| الوصف: | Abstract The use of high electric fields, as well as pre‐stressing, are the two main obstacles to the widespread use of poly(vinylidene fluoride (PVDF)‐based actuators. In response, a new double‐sided multilayer device has been developed which, coupled with a polarization procedure, enables high bending performance at low voltages. The actuator's symmetry allows zero bending at rest, while the high number of layers enables a strong field to be maintained while reducing the applied voltage. X‐ray and permittivity studies reveal the ultimate links between the microscopic material displacement and the actuator deflection. These results, coupled with the analytical model developed in this work, demonstrate that the optimization of complex multilayer systems requires a detailed understanding of mechanics, design, and microstructure. Experimental, analytical and finite element results confirm that such a double‐sided multilayer actuator is of 50% more efficient than a conventional single‐sided actuator, up to 40 V µm−1. These achievements open up new prospects for PVDF‐based actuators in application of healthcare, such as arterial navigation. |
