Precise Sensing Diaphragm

LSU Reference: 1005


  • Under Patent Prosecution


This invention is an innovative type of sensing diaphragm that can be incorporated into a sensor. The advanced design allows it to detect pressure changes as small as one Pascal. The diaphragm can be micrometer sized and can sense the differential pressure between two points in both air and liquid media. The materials used in the diaphragm are low cost and biocompatible. Though experiments have focused on pressure, this invention also has potential to measure other forces like strain. The technology can be used to easily manufacture diaphragms of various sizes and patterns for different sensitivities depending on the application.
