For continuously gathering information on ocean conditions, one thing that's been proposed is a network of sensors that would transmit data from the sea floor. Changing their batteries, however, could ...

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 ...

(Nanowerk News) 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 ...

Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Scientists have now used Japan's extensive network of Global ...

University of Michigan researchers have shown that sound waves can be used to hack into devices that use a commonly deployed piece of silicon called a MEMS accelerometer. Fitbits, smartphones, and a ...

Earlier this year researchers developed sensing protocols that allow optical fibers to 'listen' outside an optical fiber where they cannot 'look', based on an interplay between light waves and ...

It's tempting to assume that the sensors on your mobile devices are trustworthy. Surely something that relies on real-world activity can't lie, right? Unfortunately, that's no longer the case.

Global Navigation Satellite System (GNSS) receivers help with precise location tracking and can detect disturbances in the upper atmosphere (ionosphere) by measuring delays and changes in ...
