    • An apparatus (180) for measuring intraocular pressure (IOP) comprises a contact lens (40) including an inner surface (42) contoured to a surface portion (34) of an eye (36) and a sensor (10) disposed in the contact lens. The sensor (10) comprises a contact surface (14) for making contact with the surface portion (34) of the eye (36). The contact surface (14) includes an outer non-compliant region (16) and an inner.compliant region (18) fabricated as an impedance element that varies in impedance as the inner compliant region changes shape. The sensor (10) further comprises a region of conductive material (38) electrically coupled to the impedance element of the compliant region (18) and responsive to an external signal for energizing the impedance element so that the IOP may be determined.
    • 一种用于测量眼内压(IOP)的装置(180)包括隐形眼镜(40),所述隐形眼镜包括形成于眼睛(36)的表面部分(34)的外表面(42)和设置在所述触点 镜片。 传感器(10)包括用于与眼睛(36)的表面部分(34)接触的接触表面(14)。 接触表面(14)包括外部非顺应性区域(16)和制造为随着内部顺应性区域改变形状而阻抗变化的阻抗元件的内部区域(18)。 传感器(10)还包括电耦合到柔性区域(18)的阻抗元件的导电材料(38)的区域,并且响应于外部信号来激励阻抗元件,使得可以确定IOP。
