In this work we investigate the piezoresistive effect in multilayer graphene (MLG) based films produced by two different cost-effective techniques, spray coating and drop casting. Both techniques enable the direct deposition of the sensor over the structure to be monitored. The piezoresistive behavior of the MLG-based sensors has been investigated experimentally by measuring the variation of the electrical resistance during three point bending tests. The sensor response has been stabilized through an optimized mechanical treatment. The obtained results show that the produced sensors are characterized by a gauge factor in the range 20–50 at very small strains (i.e. below 0.2%).

Abstract
In this work we investigate the piezoresistive effect in multilayer graphene (MLG) based films produced by two different cost-effective techniques, spray coating and drop casting. Both techniques enable the direct deposition of the sensor over the structure to be monitored. The piezoresistive behavior of the MLG-based sensors has been investigated experimentally by measuring the variation of the electrical resistance during three point bending tests. The sensor response has been stabilized through an optimized mechanical treatment. The obtained results show that the produced sensors are characterized by a gauge factor in the range 20–50 at very small strains (i.e. below 0.2%).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
