Phase Shift Oscillator Circuit Using Op-amp

The conventional sine wave oscillator circuits use phase shifting techniques that RC phase shift oscillator using op-amp in inverting amplifier introduces. Figure show a RC phase shift oscillator using Op-Amp with gain 5(Vo/Vi). My assumption : Circuit is generating a sine wave with a peak to peak voltage of 10v. Voltage stability, specifically the lack of, when using a resister divider is the ...

Strain Measurement of Carbon Composites Using Advanced Sensor Technology

This paper reports the sensor integration method into carbon composites for the development of Structural Health Monitoring (SHM). Early detection and long term monitoring of the specific properties of composites will improve the security and prolong the time of service 1 . The core function of SHM is the damage detection and identification at elevated temperatures, over loads and corrosion. Va...

Measurement of Temperature, Humidity and Strain Variation Using Bragg Sensor

Measurement and monitoring of temperature, humidity and strain variation are very requested in great fields and areas such as structural health monitoring (SHM) systems. Currently, the use of fiber Bragg grating sensors (FBGS) is very recommended in SHM systems due to the specifications of these sensors. In this paper, we present the theory of Bragg sensor, therefore we try to measure the effic...
