Highly Nonlinear SolitaryWave Transducers for Detecting Eye Pressure Changes

Utilizing a highly nonlinear solitary wave (HNSW) transducer, it is possible to sense the intraocular pressure (IOP) of an eye. A miniature transducer that captures HNSWs has the potential to be utilized at the point-of-care for patients and for self administered monitoring of IOP. It is possible to mimic a human eye using a Polydimethylsiloxane (PDMS) cornea that is pressurized to 10mmhg, 20mmhg, and 30mmhg. The HNSW response, when tested on PDMS at the three different pressures, are unique waves with distinct features. These features can be extracted from each signal and compared to verify whether HNSWs provide enough differentiation between IOPs which would allow for correct identification.
