چکیده
In this paper the effect of parametric amplification in MEMS-based air-flow hairsensors is studied. With an AC-voltage controlled torsional stiffness the rotation of the hair can be influenced. With the appropriate amplitude, phase and frequency, the rotation of the torsional hair system is increased with respect to the case without parametric amplification. Therefore, parametric amplification is identified as a method to improve the performance of MEMS-based hair air flow sensors.

Parametric Amplification and Stochastic Resonance in Bio-Inspired Hair Flow Sensors
Inspired by crickets and its perception for flow phenomena (figure 1), artificial hair flow sensors have been developed successfully in our group [1]. The realization of array structures and improvement of fabrication methodologies have led to better performance, making it possible to detect and measure flow velocities (illustrated in figure 2) in the range of sub-mm/s [2]. To improve the perfo...
متن کاملComparing signal amplification of thiocyanated Gold nanoparticles in the presence of different ions
Detecting is the most important section in all kinds of sensors. In this regard, the amplification of surface plasmon resonance intensity of gold colloids nanoparticles (GNPs) was studied in the presence of several ions. GNPs were synthesized and then capped by thiocyanate and characterized via DLS and TEM image. In the next step the effect of different concentrations of ions such as iron, copp...
