The orientation dependence of the piezoresistive effect of p-type single crystalline 3C-SiC thin film grown on a (100)Si wafer was characterized. The longitudinal, transverse gauge factors in [100] orientation, and longitudinal gauge factor in [110] orientation were found to be 5.8, −5.2, and 30.3, respectively. The fundamental piezoresistive coefficients π11, π12, and π44 of p-type 3C-SiC were obtained to be 1.5 × 10−11 Pa−1, −1.4 × 10−11 Pa−1, and 18.1 × 10−11 Pa−1, respectively. From these coefficients, the piezoresistive effect in any crystallographic orientation in p-type single crystalline 3C-SiC can be estimated, which is very valuable in designing micro-mechanical sensors.

An integrated vehicle dynamics control (IVDC) algorithm, developed for improving vehicle handling and stability under critical lateral motions, is discussed in this paper. The IVDC system utilises integral and nonsingular fast terminal sliding mode (NFTSM) control strategies and coordinates active front steering (AFS) and direct yaw moment control (DYC) systems. When the vehicle is in the normal driving situation, the AFS system provides handling enhancement. If the vehicle reaches its handling limit, both AFS and DYC are then integrated to ensure the vehicle stability. The major contribution of this paper is in improving the transient response of the vehicle yaw rate and sideslip angle tracking controllers by implementing advanced types of sliding mode strategies, namely integral terminal sliding mode and NFTSM, in the IVDC system. Simulation results demonstrate that the developed control algorithm for the IVDC system not only has strong robustness against uncertainties but also improves the transient response of the control system.

We have fabricated and demonstrated a micromachined electrometer with a charge resolution of 6 e/ √ Hz, operating at room temperature and ambient pressure. We thus show that high-resolution electrometry is realizable at room temperature and competitive with alternative low temperature (<10 K) solutions. The device presented in this paper functions as a modulated variable capacitor, wherein a dc charge to be measured is modulated and converted to an ac voltage output. By reviewing a selection of different devices based on this concept, we show that single-electron charge resolution at room temperature and ambient pressure is achievable with the aid of practical design considerations.
