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 ...

Avoiding the deluge of data created by the deployment of too many sensors requires a more considered approach to sensor selection and integration. Ideally, sensors should deliver just enough ...

Unlike traditional homes, where electronic devices operate independently of each other, in a smart home, there is an infrastructure that connects all the sensors and can access the internet via ...
