External-Strain Induced Insulating Phase Transition in VO2 Nanobeam and Its Application as Flexible Strain Sensor
The insulating phase transition in a VO2 nanobeam when subjected to external-strain is utilized to fabricate a quick response time, highly reproducible, and high gauge factor strain sensor. Raman spectroscopy combined with electromechanical measurement reveals the working principle.
