Abstract
A non-invasive intraocular pressure sensor adapted to be configured on an eyeball is provided. The non-invasive intraocular pressure sensor includes a sensing unit and a readout circuit. The sensing unit includes a plurality of electrode layers and a dielectric layer. The dielectric layer encloses the electrode layers and fills therebetween, and the electrode layers and the dielectric layer form a capacitor. A variation of capacitance of the capacitor varies with a variation of an intraocular pressure of the eyeball. The readout circuit is electrically connected to the sensing unit.
