Strechable and washable Printed Electronic circuit


Researchers have successfully incorporated washable,  and stretchable electronic circuits into fabric, opening up new possibilities for smart textiles and wearable electronics. The circuits were made with cheap, safe and environmentally friendly inks, and printed using conventional inkjet printing techniques. 
The researchers, from the University of Cambridge, working with colleagues in Italy and China, have demonstrated how graphene – a two-dimensional form of carbon – can be directly printed onto fabric to produce integrated electronic circuits which are comfortable to wear and can survive up to 20 cycles in a typical washing machine
The new textile electronic devices are based on low-cost, sustainable and scalable inkjet printing of inks based on graphene and other two-dimensional materials, and are produced by standard processing techniques.

Most wearable electronic devices that are currently available rely on rigid electronic components mounted on plastic, rubber or textiles. These offer limited compatibility with the skin in many circumstances, are damaged when washed and are uncomfortable to wear because they are not breathable.

here figure shows how gate, source and drain termianals combinedly formed FET device as it is the fastest switching device amongst all other power electronics devices, it wouls results in faster operation and more versatality.

“The printed components are flexible, washable and require low power, essential requirements for applications in wearable electronics,” said PhD student Tian Carey, the paper’s first author.

Bio-Solar panel

The scientists, at Imperial College London and University of Cambridge, have successfully Developed a new biophotovoltaic cell. "This Biophotovoltaic device is biodegradable and it can be serve as a disposable solar panel in the future and battery that can decompose in our composts or gardens,"  Co-author Marin Sawa at University of Arts London and Imperial College London told  Phys.org . "Cheap, accessible, environmentally friendly, biodegradable batteries without any heavy metals and plastics—this is what we and our environment really need but don't have just yet, and our work has shown that it is possible to have that." In general, biophotovoltaic  cells  contain some type of cyanobacteria or algae that is phototrophic, meaning it converts light into energy. However, even in the dark these organisms continue to generate some energy by metabolizing their internal storage reserves. So when the organisms are connected to a non-biological electrode, t...

Superstrong MicroBot

Here is Introducing MicroTug Developed by biomimetics and dexterous Lab. This 12 gram of micro robot uses "controllable adhesive" surface plate which sticks to the surface only when shear pressure is applied. it is capable of pull the objects 2000 times its own weight. "This is equivalent of a human adult dragging a blue whale around on land" They said . Main goal of the project is to create a robot that can be useful to drag the heavy objects where human can't reach. Here is the video which shows simple working demonstration of Robot  pulling heavy weight. Courtesy

New Way to secure the Internet more reliably by Quantum physics

Image
scientists have developed a high-speed encryption system called "Quantum key distribution" (QKD) to stop hacker.  System is capable of distributing the encryption codes at the rate of MB/s which 10x faster than present method.  In a study of journal science advance  Here the researchers demonstrate that the technique is secure from common attacks, even in the face of equipment flaws that could open up links.
