Corrosion Monitoring Using Embedded Piezoelectric Sensors
In this research, a new type of corrosion monitoring technique for reinforce concrete was developed. The technique used piezoelectric sensors to detect the ultrasonic signals during corrosion. The mechanism of the method was presented. Experiment was carried out to monitor the corrosion process using piezoelectric sensors. The corrosion was also monitored using stain gauge for comparison.
متن کاملMeasurement of the Piezoelectric Properties of Vinylidene Fluoride Oligomer Using Pneumatic Pressure for Tactile Sensors∗
Vinylidene fluoride [VDF] oligomer is a novel substance with a smaller number of VDF units and lower molecular weight than poly(vinylidene fluoride) [PVDF]. We previously reported that the piezoelectric coefficient of VDF oligomer was greater than that of vinylidene fluoride/trifluoroethylene copolymer [P(VDF/TrFE)], and that a film composed of VDF oligomer was thin and uniform. However, the pi...
متن کاملBed-Leaving Detection Using Piezoelectric Unrestrained Sensors and Its Measurement System Regarding QOL
Abstract This paper presents a sensor system that predicts behavior patterns that occur when a patient leaves a bed. We originally developed plate-shaped sensors using piezoelectric elements. Existing sensors such as clip sensors and mat sensors require that patients be restrained. The features of our sensors are that they require no power supply or patient restraint for privacy problems. Moreo...
متن کاملStatic and Dynamic Measurement of Force Transducer’s Deformation under Load
− At PTB, one designed and investigated measurement setups to determine the deformation of force transducers while applying a static or dynamic force. To measure the deformation, a differential vibrometer [1] is used which is integrated in the measurement setups. Using the deformation results one is able to calculate the transducers stiffness. An evaluation of the measurement uncertainty is pre...
متن کاملA New Sensor for Static and Dynamic Force Measurement
In this work an innovative sensor for the measurement of forces is presented. The sensor is a thin film (1 mm thickness) based on a “sandwich” structure composed of two sensing elements glued together: one layer is a capacitive film and the other is a piezoelectric film. Both the layers are sensitive to compression loads, but they are suitable for working in different frequency ranges. In fact,...
