A contact lens with a sensor region are described. The contact allows for normal vision and a concentric ring around the vision area of the lens includes one or more sensors for detecting changes in the interocular pressure of the eye. The data may be scanned using a camera, or in some embodiments, the data may be transmitted using a micro antenna in the sensing region. The data may be analyzed using a software application on a cell phone or other computing device.

Device surfaces are rendered superhydrophobic and/or superoleophobic through microstructures and/or nanostructures that utilize the same base material(s) as the device itself without the need for coatings made from different materials or substances. A medical device includes a portion made from a base material having a surface adapted for contact with biological material, and wherein the surface is modified to become superhydrophobic, superoleophobic, or both, using only the base material, excluding non-material coatings. The surface may be modified using a subtractive process, an additive process, or a combination thereof. The product of the process may form part of an implantable device or a medical instrument, including a medical device or instrument associated with an intraocular procedure. The surface may be modified to include micrometer- or nanometer-sized pillars, posts, pits or cavitations; hierarchical structures having asperities; or posts/pillars with caps having dimensions greater than the diameters of the posts or pillars.

A substrate subject to degradation at temperatures above 100° C. is coated with a nanostructured ceramic coating having a thickness in excess of 100 nm, formed on a surface of the substrate, wherein a process temperature for deposition of the nanostructured coating does not exceed 90° C. The coating may be photocatalytic, photovoltaic, or piezoelectric. The coating, when moistened and exposed to ultraviolet light or sunlight, advantageously generates free radicals, which may be biocidal, deodorizing, or assist in degradation of surface deposits on the substrate after use. The substrate may be biological or organic, and may have a metallic or conductive intermediate layer.

A production method for a joined object is a method for producing a joined object by joining two objects together. The method includes: irradiating joining surfaces of the respective two objects with plasma; and bonding the joining surfaces irradiated with plasma, at a temperature lower than a melting point of a substance included in the objects.

A method of modifying a 3D-printed polymer structure is provided. The method can include providing an initial 3D-printed polymer structure having at least one exposed surface; treating the exposed surface of the initial 3D-printed polymer structure with plasma to obtain a treated 3D-printed polymer structure having a treated surface; administering an adhesive to the treated surface of the treated 3D-printed polymer structure; and contacting a complementary 3D-printed polymer structure with the treated surface of the treated 3D-printed polymer structure to obtain a modified 3D-printed polymer structure.
