Abstract:
1. A method for sensing pressure, the method comprising: establishing a gap between first and second membranes at a first pressure, the first and second membranes comprising nanophotonic components; transmitting a first beam of light to the nanophotonic components; measuring a first reflectance of the light off of the nanophotonic components at the first pressure and determining a first resonance by detecting a dip in reflectance; changing the gap between first and second membranes in response to a second pressure; transmitting a second beam of light to the nanophotonic components; measuring a second reflectance of the light off of the nanophotonic components at the second pressure and determining a second resonance by detecting a dip in reflectance; and calculating the second pressure using the difference between the first resonance and second resonance.
