If you want to know more than one thing, you need more than one sensor. In fact, many engines today have not just two oxygen ...
A new solid-state quantum sensor developed by researchers at the Massachusetts Institute of Technology ...
Abstract: The length of an open- or short-circuited wire is linearly proportional to the capacitance or inductance of the wire, respectively. Several types of simple and inexpensive circuits are ...
Abstract: This paper presents an optical fiber sensor, that uses surface plasmon resonance on metallic wires to directly and simultaneously measure both the refractive index and the temperature. The ...
