A new concept for the realization of a refreshable Braille cell is presented. An
electrothermally controlled microactuator that exploits the hydraulic pressure due to the …

A method to fabricate microlens arrays in polymer substrates via hot embossing is presented
in this paper. The partial-filling hot embossing technique of micro cavities on a mold insert …

This paper reports an innovative technique for rapid fabrication of polymeric microlens
arrays based on UV roller embossing process. In this method, a thin flat mold is fabricated by …

Microfabrications of polymer are becoming increasingly important and considered as a low-
cost alternative to the silicon or glass-based Micro-Electro-Mechanical System (MEMS) …

Micro fabrication of polymers is becoming increasingly important and is considered a low-
cost alternative to silicon-or glass-based MEMS technologies. However, very little work has …

The cycle time of conventional hot embossing can reach as long as 10 min due to its
periodically heating and cooling steps. In recent years, researchers around the world had …

We report on large-surface-area micro-patterning of a bulk chalcogenide glass by a PDMS
soft mould. Micrometre-scale (width~ 4μm and depth~ 0.8 μm) test patterns such as ribs …

Polymer surface modification is a key step in manufacturing for applications of parts in
biotechnology, catalysis, sensing, and other fields. However, functionalization approaches …

We demonstrate, for the first time, time-and cost-effective replication of sub-micrometer
features from a soft PDMS mold onto a bulk chalcogenide glass over a large surface area. A …

This article discusses the effect of conventional electrical discharge machining (EDM)
parameters for generating micrometer and submicrometer leveled surface roughness …
