Multiple temperature sensors embedded in an ultrasonic “spiral-like” waveguide

open access: yesAIP Advances, 2017
This paper studies the propagation of ultrasound in spiral waveguides, towards distributed temperature measurements on a plane. Finite Element (FE) approach was used for understanding the velocity behaviour and consequently designing the spiral waveguide.

Non destructive investigation of defects in composite structures by fullfield measurement methods [PDF]

open access: yes, 2013
This paper presents different interests of non destructive full-field measurement. More precisely, it focuses on the characterization and the comparison of the X-ray tomography and two methods of infrared thermography in order to define the defect ...

Microwire-Based Sensor Array for Measuring Wheel Loads of Vehicles

open access: yesSensors, 2019
In this paper, a magnetic microwire-based sensor array embedded under the pavement is proposed as a weighing system at customs ports of entry. This sensor is made of a cementitious material suitable for embedding within the core of concrete structures ...
