| Abstract Scope |
This work presents a straight-forward preparative access to silicon oxycarbide-based (SiOC) thin films as strain gauges possessing outstanding high-temperature robustness and giant piezoresistive response.
The SiOC-based thin film strain gauge exhibits gauge factors of ca. 2000−5000 upon tensile and compressive loeading . The linearity of the response is preserved up to 700 °C. Notably, the studied SiOC-based thin films can regulate the effect of temperature enabling them to be a highly sensitive device with good reversibility and replicability in high-temperature environments. |
