An improved atmospheric packaged SOI resonant pressure sensor is presented. A special anchor structure using suspended connecting truss is developed to suppress the vertical position shift of the resonator when the diaphragm deflects, and a stress isolating structure is introduced to improve the performance of the resonant pressure sensor. Experimental results show that the vertical position shift of the resonator is reduced to only 7.3% compared with conventional anchor design. Over the full scale pressure range of 3.5–280 kPa, the pressure sensitivity is 10.86 Hz/kPa, with the nonlinearity is 0.0138%FS, the hysteresis error is 0.0047%FS, the repeatability error is 0.0071%FS, and the accuracy is better than 0.02%FS.

The current work presents the using of microfluidic hydrodynamic flow focusing for enabling an accurate control of self-assembling nanoparticles. A mixture of surfactant and DNA dispersed in 35% ethanol is focused between two streams of pure water in a microfluidic channel. As a result, a rapid change of solvent quality takes place in the central stream, and the surfactant-bound DNA molecules undergo a fast coil-globule transition. Using this method nanoparticles having a hydrodynamic diameter of 70nm with a polydispersity index below 0.2 were achieved. A second method relied on the controlled diffusive mixing of surfactant and DNA solutions through a water stream of tunable width. Using this method the smallest nanoparticles achieved were about 30 nm in hydrodynamic diameter, meaning that most of them contained a single DNA molecule.

Organic thin film gas sensor based on Zinc hexadecafluorophthalocyanine (ZnPcF16) have been fabricated by spin-coating method. The thin film was then used to study the absorption spectra and morphology using UV-VIS spectrometer. Then the fabricated film has been used as a chemical sensing material for the detection of VOCs (ammonia, acetone, ethanol and methanol) by using a low-cost optical measurement. For getting more insight, Quantum mechanical calculation based on DFT was employed to investigate the interactions between VOCs and sensing molecules.

The effect of surface passivation on tin distribution in Ge1-xSnx(001)/Ge(001) are studied using first principles calculations. The segregation of Sn atoms towards the surface were suppressed when the clean surface is fully passivated with hydrogen adatoms while changing the passivating species to halogen adatoms resulted in enhancing Sn segregation towards the surface. This effect strengthens when moving down the Group-VII elements from fluorine to iodine. For both hydrogenated and halogenated surfaces, aggregation of sn atoms is not favored.

Tunneling field-effect transistor (TFET) is one of the promising candidates to substitute conventional MOSFET for ultra-low power applications. TFETs obey band-to-band tunneling, thus attaining sub-60-mV/dec of the subthreshold swing. However, there is a trade-off of small on-state currents even at high operation voltage. In this work, the SiGe core-shell nanowire TFETs are introduced by showing superior DC characteristics compared to other silicon-based TFETs.

This paper presents an enhanced high-sensitivity micro resonant temperature sensor with axial stain amplification structure. With the external temperature variation, an amplificated axial strain of micro-resonator vibration beam will be produced because of the materials with different thermal expansion coefficients of the micro resonator and package. This will result in a larger resonant frequency shift of the device with temperature change. The theory and analysis of frequency variation is illustrated with temperature sensitivity achieving 309Hz/K. Experimental test shows that actual frequency variation with temperature change of 20K is about 252Hz/K. Simulation match with measurement moderately and can be utilized to optimally design high-sensitivity temperature sensor before the costly fabrication.

In this work, we present the fabrication and characterization of a novel multi-layer noncontact disk-shaped electrostatic microgenerator. The microgenerator aims to harvest kinetic energy from rotary motion in our daily life. The multi-layer structure is composed of pairs of energy harvesting units. Each unit consists of two parts: the rotational blades with copper electrodes that are attached to the center shaft and the stationary disk that is fixed on the external barrier structure. Compared to the previous two-plate structure, the current device has two unique merits: First, both sides of the stationary disk are coated with electret material and are corona charged. It is beneficial to maximize the output power density of the whole device. Second, with the help of the micro rotary bearing, multilayer rotary structure has been successfully implemented for the first time. Therefore, the overall performance has been multiplied by several folds and high output power can be readily achieved.
