Two types of aluminum oxide (Al 2 O 3 ) modified microcantilevers (MCLs) were tested for their sensitivity and reproducibility for detection of low levels of moisture. Aluminum was sputtered on the MCLs and oxidized to Al 2 O 3 through thermal oxidat

We have demonstrated that the Al 2 O 3 -modified microcantilevers (MCLs) can be used to detect low level of moisture. The detection limit for moisture in nitrogen was 10 ppm. The MCLs’ response time to moisture was less than 3 min. The sensors were

In this paper, we report a controlled architectural growth of ultrathin films of conducting polymers via layer-by-layer (L-b-L) self-assembly with poly(3, 4-ethylenedioxythiophene), poly(styrenesulfonate) (PEDOT-PSS), and polypyrrole (PPy) as alterna

A simple approach is developed to obtain scum-free pattern transfer in SU-8 resist by UV-lithography for electroforming applications. SU-8 is an epoxy-based negative resist used in the fabrication of high-aspect ratio microstructures. SU-8 resist pos
