Fabricating optical lenses by inkjet printing and heat-assisted in situ curing of polydimethylsiloxane for smartphone microscopy.
We present a highly repeatable, lithography-free and mold-free method for fabricating flexible optical lenses by in situ curing liquid polydimethylsiloxane droplets on a preheated smooth surface with an inkjet printing process. This method enables us to fabricate lenses with a focal length as short as 5.6 mm, which can be controlled by varying the droplet volume and the temperature of the prehe...

Shape-morphing systems can be found in many areas, including smart textiles, autonomous robotics, biomedical devices, drug delivery and tissue engineering. The natural analogues of such systems are exemplified by nastic plant motions, where a variety of organs such as tendrils, bracts, leaves and flowers respond to environmental stimuli (such as humidity, light or touch) by varying internal tur...

Spatiotemporal Multiplexing for Fast 3d Confocal Microscopy Using Acoustic Tunable Lenses
Fast optical imaging of three-dimensional (3D) specimens is pivotal for the understanding of fundamental processes in life sciences. In most cases, 3D imaging is performed by acquiring a stack of 2D sections each at a different focal position. Notably, contrast and 3Dreconstruction accuracy are maximized with decreasing the optical thickness of 2D sections. This has spurred the development of s...
