Separating the motion of a system of particles as the motion of the centr e of mass, (i.e., the translational motion of the system) and motion about (i.e. relative to) the centre of mass of the system is a useful technique in dynamics of a system of particles.

A chemical sensor is a device that transforms chemical information, ranging from concentration of a specific sample component to total composition analysis, into an analytically useful signal. This very general definition does not really agree with the popular view on sensors in general.
In this module, we cover the basics of electrochemical sensors, gas sensors, and biosensors. ELECTROCHEMICAL SENSORS. Electrochemical sensors are made up of three essential components: a receptor that binds the sample, the sample or analyte, and a transducer to convert the reaction into a measurable electrical signal.
