Mechanically adaptive nanocomposites for neural interfacing

Stimuli-responsive mechanically adaptive polymer nanocomposites.

A new series of biomimetic stimuli-responsive nanocomposites, which change their mechanical properties upon exposure to physiological conditions, was prepared and investigated. The materials were produced by introducing percolating networks of cellulose nanofibers or "whiskers" derived from tunicates into poly(vinyl acetate) (PVAc), poly(butyl methacrylate) (PBMA), and blends of these polymers,...

In vivo deployment of mechanically adaptive nanocomposites for intracortical microelectrodes.

We recently introduced a series of stimuli-responsive, mechanically adaptive polymer nanocomposites. Here, we report the first application of these bio-inspired materials as substrates for intracortical microelectrodes. Our hypothesis is that the ideal electrode should be initially stiff to facilitate minimal trauma during insertion into the cortex, yet become mechanically compliant to match th...

Interfacing with adaptive systems

We cast a design view on the interactions that occur when humans face (interconnected) adaptive systems. As humans are also adaptive, the combined behavior of such systems and humans can exhibit various phenomena that are especially of concern to designers of adaptive systems dealing with the inherent complexity of systems, systems’ interfaces, interconnectivity, and other design factors. Based...

A Graphene Oxide Nanocomposite for Neural Interfacing

Progress of Flexible Electronics in Neural Interfacing - A Self-Adaptive Non-Invasive Neural Ribbon Electrode for Small Nerves Recording.

A novel flexible neural ribbon electrode with a self-adaptive feature is successfully implemented for various small nerves recording. As a neural interface, the selective recording capability is characterized by having reliable signal acquisitions from the sciatic nerve and its branches such as the peroneal nerve, the tibial nerve, and the sural nerve.
