors have become a hot area of research, in part because they can be charged rapidly and deliver intense bursts of power. However, all supercapacitors currently use components made of carbon, which require high temperatures and …
“In this project I will show you how I created a very popular and easy to build circuit, the joule thief, in order to power LEDs with voltages from 0.5V to 2.5V. This way less power from the …
“Lawrence Livermore National Laboratory (LLNL) researchers, along with a team from UC Santa Cruz (UCSC), have devised a method for doubling the performance of 3-D-printed graphene-based supercapacitors. The method, which involves sandwiching lithium ion and perchlorate ion between layers of …
“Zero-power autonomous devices will abound on the IoT of the future, and battery manufacturers are scratching their heads to come up with the best possible solution ensuring high energy and power density at miniature scale. A new material developed recently …
News Novel energy inside a microcircuit chip: VTT developed an efficient nanomaterial-based integrated energy storage
“VTT Technical Research Centre of Finland developed an extremely efficient small-size energy storage, a micro-supercapacitor, which can be integrated directly inside a silicon microcircuit chip. The high energy and power density of the miniaturized energy storage relies on the new …
“The goal of this project is to demonstrate IDTs wireless charging technology and the use of supercapacitors as an alternative to battery backups. The device also uses an XBee wireless module to communicate with another identical device with each sending …
