Design 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...

1. Introduction Recently, very small antennas are requested in RFID tags and tire attached sensors of the tire pressure monitoring system (TPMS). In these applications, normal-mode helical antennas (NMHA) are interested that can achieve high antenna efficiencies at very small size such as 1/100 wavelengths. Moreover, NMHA can increase antenna gains in the metal plate proximity use. However, NMH...
متن کاملLow-cost Vector Network Analyzer for Biomedical Applications
A low-cost and portable vector network analyzer (VNA) which covered operating frequency between 1MHz to 3GHz is used for vector reflection coefficient and standing wave ratio (swr) of the various microstrip antennas. This paper presents measurements of various ultra wideband (uwb) microstrip antennas for applications in biomedical field. Selection of antenna is an important key for detection of...
