The next cyberattack could come from sound waves

You might think your smartphone or laptop is relatively safe from cyber attacks thanks to anti-virus and encryption software. But your devices are increasingly at risk from "side-channel" attacks, where an intruder can bypass ...

Accelerometer

An accelerometer measures the acceleration it experiences relative to freefall. Single- and multi-axis models are available to detect magnitude and direction of the acceleration as a vector quantity, and can be used to sense orientation, vibration and shock. Micromachined accelerometers are increasingly present in portable electronic devices and video game controllers.
