Ultrasoft Liquid Metal Elastomer Foams with Positive and Negative Piezopermittivity for Tactile Sensing

Yegor Piskarev, Yang Li, Michael Dickey, Jianhang Yang

Soft, capacitive tactile (pressure) sensors are important for applications including human-machine interfaces, soft robots, and electronic skins. Such capacitors consist of two electrodes separated by a soft dielectric. Pressing the capacitor brings the el ...

Tuning Interaction Parameters of Thermoplastic Polyurethanes in a Binary Solvent To Achieve Precise Control over Microphase Separation

Oguzhan Oguz

Thermoplastic polyurethanes (TPUs) are designed using a large variety of basic building blocks but are only synthesized in a limited number of solvent systems. Understanding the behavior of the copolymers in a selected solvent system is of particular inter ...

Hierarchical porous structure

Dominique Pioletti, Pierre-Etienne Bourban, Matteo Gregorio Modesto Marascio

Cellular thermoplastic structures with hierarchical multi-scale porosity (preferably 1-300 µm micro-porosity to 0.3-10 mm macro-porosity) are produced from an integrated approach of 3D printing, preferably by Fused Deposition Modeling (FDM), and of supercr ...

Liquid CO2 processing of solid polylactide foam precursors

John Christopher Plummer, Yonghoon Yoon

Diffusion of CO2 in polylactide was modelled by assuming the diffusion coefficient to depend on CO2 concentration, c, according to D[c]=D[0]exp[Ac], where D[0] and A are empirical constants, with the aim of optimizing impregnation of nominally amorphous an ...
