Sensing with Thermally Reduced Graphene Oxide under Repeated Large Multi-Directional Strain.
Sensors (Basel)
September 2024
Article Synopsis
- The study explores the electromechanical properties of thermally reduced graphene oxide (rGO) as a highly sensitive strain sensor, capable of withstanding mechanical strains up to 20.72%.
- It reveals that rGO can be easily synthesized on PDMS substrates, showing linear electrical resistance behavior up to about 7.5% strain, after which nonlinear behavior occurs.
- Hysteresis testing indicates that the sensor demonstrates a consistent electromechanical response over multiple loading cycles, with a gauge factor of 91.50, highlighting its potential for practical applications in strain sensing.
The adhesion strength of thin films is critical to the durability of micro and nanofabricated devices. However, current testing methods are imprecise and do not produce quantitative results necessary for design specifications. The most common testing methods involve the manual application and removal of unspecified tape.
