History of breast implants: Back to the future

open access: yesJPRAS Open, 2022
Summary: Modern breast implants are a staple of plastic surgery, finding uses in esthetic and reconstructive procedures. Their history began in the 1960s, with the first generation of smooth devices with thick silicone elastomer, thick silicone gel, and ...

Novel silicone elastomer formulations for DEAPs [PDF]

open access: yes, 2013
We demonstrate that the force output and work density of polydimethylsiloxane (PDMS) based dielectric elastomer transducers can be significantly enhanced by the addition of high permittivity titanium dioxide nanoparticles which was also shown by Stoyanov

Super-stretchable silicone elastomer applied in low voltage actuators

open access: yes, 2021
Enabling desirable actuations at low voltages for silicone based dielectric elastomer actuators (DEAs) is challenging. Reducing the thickness and increasing the softness of the silicone film are key approaches for this purpose.

Effect of Barium Titanate Particle Filler in Soft Silicone Films on their Application in Dielectric Elastomer Actuators

open access: yes, 2023
8891Dielectric elastomer actuators (DEA) consist of a thin dielectric elastomer film sandwiched between two compliant electrodes. The force and deformation provided by these actuators depend substantially on the electrical and mechanical material ...

Self-Healing, High-Permittivity Silicone Dielectric Elastomer [PDF]

open access: yes, 2016
Currently used dielectric elastomers do not have the ability to self-heal after detrimental events such as tearing or electrical breakdown, which are critical issues in relation to product reliability and lifetime.

Effect of MWCNTs Dispersion and Loading on the Rheological and Electrical Properties of MWCNTs/Silicone Composite

open access: yesMATEC Web of Conferences, 2016
The dispersion of multiwalled carbon nanotubes (MWCNTs) in silicone was significantly affected by the method of mixing. In this study, rheology showed that there was an optimal mixing time to get the MWCNTs disperse well and high loading of MWCNTs made ...

Air‐Pressure–Actuated Vibroacoustic Metamaterial With Tunable Bandgap: Design, Modeling, and Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.

The Antibacterial Activities of Ag/$Nano-TiO_2$ Modified Silicone Elastomer

open access: yes, 2014
We studied the ability of Ag/$nano-TiO_2$ to inhibit Staphylococcus aureus growth on silicone elastomer material. Ag/$nano-TiO_2$ silicone elastomer was prepared with different concentrations of 0%, 2%, 4%, 6%, 8%, 10%.

Evaluating Energy Absorption Performance of Filled Lattice Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...
