The springs are what determine whether a particular sound sets the sensor in motion. The researchers see many potential applications for their battery-free, sound-powered sensor. It could be used ...

It is the springs that determine whether or not a particular sound source sets the sensor in motion. Potential use cases for these battery- free sensors include earthquake or building monitoring.

code embedded on the page could then use the phone's motion and orientation sensors to correctly guess the users' PIN. This worked on the first attempt 75 per cent of the time, and by the third ...

Writing about it makes it sound complicated, but in reality, automating the Outdoor Motion Sensor's behavior takes just a few minutes once you know just what you want it to control. If you don't ...
