Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

We report a new method for maintaining constant z-axis displacement of an electrostatic torsional micromirror driven by quadrant electrodes, by adding an additional control electrode. The voltage applied to the control electrode is theoretically related to the voltages applied to the quadrant electrodes. The mathematical model is presented and validated through finite-element analysis.
