摘要： Systems, methods, and computer program products for measurement of surface properties using a mobile device are described, the surface properties including interfacial (surface) tension, contact angle (static, advancing, or receding), solid surface energy, and rolling or sliding angle on an inclined surface. The system has a support adapted to receive a mobile device with a camera and a processor. A structure is coupled to the support that is adapted to removably receive measurement components. The measurement components are configurable to place a droplet or a bubble within a field of view of the camera. Software on the mobile device is configured to operate the camera to take an image of the droplet or the bubble within the field of view of the camera, and to determine one or more physical properties of the droplet or the bubble based on an analysis of the image.

摘要： A variable focus lens comprising: at least two substrates having a gap defined therebetween; a fluid material disposed between the at least two substrates to form a fluid bridge with a fluid bridge interface, the fluid material having a predetermined volume; and wherein at least one of a magnitude of the gap, the predetermined volume, curvature of the at least two substrates, wettability of the at least two substrates, and electrical stress state on the fluid bridge interface determines a working distance of the lens.
