| Microbot muscles: Chains of particles assemble and flex Posted: 10 Nov 2014 12:09 PM PST In a step toward robots smaller than a grain of sand, researchers have shown how chains of self-assembling particles could serve as electrically activated muscles in the tiny machines. |
| Noise in a microwave amplifier is limited by quantum particles of heat Posted: 10 Nov 2014 09:40 AM PST Scientists have demonstrated how noise in a microwave amplifier is limited by self-heating at very low temperatures. The findings can be of importance for future discoveries in many areas of science such as quantum computers and radio astronomy. Many significant discoveries in physics and astronomy are dependent upon registering a barely detectable electrical signal in the microwave regime. |
| New technique for generating electricity Posted: 10 Nov 2014 05:34 AM PST Research scientists have demonstrated a new technique for generating electrical energy. The new method can be used in harvesting energy from mechanical vibrations of the environment and converting it into electricity. Energy harvesters are needed, for example, in wireless self-powered sensors and medical implants, where they could ultimately replace batteries. In the future, energy harvesters can open up new opportunities in many application areas such as wearable electronics. |
