Microelectromechanical system (MEMS) directional microphones have been identified as having use in multi-projected virtual reality applications such meetings for projecting cameras. In these applications, the acoustic sensitivity plays a vital role it biases sensing, signal-to-noise ratio (SNR) and self-noise. The is multiplied outcome of mechanical electrical sensitivity. As dimensions are lim...

This work demonstrates with numerical simulations, the feasibility of a wide frequency range and high pressure level piezoresistive microphone based on MEMS technology. An accurate lumped-element model was used to optimize the microphone dynamic response. Mechanical lumped parameters were extracted from structural finite element method (FEM) simulations, while squeeze film fluid parameters were...

Hearing aids are not a one-size-fits-all solution to hearing problems; they must be uniquely tuned for each wearer. There are currently no low-cost and/or effective methods for in situ tuning. This paper describes a microelectromechanical-systems MEMS -based dual omnidirectional microphone that can be tuned by growing metallic nanostructures. The nanostructures are grown on integrated solid ele...
