Genius inventor John A Rogers and his research group have produced the first flexible stretchable adhesive electronic device that can be applied to the skin. Epidermal electronic systems - EES. Initially designed as a biological sensor the electric tattoo has potential to be much more than an expression of difference or rebellious body art. Biologic sensors built-into the device can detect brain waves, muscle activity, temperature and monitor for heart arrhythmia. Looking like a crumpled spiderweb the device combines flexible electronics with clever flexible wiring, giving the electronic tattoo staying power. Using Radio Frequency Identification, ESS can be used to non-invasively track patients for progress , and possibly minimizing medication or surgical mistakes. The sensing functions allow basic body function to be measured wirelessly.
The snake-like connectors link electronic components acting like extension leads, where as wires on a circuit board tend to be straight – limiting the amount of movement
– Rogers clever snake-like wires allow movement and flexibility. Using bendy wires as part of the design is clever engineering, the work done to make the electronic component flexible now that is genius. Read the full article »»»»

Researchers at Georgia Institute of Technology have demonstrated - at the IEEE conference July 6 - technology capable of harnessing ambient electromagnetic energy that pervades our modern world. By taking advantage of the transmitters that are already covering modern cities power is extracted from thin air. In a sense turning mobile phone base stations, tv transmitters and radio station transmitters into micro power stations. While this technology only provides very small amounts of power it is enough to power simple sensors and devices, eventually as the technology develops more advanced electronics may be powered, we may eventually see self-powered bumper stickers telling us to back the f off.
“There is a large amount of electromagnetic energy all around us, but nobody has been able to tap into it,” said Manos Tentzeris, a professor in the Georgia Tech School of Electrical and Computer Engineering who is leading the research. “We are using an ultra-wideband antenna that lets us exploit a variety of signals in different frequency ranges, giving us greatly increased power-gathering capability.” Read the full article »»»»
