John A. Rogers, the Lee J. Flory-Founder professor of engineering at the University of Illinois, and his team of researchers, have developed a temporary tattoo-like patch that combines electronic components and can be mounted directly onto the skin. The device can be used for communications, medical diagnostics and human-machine interfaces, according to an article in ScienceNewsline. Due to the serpentine shape of the circuitry, the patch is flexible and comfortable and will bend and stretch along with the wearer’s skin.
The patches are mounted onto a thin sheet of water-soluble plastic, which can be laminated onto the skin just as easily as a temporary tattoo. If you prefer your wearable electronics to be less obvious, the electronic components can be applied directly to a temporary tattoo and then applied to the skin.
3-D Printed Houses
What building contractor doesn’t want to construct real estate quickly and economically? One company that’s tough to beat is Shanghi-based WinSun Decoration Design Engineering, which recently created 10 3D-printed houses, in just one day, according to a China Real Time report. Each home cost under US$5,000. The giant 3-D printed was 100 feet long, 33 feet wide and more than 20 feet tall. The houses were printed in parts, made from glass fiber and high-grade cement, which were later pieced together.
According to WinSun, the 3-D built homes cost less than half the price of a house built using traditional methods. But in spite of the cost-effectiveness, regulatory issues will prevent this technique from becoming practical any time soon.
Brain-controlled Exoskeleton to Kick off World Cup 2014
The 2014 World Cup Football Championship starts Brazil this June, but it won’t be one of the soccer making the first kick-off, instead, it will be a paraplegic teenager who will be using a brain-controlled exoskeleton.
The exoskeleton, created by an international collaboration called Walk Again, is attached to the lower body and is maneuvered using brain activity. Electrodes attached to the scalp pick up brain impulses and transmit them wirelessly to the exoskeleton suit, which converts them into commands and produces motion. The suit also includes sensors to monitor touch to provide feedback to the wearer via vibrating motors and visual displays, to make the experience feel more natural.
