Unlike traditional focalization that recruits multiple moving lens elements to adjust focus, liquid lenses deliver adaptive focusing by simply tuning the surface profile of or elastomer encloses liquid. Its simple and compact configuration, low cost, actuation efficiency promise wide industrial, medical, consumer applications. Dielectric elastomers (DEs), one type commercially available soft active material, have been a good fit for creating optics. In this Letter, we present an adaptive,...
We conducted a prospective randomised controlled trial of 137 patients with massive peptic ulcer haemorrhage over period 12 months to compare the haemostatic effects endoscopic heat probe thermocoagulation and pure alcohol injection. Seventy eight (56.9%) were in shock at time randomisation trial. The age, sex, number shock, haemoglobin value entry trial, severe medical illness, location bleeders, stigmata recent comparable among probe, alcohol, control groups. initial effect was better than...
An optofluidic device named the “Insect–Human Hybrid Eye” (IHHE), which combines architectural merits of both human camera eyes and insect compound eyes, is presented to implement imaging with a large angle view adaptive focusing along any direction within field.
Liquid lens offers a simple solution to achieve tunable optical powers. This approach, however, suffers from deteriorated resolution at high diopters. In this study, plano-convex liquid with aspherical cross-section is developed. Such configuration allows for the profiles diopters be close spherical shapes by alleviating edge-clamping effects. Resolution tests of 6mm optimized asphericity exhibit improved resolutions in both center and peripheral regions 40 100 than lenses planar membranes....
Mechanical stretching and topographical cues are both effective mechanical stimulations for regulating cell morphology, orientation, behaviors. The competition of these two remains largely underexplored. Previous studies have suggested that a small cyclic strain is not able to reorient cells been pre-aligned by relatively large linear microstructures, but can those micro/nanostructures if the characteristic dimension structures below certain threshold. Likewise, with given dimension, must...
Most of currently employed laparoscopes use a single and non-tunable solid lens to visualize the surgical environment during minimal invasive interventions. These devices are limited due loss depth perception, fixed view direction narrow field-of-view (FOV). In this study, three-dimensional deformable liquid array with adaptive focusing directional capability is developed. Miniature lenses sealed by membranes arranged on flexible substrate. During operation, substrate where reside driven...
We present a membrane sealed fluidic lens that is hydrostatically connected to concentric ring-shaped electroactive elastomer. Electrical activation deforms the elastomer, which induces fluid passage between part and actuation of membrane. This changes lens's shape therefore focal length. The length ranges from 25.4 mm 105.2 can be obtained with voltage bias 1.0 kV. Comparing existing lenses driven by polymers, this has wider range refractive power at significantly lower voltage. Our device...

We present a smartphone based microscope using elastomer liquid lens as the objective to achieve adjustable magnification without displacement or replacement. The is small enough fit into pocket wallet and can work with cameras. Instead of an membrane constant thickness, varied thickness profile used reduce working pressure for improved reliability. Compared existing microscopes, this allows needs compromising miniaturization. It thus promises potential applications in point-of-care...
Adaptive elastomer-liquid lens can find a variety of optical applications due to the tunable powers without additional replacement or displacement. Most current lenses use elastomer membrane with constant thickness. This approach, however, suffers from substantial aberration edge clamping effect. In this study, varied thickness customized aspherical profile is designed and developed encapsulate plano-convex liquid lens. Such fabricated by double-side replica molding against deformed...
