Abstract—We report on prototype fiber endoscopes with tun-able-focus liquid microlenses integrated at their distal ends and actuated through infrared (IR) light. Tunable-focus microlenses allow minimal back-and-forth movements of the scopes them-selves and different depths of focus (DOFs), thus having spatial depth perception in the obtained images. The liquidmicrolens was formed by a water–oil meniscus pinned at a hydrophobic– hydrophilic boundary at an aperture. IR light-responsive hydrogel microstructures were formed by photopatterning thermo-responsive N-isopropylacrylamide hydrogel with en-trapped IR light absorbing gold nanoparticles. The volumetric change in the hydrogel microstructures regulated the pressure difference across the wa...
