Implantable Left Ventricular Assist Devices and the Kidney [PDF]

Blood Purification, 2014
The use of left ventricular assist devices (LVADs) in treating patients with advanced heart failure restores cardiac output resulting in improved perfusion to multiple organ systems with important clinical benefits. Renal pathophysiology during LVAD support remains an evolving, poorly understood, and potentially dynamic problem.

3D Printing of Conducting Polymer Hydrogels for Electrostimulation‐Assisted Tissue Engineering

Advanced Materials, EarlyView.
This review highlights nanosized inherently conducting polymers (ICPs) as promising ink constituents for 3D printing of conducting hydrogel (CH)‐based electrostimulation (ES) devices. ICP‐based ink formulation, 3D printing, and solidification strategies are discussed, along with the application of 3D‐printed ICP‐based CHs as ES platforms for regulating

Design of a Simple and Rugged Soft Polydimethylsiloxane‐Carbon Nanotube‐Graphene‐Based Composite Sensor

Advanced Materials Technologies, EarlyView.
This research presents an easy to fabricate, low‐cost, flexible piezoresistive deformation sensor comprised of a carbon nanotube, few‐layer graphene, and polydimethylsiloxane composite. The sensor detects deformations and vibrations up to 600 Hz with 0.1% strain sensitivity from stiff and soft targets in dry and wet environments.
