Strain and damage sensing? 2022 Elsevier LtdThe present paper demonstrates an inexpensive and less labor-intensive machine vision-based strain and damage visualization technique compared to traditional carbon fiber reinforced polymer material inspection methods. This technique is used to characterize the ...
Carbon fiber provides strain sensing through change in electrical resistance upon strain. Due to piezoresistivity of various origins, a single carbon fiber in epoxy, an epoxy-matrix composite with short carbon fibers (5.5 vol%), a cement-matrix composite with short carbon fibers (0.2–0.5 vol%)...
The interest in structural health monitoring of carbon fiber-reinforced polymers using electrical methods to detect damage in structures is growing because once the material is fabricated the evaluation of strain and damage is simple and feasible. In order to obtain the conductivity, the polymer ...
[145], fabricated rGO/Pillared carbon(PC)-type graphene oxide frameworks (GOFs) by using rGO as the original framework. Afterwards, a layer of W was deposited on the upper and lower surfaces of the GOFs to prepare rGO/PC/W, which has excellent pressure sensing, electrically and thermally ...
Conductive material-coated yarns are also attractive for developing both linear strain sensors and such yarns-integrated strain sensing devices. Conductive polymers coating is one commonly used approach. In one research, by using in situ polymerization, poly(3,4-ethylenedioxythiophene) (PEDOT)-coated ...
Distributed microcrack propagation based on the “island-bridge” structure was explained in detail, and its influence on the strain-sensing behavior of the sensor was analyzed. Finally, the sensor was assembled to monitor various vibration signals and human motions, demonstrating its potential ...

The self-sensing of flexural strain and damage has been demonstrated in carbon fiber polymer-matrix composite by measuring the DC electrical resistance. Upon strain in the elastic regime, the compression surface resistance decreases reversibly (due to increase in the current penetration), while the te...
6.7.1.3 Strain-Sensing Coating Instead of constructing the entirety of a concrete component by using carbon fiber–reinforced concrete, which is more expensive than conventional concrete, carbon fiber–reinforced concrete can be used as a coating on conventional concrete. The coating can be on one ...
A wind turbine blade with strain sensing functionality includes a surface structure, a block sensor unit including an optical sensor mechanism for sensing strain in the blade, and a
