Abstract
A pressure sensing film includes first and second films. The first and second films are configured to form an optical cavity therebetween. A flexible transparent film is arranged in the optical cavity. The flexible transparent film is compressible in response to a pressure change in air adjacent the pressure sensing film. A pressure sensing device and a method of sensing pressure adjacent a surface are also disclosed.
