Nanomechanical probing of thin-film dielectric elastomer transducers

Dielectric elastomer transducers (DETs) have attracted interest as generators, actuators, sensors, and even as self-sensing actuators for applications in medicine, soft robotics, and microfluidics. Their performance crucially depends on the elastic properties of the electrode-elastomer sandwich structure. The compressive displacement of a single-layer DET can be easily measured using atomic force microscopy (AFM) in the contact mode.

Flex-ANA automated data data acquisition and analysis software running on a FlexAFM system was used to extract the indentationdepths for each measurement.
