Abstract:
A 50,000g three-axis accelerometer using a single proof mass is presented. The sensitive structure is made of a single proof mass and eight cantilever beams. Twelve piezoresistors are placed on the cantilevers symmetrically, which can be used to detect 3-dimensional acceleration. The symmetric placement of the piezoresistors brings the reasonable sensitivity and simultaneously decreases the cross-axis sensitivity significantly. Simulation results show that the sensitivity in X-, Y- and Z-axis are 0.806uV/g, 0.806uV/g and 3.71uV/g respectively with 5V supply and the cross-axis sensitivities are all less than 2.4%, which ensures the high performance of the three-axis accelerometer.

Abstract:
In this paper, a new design technique is presented to estimate and reduce the cross-axis sensitivity (CAS) in a single-drive multi-axis microelectromechanical systems (MEMS) gyroscope. A simplified single-drive multi-axis MEMS gyroscope, based on a mode-split approach, was analyzed for cross-axis sensitivity using COMSOL Multiphysics. A design technique named the “ratio-matching method” of drive displacement amplitudes and sense frequency differences ratios was proposed to reduce the cross-axis sensitivity. Initially, the cross-axis sensitivities in the designed gyroscope for x and y-axis were calculated to be 0.482% and 0.120%, respectively, having an average CAS of 0.301%. Using the proposed ratio-matching method and design technique, the individual cross-axis sensitivities in the designed gyroscope for x and y-axis were reduced to 0.018% and 0.073%, respectively. While the average CAS was reduced to 0.045%, showing a reduction rate of 85.1%. Moreover, the proposed ratio-matching method for cross-axis sensitivity reduction was successfully validated through simulations by varying the coupling spring position and sense frequency difference variation analyses. Furthermore, the proposed methodology was verified experimentally using fabricated single-drive multi-axis gyroscope.

Abstract:
The anisotropic magnetoresistive (AMR) sensors provide an excellent means of measuring the earth’s magnetic field. Low cost, high sensitivity, small size, noise immunity, and reliability are advantages of AMR sensor over other electrical alternatives. But the sensitivity of constant voltage biased AMR sensor changes greatly with the temperature of surrounding and cross-axis field. In this paper, constant current bias is used in order to reduce the sensitivity temperature coefficient of AMR sensor. At the same time, cross-axis field compensation is taken based on iteration. The results of experiment show that the sensitivity of HMC100x without cross-axis field compensation varies greatly with the variation of cross-axis field, the sensitivity of HMC100x with cross-axis field compensation is stable. It can be seen that proposed sensitivity compensation method is effective. Developed magnetometer is used for vehicle detection. Experimental results show that developed magnetometer is capable of detecting vehicle and its output variation curve shape is different for the ferrous cart moves over sensor along different direction.

This research developed a microaccelerometer via Computer-Aid-Design(CAE) and Micro Electro Mechanical Systems(MEMS) with high performance in linearity and cross-axis sensitivity. Unlike the conventional sensing elements which are always embedded at the position of maximum displacement, the present study situated the sensors at the locations where the maximum displacements of the structure are generated in order to raise up the maximal output than the former. The core elements of accelerometer includes a vertical, double-ended flexural beam, a proof mass integrated at the middle section of the beam, and four suspended piezoresistors fixed at the mass block and across the trenches to the anchor pads. The mass block had maximum displacements of the dynamic structure which would activate the sensors to deliver maximal output. It was simulated by numerical method to analyze how much and where the maximal stress would be. The sensing chip was fabricated on a silicon-on-insulator(SOI) wafer through MEMS processes and installed by Dual-In-Package. The accelerometer was placed on a rate table that provided stable centrifugal acceleration up to approximately 3000 G for quasi-static testing. The output voltage of the accelerometer was digitized and radiofrequency transmitted for remote data acquisition. The natural frequency was about 232.4 kHz from mode analysis. After numerous experiments, the correlations for the individual runs showed that the accelerometer had a sensitivity of 3.0015 μV/Vexc/G with extraordinary performance. The best linearity of the sensing output was only 0.11% of full scale output (FS, or 59 dB), as deduced from the average standard deviation of all test runs. The average of the maximum reading deviations from the corresponding correlated curves was approximately 0.26% FS. Moreover, the cross-axis sensitivity for the two orthogonal directions nearly vanished in the test range. With the high rigidity of the microstructure, the accelerometer exhibited an ultra high performance factor of 25.8 x 10^6 MHz. The accelerometer possessed exceptional sensitivity, linearity, and repeatability, and extremely low cross-axis interference and noise.

Abstract:
This chapter on genetics of stress-related disorders reviews the state of the art in molecular variations associated with post-traumatic stress disorder (PTSD), including cross-disorder phenotypes like anxiety sensitivity, state/trait anxiety, and harm avoidance. It summarizes the wealth of information collected in family and twin studies, genome-wide association studies (GWAS), and candidate gene, gene–environment, and epigenetic investigations. The molecular overlap between PTSD and anxiety disorders is highlighted. Emphasis is laid upon findings relating to serotonin, catecholamine, and the hypothalamic–pituitary–adrenal (HPA) axis signalling pathways, as well as the integration of physiological, imaging, and psychological readouts. Genetic variants linked to treatment response prediction, susceptibility, and resilience, as well as disease course, are discussed, and the complexity of gene–environment interactions in PTSD is addressed. Finally, a future outlook is offered into personalized therapy and innovative drug discovery, dimensional psychopathology, and polygenic risk evaluation in light of dynamic epigenetic markers and systems biology-informed nosology.

Abstract:
A novel bending plate capacitive strain gauge is designed, fabricated, and tested to measure strain in the range of 1 to 1000 με. This silicon-based strain sensor uses a unique structural design to increase the on-axis gain through the use of a bending beam structure while attenuating signals due to cross-axis strain. A differential capacitive measurement is used to improve the output, reduce the parasitic capacitance, and eliminate the capacitance measurement error due to temperature. The device is fabricated using silicon-on-insulator (SOI) technology. Experimental results exhibit an on-axis sensitivity of 50 aF/με and attenuation of the cross-axis sensitivity to shear strain to less than 10 percent of the applied shear strain. A detailed mechanical analysis of the suspension and deflection-amplifying bent-beam capacitor will be presented. Furthermore, the capacitive plate analytical model is compared to finite element simulations and verified with experimental results. In addition, a noise assessment of the device shows the electronics noise dominates the Brownian noise.
