In the future, working up a sweat by exercising may not only be good for your health, but it could also power your small electronic devices. Researchers have designed a sensor in the form of a temporary tattoo that can both monitor a person's progress during exercise and produce power from their perspiration.
Researchers have used nanoimprinting methods to make patterned polymeric films with surface topography inspired by that of a rose petal, producing a range of transparent films with high water pinning forces.
A team of materials chemists, polymer scientists, device physicists and others today report a breakthrough technique for controlling molecular assembly of nanoparticles over multiple length scales that should allow faster, cheaper, more ecologically friendly manufacture of organic photovoltaics and other electronic devices.
A new technique which traps light at the nanoscale to enable real-time monitoring of individual molecules bending and flexing may aid in our understanding of how changes within a cell can lead to diseases such as cancer.
