Toward a minituarized low-power micromechanical electronic nose

An electronic nose based on an array of vibrating doubly clamped beams is proposed. These very high aspect ratio (length/thickness) suspended resonators can be individually functionalized by applying polymer coatings with an inkjet printing approach. The absorption of volatile compounds induces a swelling of the polymers that result in axial...

High performance surface plasmon resonance sensor based on two dimensional ultra-thin metal nanoslit arrays

We present a high performance surface plasmon resonance (SPR) sensor based on two dimensional (2D) ultra-thin (40 nm) gold nanoslit arrays. These structures were designed to exhibit narrow linewidth (FWHM) and high transmission SPR under non-polarized illumination. In addition, we show the influence of the geometrical design on the performance...
