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...

This paper presents a platform for power autonomous wireless energy meter device using piezoelectric energy harvesters. This device can be mainly used for measuring the share of heat energy consumption in a fair manner in building complex with central heat energy system. In the suggested device, the piezoelectric energy harvester is also used as a flow-meter to reduce the power consumption of t...

In this article, we report on the new design of a miniaturized strain microsensor. The proposed sensor utilizes the piezoresistive properties of doped single crystal silicon. Employing the Micro Electro Mechanical Systems (MEMS) technology, high sensor sensitivities and resolutions have been achieved. The current sensor design employs different levels of signal amplifications. These amplificati...

The fabrication of electronic devices, such as gas sensors on flexible polymer substrates, enables the use of electronics in applications where conventional devices on stiff substrates could not be used. We demonstrate the development of a new intra-tube electronic-nose (e-nose) gas sensor device with multiple sensors fabricated and integrated on a flexible substrate. For this purpose, we devel...

In this work we investigate a novel design approach and signal transduction concepts for micromachined calorimetric flow sensors. Maintaining a constant average excess temperature of the membrane by means of a simple two-state electronic controller, a pulse modulated actuation signal is obtained. The sensitivity of the output signal can be influenced by altering the amplitude of the heating pul...

Miniaturization and integration of chemical devices into modules that are dimensionally comparable with electronic chips (Lab on Chip) is nowadays developing worldwide. The aim of our work was to suggest and optimize the best conditions for fabrication of TFT sensor due to its sensitivity and low experimental deviations. New electrochemical analytical device was developed to ensure certain know...

Great effect of three way catalytic convertor (TWC) performance on oxygen sensor output voltage has made the sensor (located after catalyst) as the main signal in almost all today’s TWC monitoring algorithms. In this paper output voltage of nonlinear oxygen sensor is estimated using a nonlinear autoregressive with exogenous inputs (NARX) model. The estimation uses ECU calculated exhaust gas flo...
