September 4, 2012 4:10 am | News | Comments

A "magic carpet" which can immediately detect when someone has fallen and can help to predict mobility problems has been demonstrated by University of Manchester scientists. Plastic optical fibers, laid on the underlay of a carpet, can bend when anyone treads on it and map, in real time, their walking patterns.

Nanoinverters are created with low-cost additive manufacturing process

August 27, 2012 6:59 am | by Angela Herring | News | Comments

A crit­ical ele­ment in any microchip is an inverter—an elec­tronic com­po­nent that spits out zeros when it is given ones, and vice versa. Complementary metal-oxide-semiconductor, or CMOS, is the industry standard for this type of component, but still requires billions of dollars to achieve production scale. Researchers have recently pioneered a room-temperature additive process that creates a nanoscale inverter quickly and at low cost.

Merging tissue and electronics

August 27, 2012 3:33 am | by Anne Trafton, MIT News Office | News | Comments

To control the 3D shape of engineered tissue, researchers grow cells on tiny, sponge-like scaffolds. These devices can be implanted into patients or used in the laboratory to study tissue responses to potential drugs. A team of researchers has now added a new element to tissue scaffolds: electronic sensors. These sensors could be used to monitor electrical activity in the tissue surrounding the scaffold, control drug release, or screen drug candidates for their effects on the beating of heart tissue.


3D theater breakthrough eliminates need for glasses

August 24, 2012 5:17 am | News | Comments

To create modern 3D effects, movie theaters use linearly or circularly polarized light sourced from two projectors that simultaneously display two similar, slightly offset, images. This approach is cumbersome and still needs the help of glasses, so a team of South Korean investigators have refined a parallax barrier method that can be used to create a 3D effect with a single screen.
