An implantable, compatible and networkable nanocomposite piezoresistive sensor for in situ acquisition of dynamic responses of CFRPs

When sensors are embedded in composites for structural integrity monitoring (SIM), the sensors per se, unfortunately, degrade the original integrity of host composites. Envisaging such deficiency and facilitated by advances in nanotechnology, we develop a new type of ultrathin, piezoresistive sensors using spraying coating and nanocomposites formulated with graphene nanoplatelets/polyvinylpyrrolidone. The sensors are deposited on dielectric...
