In many Internet of Things (IoT) applications, minimizing power consumption is a key design requirement. IoT capability involves adding sensors and connectivity to a valve or similar device in a ...

One of the biggest challenges for wireless sensor networks is that of power. Solar panels usually produce less power than you hoped, especially small ones, and designing super low power circuits is ...

The $50 sensor runs on two coin cell batteries so you don’t need a nearby power source for installation. The $50 sensor runs on two coin cell batteries so you don’t need a nearby power source for ...

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 ...

A directional coupler is used to sample a small amount of input signal power for measurement purposes. Port 1 is the input port; port 2 is the output port; port 3 is the coupled port; port 4 is the ...

Dirty little secret time: although amateur radio operators talk a good game about relishing the technical challenge of building their own radio equipment, what’s really behind all the DIY gear is the ...

More efficient, smaller, and lighter traction inverters for EVs can be created by integrating current sensors directly into SiC-based power modules. Silicon Austria Labs (SAL), a power semiconductor ...
