A noise reduction system includes a driving device, a sensing device, a first switch, a second switch, and a controller. The tear-away energy absorbing webbing has a top layer load-bearing web and a bottom layer load-bearing web. The inflatable separation device includes an inflatable support frame and a cover that envelops the support frame and forms an enclosed interior space when the support frame is inflated. The blocking capacitor is selected to substantially increase an amplitude ratio of the down-converted signal to the amplified receive signal to substantially increase the front-end gain of the receiver. Sensor can be fabricated with substantially optimized sensor volumes to generate a response having a substantially maximized signal to noise ratio upon introduction of a fluid containing one or more target analytes.
