Nanoarray-Enhanced Micromechanical Pressure Sensor with Remote Optical Readout

Abstract

We demonstrate a compact implantable intraocular pressure (IOP) sensor with remote optical readout for glaucoma research and patient management. Using non-invasive white light, we excite the sensor's pressure-sensitive optomechanical cavity and detect the reflected light, whose optical signature changes as a function of IOP. The sensor has provided robust measurements of hydrostatic pressure between 10-60 mmHg with an accuracy of 0.15 mmHg.
