An investigation of PDMS structures for optimized ferroelectret performance
نویسنده
چکیده
This paper reports the ANSYS simulation and fabrication processes for optimising PDMS ferroelectret performance. The proposed model extends the previously published analytical models and combines this with simulation of individual void geometry. The ferroelectret material is fabricated from PDMS using 3D-printed plastic mould. Mathematic model and Ansys simulation results predict that the performance of PDMS ferroelectret is varied with the geometry of voids and surface charge density, and the theoretical maximum piezoelectric coefficient d33 achieved was about 220 pC/N. The experimental maximum d33 obtained was 172 pC/N.

Novel thick-foam ferroelectret with engineered voids for energy harvesting applications
This work reports a novel thick-foam ferroelectret which is designed and engineered for energy harvesting applications. We fabricated this ferroelectret foam by mixing a chemical blowing agent with a polymer solution, then used heat treatment to activate the agent and create voids in the polymer foam. The dimensions of the foam, the density and size of voids can be well controlled in the fabric...
متن کاملINVESTIGATION OF NON-LINEAR CYCLES’ PROPERTIES IN STRUCTURES SUBJECTED TO ENDURANCE TIME EXCITATION FUNCTIONS
Endurance Time Method (ET) is a dynamic analysis in which structures are subjected to intensifying accelerograms that are optimized in a way that seismic performance of structures can be estimated at different hazard levels with the best possible accuracy. For the currently available ET accelerograms, regardless of the shaking characteristic, an excitation level is recognized as a representativ...
