Piezoresistive characteristics of PDMS and copper composite with critical pressure |
| 초록 |
The piezoresistive behavior of polydimethylsiloxane (PDMS) filled with copper particles under different pressure ranges are investigated. The experimental results exhibited the various piezoresistive behaviors where a critical pressure where the electrical resistance decreases first and then increases. The critical pressure of composite was increased with copper concentration. The gauge factor of the composite was then calculated from the data at different stress and strain. As the composite strain is kept constant, the electrical resistance and the stress both decrease with time. After repeated pressure treatment, there was a decrease in the change of conducting structure due to the irreversible deformation of polymer matrix. The behaviors were explained by the tunneling conduction theory which provides a good approximation to the piezoresistive effect. |
