Negative-Poisson’s-Ratio (NPR) Microstructural Material by Soft-Joint Mechanism

Lu Y-W, Chang C-J, Lin P-T, Gea H-C, Rutgers University, US

We present an example of making a negative-coefficient material - Negative Poisson’s Ratio (NPR) material, which expands in the cross section when stretching. The NPR materials can provide unique characteristics in energy absorption. The NPR [...]

Regular Nano-Pores Fabricated By UV Cross-Linking Non-softbaked SU-8 Resist In a Solvent Evaporation Controlled Environment

Chang C-J, Tseng F-G, Yang C-S, National Tsing Hua University, TW

This paper proposes a novel technology to fabricate 3D nano pore structures in SU-8 resist, a widely employed resist in MEMS and Bio-chips. Controlling the evaporation rate in SU-8 fabrication process, regular porous structures with [...]
