Comments Off on Bio-friendly energy storage device draws electrical power from the human body

Humans are constantly on the go, so doesn’t it make sense to harness some of that kinetic energy ? Scientists from UCLA and the University of Connecticut asked themselves that question, which eventually led to them developing an energy-storing device that can draw electrical power from the human body. The biological supercapacitor is a protein-based battery-like device capable of extracting energy from the human body. A supercapacitor is a term used to describe a high-performance electrochemical capacitor (ECs), which is similar to batteries but has a much higher power density. Supercapacitors have faster char-discharge rates, lower internal resistance, higher power density and better cycling ability than batteries. Once energy is obtained by the newly-developed energy storage device, it is then released inside an electrical circuit which looks similar to an implantable medical device. According to the paper Ultrathin Graphene – Protein Supercapacitors for Miniaturized Bioelectronics , which was published earlier this month, the supercapacitor utilizes a “harvester” that operates by using the body’s heat and movements to capture electrical charges from ions, which are found in human body fluids including blood and urine. Bleeping Computer reports , “As electrodes, the harvester uses a carbon nanomaterial called graphene, layered with modified human proteins. The electrodes collect energy from the human body , relay it to the harvester, which then stores it for later use.” Graphene sheets can be drawn as thin as a few atoms, which means the incredibly thin supercapacitors could potentially serve as alternatives to batteries. Related: Researchers close in on world’s first 100% self-charging lithium-ion battery Most importantly, the supercapacitors are bio-friendly , as they are made with natural materials. Graphene is composed of carbon, whereas current implantable medical devices are powered by classic batteries that contain toxic materials. Because the new device is thinner than a human hair, it is more flexible than traditional batteries, as well. This technology could have far-reaching implications for the medical industry. Researchers believe that an implantable medical device using a supercapacitor could last a lifetime. In result, patients wouldn’t need to go through operations at regular intervals to replace batteries – one of the main complications with implantable medical devices. In addition to being used with pacemakers, the new energy device could be paired with devices that stimulate other organs, such as the brain, stomach and/or bladder. + UCLA Via Bleeping Computer Images via Islam Mosa/University of Connecticut and Maher El-Kady/UCLA , Pixabay

Comments Off on MIT’s New Glucose Fuel Cell is Powered by the Human Body

A team of engineers from MIT has developed a new glucose fuel cell that runs on the same sugar that powers the human body. The team believes that the device will be able to “drive highly efficient brain implants” that would enable paraplegics to regain control of their limbs. The device, which is detailed in the June 12 edition of the journal  PLoS ONE , strips electrons from glucose molecules in order to generate a small electric current.

Comments Off on Scotland to Recycle Old Diapers and Turn Them Into Furniture!

Each year over 160 million diapers (or nappies as they are known in the UK) are sent to Scotland’s landfills. However a new recycling scheme is aiming to take those used diapers and turn them into park benches, garden furniture, decking, bollards, railway sleepers, fencing, roof tiles and cardboard. Other bathroom waste will also be recycled, including incontinence products, wet wipes, nappy sacks and cotton wool. Read the rest of Scotland to Recycle Old Diapers and Turn Them Into Furniture!
