Solar cell creates power from sun and rain

Engadget reports on the development of new solar cell technology that could allow solar panels to generate power from both sunlight and rain, by incorporating a thin layer of graphene. The approach has some way to go before becoming viable but it could encourage wider instalation of solar panels in climates with more variable weather.

Smart diabetes patch monitors blood sugar and delivers insulin


Engadget features a prototype diabetes patch that monitors blood sugar levels and releases insulin when required. The early-stage smart patch measures the wearer’s temperature along with pH and chemicals released in perspiration and administers the right amount of insulin when needed.


Graphene water filters – fast and effective

Inhabitat features the development of a graphene water filter that is much faster than existing solutions, and can filter out anything larger than one nanometer, including bacteria and viruses.


Graphene & soda-lime glass could improve solar cells, OLEDs


CleanTechnica reports on research at Brookhaven National Laboratory that has stumbled upon a way to integrate graphene efficiently into soda-lime glass, which could lead to cheaper and more efficient solar panels:

“…graphene’s high conductivity and transparency make it a very promising candidate as a transparent, conductive electrode to replace the relatively brittle and expensive indium tin oxide (ITO) in applications such as solar cells, organic light emitting diodes (OLEDs), flat panel displays, and touch screens.”


Graphene Research Shows Potential For Brain Implants

TechCrunch reports on research into the use of graphene for brain implants: “it could be used to make highly effective, flexible brain implants in future — biodevices that avoid the loss of signal problem associated with the scar tissue that can form around modern electrodes made from more rigid substances, such as silicon and tungsten.”

Although graphene implants would require much further research (including regarding toxicity) graphene electrodes could allow “the restoration of sensory functions for amputee or paralysed patients, for example, or to help individuals with motor disorders such as epilepsy or Parkinson’s disease.”
