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...

HDAC7 inhibits osteoclastogenesis by reversing RANKL-triggered β-catenin switch.

The bone-resorbing osteoclast is essential for skeletal remodeling, yet its deregulation contributes to diseases such as osteoporosis and cancer bone metastasis. Here we identify histone deacetylase 7 (HDAC7) as a key negative regulator of osteoclastogenesis and bone resorption using both in vitro cellular and molecular analyses and in vivo characterization of conditional HDAC7-knockout mice. B...

Four-wire orthogonal structure for accurate measurement of fluid velocity and wind flow direction using silicon micro-machining on silicon nitride membranes

Microelectromechanical thermal sensors are one of the most accurate and important tools for measuring the direction and velocity of an acoustic wave and winds. Detection of wind direction and speed in different ranges has different applications such as meteorology, wind power plants, gas flow measurement in smart building and gas consumption of power plants. In this paper, a four wires sensor i...
