New Design of Mems piezoresistive pressure sensor
The electromechanical analysis of a piezoresistive pressure microsensor with a square-shaped diaphragm for low-pressure biomedical applications is presented. This analysis is developed through a novel model and a finite element method (FEM) model. A microsensor with a diaphragm 1000 „m length and with thickness=400 µm is studied. The electric response of this microsensor is obtained with applyi...
متن کاملModeling of capacitance and sensitivity of a MEMS pressure sensor
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...
متن کاملWireless Communication for Tire Pressure Monitoring System Based on ARM7TDMI
Today safety of the human life is major concern. Nowadays about 75% of the casualties has been observed due to the accidents during transport of the vehicle. These are especially due to the flaw in the tire pressure. Tire break avoiding is very important for safe driving in superhighway. Wireless Tire Pressure Monitoring System (TPMS) is used to detect whether one or more of the vehicle’s tire ...
متن کاملTraffic Data Collection Using Tire Pressure Monitoring System
In this paper we present initial results in utilization of TPMS (Tire Pressure Monitoring System) for collecting traffic data and deriving traffic information, i.e. travel times. The obtained results show that current detection ratio is less than 5 % and the obtained travel times are in consistency with referent data. The experiment is performed on DLR test track in Berlin. In particular, archi...
متن کاملDesign of High Sensitivity and Linearity Microelectromechanical Systems Capacitive Tire Pressure Sensor using Stepped Membrane
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...
