The railway transportation system aims at optimal performance, lower energy usage, longer service availability, and high safety levels. This can be achieved by using smart monitoring technologies that do not disrupt train operations and increase passenger comfort. Fiber Bragg Grating (FBG) sensors on ...
This paper analyses the implementation of fibre Bragg grating (FBG) sensors as vibration sensors along a rail in order to obtain usable signals of sufficient interest for weigh-in-motion and axle counting. Particular attention is also paid to the advantages of these new sensors. This study was ...
A new application of in-fibre Bragg grating (FBG) sensors for the distributed measurement of temperature inside a polymer electrolyte membrane fuel cell is demonstrated. Four FBGs were installed on the lands between the flow channels in the cathode collector plate of a single test cell, evenly ...
Although haptic feedback is critical for many surgical tasks, surgeons cannot currently obtain haptic feedback from teleoperated surgical robots because it is difficult to attach force sensitive sensors to the surgical robot in the surgery environment. Therefore, force sensitive forceps with an optical...
