This study presents a novel and precision process to fabricate microneedle. The process includes microlens array mask with the contact printing in ultraviolet (UV) lithography. The tip of micro tapered cone microneedle utilizes the microlens array mask with geometrical optics. Due to the light pass through a plano convex microlen, a microlen have a focal point. An optical system is set up to characterize...
This study aims to produce a high fill factor microlens with a specific tilt angle and uses it to enhancing the brightness of film with a light-emitting component. The lens tilting effect of the high fill factor microlens can alter the light path and collect uniform lateral light or guide light to one side, allowing light-emitting components to be applied in uniform scenarios. TracePro optical simulation...
Pyrolytic carbon materials contain high internal surface area, desirable pore structure, and controlled surface functionalities, making them effective for gas purification, separation, storage, and chemical reactions. This research describes a two-step (i.e., photolithography and pyrolysis) procedure to integrate suspended porous carbon membranes on C-MEMS from SU-8 photolithography precursor. The...
