Researchers have developed a battery-free sensor that reacts to sound waves, such as particular spoken words, producing enough vibrational energy to power an electronic device. The novel sensor would ...

Sensors that monitor infrastructure, such as bridges or buildings, or are used in medical devices, such as prostheses for the deaf, require a constant supply of power. The energy for this usually ...

The brilliant metallic blue wings of Morpho butterflies dazzle the eye. Branched nanostructures on the wings scatter light in complex ways to produce this characteristic iridescent hue. By harnessing ...

Although the ability tends to wane as we get older, the human auditory system is pretty good at filtering out background noise and making a single voice able to be understood above the general hubbub ...
