Non-reciprocal light transmission in integrated photonic systems via acousto-optic interaction
… acousto-optic interaction in PICs. Co-fabricated electromechanical transducers are used to launch traveling acoustic waves that modulate integrated photonic components. We also show that the direction of non-reciprocity can be dynamically controlled by changing the acoustic wave direction. Using …

Development of Devices Based on Electrically Actuated Soft Elastomers
Dielectric elastomer (DE) actuators are electromechanical transducers that essentially consist of one layer of an insulating soft elastomer coated on both sides with com- pliant electrodes. When a voltage is applied between the electrodes, an electrostatic pressure deforms the elastomer triggering …

Characterization and Modeling of the Ionomer-Conductor Interface in Ionic Polymer Transducers
Ionomeric polymer transducers consist of an ion-exchange membrane plated with conductive metal layers on its outer surfaces. Such materials are known to exhibit electromechanical coupling under the application of electric fields and imposed deformation (Oguro et al., 1992; Shahinpoor et al., 1998). …
