Polydimethylsiloxane and polyisoprene-based graphene composites for strain-sensing

Deformable Strain Sensors Based on Patterned MWCNTs/ Polydimethylsiloxane Composites

Patterned MWCNT/polydimethylsiloxane (PDMS) nanocomposite strain sensors were achieved by a microelectromechanical system assisted electrophoretic deposition (EPD) technique. With the combined effect of superior intrinsic piezoresistivity of the individual MWCNT and the tunneling effect of the MWCNT network, the stretchable composite demonstrates high sensitivity to the tensile strain. The gaug...

One-pot Synthesis of Conducting Graphene Polymer Composites and Its Strain Sensing Application (preprint)

Pitch-matrix composites for electrical, electromagnetic and strain-sensing applications

Pitch-matrix composites for deicing, electromagnetic shielding and strain sensing have been developed by using carbon fiber (discontinuous) and carbon black as electrically conductive fillers. A composite with carbon fiber (5 vol%) as the sole filler is effective for strain sensing, which functions by the electrical resistivity increasing reversibly with tensile strain. A composite with carbon ...

Cancer Sensors Based on Graphene and Graphene Composites

A comparison of performance of three different types of graphene biosensors for the detection of prostate specific antigen was reported. Three different graphene structures were synthesized by mechanical exfoliation, microfluidic and self assembly respectively, representing graphene composites from pure to hybrid. Various parameters of different types of graphene biosensors were compared, such ...

A Stretchable and Highly Sensitive Graphene-Based Fiber for Sensing Tensile Strain, Bending, and Torsion.

Wearable sensors are increasingly finding their way into applications of kinesthetic sensing, personal health monitoring, and smart prosthetics/robotics. A graphene-based composite fiber sensor with a "compression spring" structure is fabricated, featuring the ability of detecting multiple kinds of deformation. This fiber sensor is integrated into wearable sensors for monitoring human activitie...
