The consists of chain-slot-shaped pattern on mobile phone metal frame. is fed using transmission line, which would cause only negligible capacitive loading the sub-6 GHz realized same frame and, therefore, not significantly degrade its performance. makes colocating and mm-wave antennas in sa...

Silicon Laboratories' capacitive sensing techniques are compatible with external ESD protection methods. Designers should be aware of parasitic parameters in these circuits which affect capacitive sensing performance when implementing these protection methods. While most of the methods affect sensing performance in some way, in almost all cases an acceptable balance between performance, protect...

This article presents a software tool to automatically generate the mathematical model of capacitive MEMS gyroscopes in a symbolic form. After describing the operational principle of a specific one-axis gyroscope with capacitive drive actuators and capacitive sensors, a mathematical concept is presented that allows for the systematic description of a certain class of capacitive MEMS gyroscopes....

<p>When wind energy conversion systems (WECS) are integrated with the Grid system then there power quality issues arises. The fluctuation in delivery to grid demands robust control for a better quality. Therefore, voltage and frequency stability due integration of is primary concern improve overall capability WECS. This paper reviews introduction WECS introduces dynamic that include sub-s...

For more than two decades, capacitive sensing has played a prominent role in human-computer interaction research. Capacitive sensing has become ubiquitous on mobile, wearable, and stationary devices—enabling fundamentally new interaction techniques on, above, and around them. The research community has also enabled human position estimation and whole-body gestural interaction in instrumented en...

Projected capacitive touch panels have been widely used in many mobile application systems such as smartphones and tablet PCs. We fabricated projected capacitive-type touch sensors using printed circuit boards. It has equivalent parasitic capacitive loads with a 10” touch panel. In this paper, we discuss projected capacitive touch technologies and their highperformance touch controllers. We int...

In this paper modeling of capacitance and sensitivity for MEMS capacitive pressure sensor is presented. In capacitive sensor the sensitivity is proportional to deflection and capacitance changes versus pressure. Therefore first the diaphragm displacement, capacitance and sensitivity of sensor with square diaphragm have been modeled and then simulated using finite element method (FEM).  It can b...

This paper is focused on a novel design of stepped diaphragm for MEMS capacitive pressure sensor used in tire pressure monitoring system. The structure of sensor diaphragm plays a key role for determining the sensitivity of the sensor and the non-linearity of the output.First the structures of two capacitive pressure sensors with clamped square flatdiaphragms, with different thicknesses are inv...
