While the general principle of a radar is to emit a radio signal toward a target and analyze the reflected signal, there are different types. In continuous wave (CW ... the Passive Infrared (PIR) ...

Image sensors are built into every smartphone and every digital camera. They distinguish colors in a similar way to the human ...

Furthermore, we observe that the so far constant assumed factor to convert the sensor signal to the beam’s displacement depends on the dissipated power within the actuator, as well as on the dynamic ...

This study presents an advanced self-powered sensor for CO2 monitoring using surface acoustic wave technology, enhancing ...

Electrochemical aptamer-based (EAB) sensors are capable of measuring the concentrations of specific molecules in vivo, in real time, and with a few-second time resolution. For their signal ...
