Sensitivity of the sensor is great importance in practical applications wearable electronics or smart robotics. In present study, a capacitive enhanced by tilted micropillar array-structured dielectric layer developed. Because micropillars undergo bending deformation rather than compression deformation, distance between electrodes easier to change, even discarding contribution air gap at interface structured and electrode, thus resulting high pressure sensitivity (0.42 kPa-1) very small...
Continuous fiber reinforced polymer composites (CFRPC) have been widely used in the field of automobile, aircraft, and space due to light weight, high specific strength modulus comparison with metal as well alloys. Innovation on 3D printing CFRPCs opened a new era for design fabrication complicated composite structure performance low cost. provided an enabling technology bridge gaps between advanced materials innovative structures. State-of-art has reviewed according correlations materials,...
A linearization method with improved robustness for determining the displacement from sine and cosine signals generated by optical encoders is presented. The proposed scheme based on a ratiometric technique dedicated compensation method. converts sinusoidal into nearly perfectly linear output signal, which determined precisely using simple equation. Under condition of ideal input signals, theoretical analysis shows that converter enables determination non-linearity error below 0.0029 µm...
Electronic interpolation is the key technology for further improving measurement resolution of optical encoders. In this paper, an electronic interpolator based on ratiometric linearization conversion method presented. The proposed converts sinusoidal encoder signals into a nearly perfectly linear output signal through mathematical manipulation that only involves basic operations addition, subtraction, multiplication, and division. Thus, displacement can be precisely determined using simple...

Abstract To explore the effect of process parameters on bead geometry in cold metal transfer wire arc additive manufacturing(CMT-WAAW), response surface optimization method was adopted this paper. According to previous experiments, some were selected as independent variables. They are feed speed(WFS), traveling speed(TS) and substrate temperature(ST). Some geometric welding dependent track width (w), layer height (h), penetration (p), accumulated area (A2), (A1), aspect ratio (B) dilution...
