The manipulation and detection of living cells are essential requirements for many applications in biology, biotecnology and medicine. In this study, we propose a microfluidic device, which facilitated of a differential capacitively coupled contactless conductively detection (DC4D) coplanar capacitor structure and a dielectrophoresis (DEP) concentrator based on circular electrodes for detecting of...
In this paper, a novel design of a differential capacitively coupled contactless conductivity detection (DC4D) sensor with thin polydimethylsiloxane (PDMS) protective layer has been developed for detection of objects in microfluidic channel. The capacitive sensor consists of four adjacent electrodes which are arranged to form differential coplanar capacitor structures in order to achieve a high sensitivity...
This work presents a novel algorithm using wavelet transform and principal component analysis for face and hand gesture recognition on digital images. The testing results of the proposed algorithm are presented. Based on the testing results, it is shown that the proposed algorithm gives an effective performance of face recognition and hand gesture recognition on digital images. In this paper, we also...
A bonding technique, capable of sub-micron and finer alignment accuracy, has been developed for electronics-optics heterogeneous integration applications. The technique is based on the principle of misalignment self-correction using bump (convex) and hollow (concave) elements, to align one die (i.e. a chip) to another one (i.e. a substrate) during the stacking process. Conductive hollow pad and Au...
