Soaps Soap is a mixture of sodium salts of various naturally occurring fatty acids. Air bubbles added to a molten soap will decrease the density of the soap and thus it will float on water. If the fatty acid salt has potassium rather than sodium, a softer lather is the result. Types of Soap: The type of fatty acid and length of the carbon chain determines the unique properties of various soaps.
However, in order to gain acceptance as a method of stress. management in the workplace, wearable sensors must be. minimally obtrusive, so that workers can perform their tasks. with complete freedom, and inconspicuous, to avoid. anxieties associated with wearing medical devices in public.
A sensor's sensitivity indicates how much the sensor's output changes when the input quantity being measured changes. For instance, if the mercury in a thermometer moves 1 cm when the temperature changes by 1 Â°C, the sensitivity is 1 cm/Â°C (it is basically the slope Dy/Dx assuming a linear characteristic). sensor is a type of transducer; sensors may provide various types of output, but typically use electrical or optical signals.
